The following -more-detailed instructions are generic; see the `README' file for -instructions specific to this package. - - The `configure' shell script attempts to guess correct values for -various system-dependent variables used during compilation. It uses -those values to create a `Makefile' in each directory of the package. -It may also create one or more `.h' files containing system-dependent -definitions. Finally, it creates a shell script `config.status' that -you can run in the future to recreate the current configuration, and a -file `config.log' containing compiler output (useful mainly for -debugging `configure'). - - It can also use an optional file (typically called `config.cache' -and enabled with `--cache-file=config.cache' or simply `-C') that saves -the results of its tests to speed up reconfiguring. Caching is -disabled by default to prevent problems with accidental use of stale -cache files. - - If you need to do unusual things to compile the package, please try -to figure out how `configure' could check whether to do them, and mail -diffs or instructions to the address given in the `README' so they can -be considered for the next release. If you are using the cache, and at -some point `config.cache' contains results you don't want to keep, you -may remove or edit it. - - The file `configure.ac' (or `configure.in') is used to create -`configure' by a program called `autoconf'. You need `configure.ac' if -you want to change it or regenerate `configure' using a newer version -of `autoconf'. - -The simplest way to compile this package is: - - 1. `cd' to the directory containing the package's source code and type - `./configure' to configure the package for your system. - - Running `configure' might take a while. While running, it prints - some messages telling which features it is checking for. - - 2. Type `make' to compile the package. - - 3. Optionally, type `make check' to run any self-tests that come with - the package. - - 4. Type `make install' to install the programs and any data files and - documentation. - - 5. You can remove the program binaries and object files from the - source code directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile the package for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the package's developers. If you use it, you may have to get - all sorts of other programs in order to regenerate files that came - with the distribution. - -Compilers and Options -===================== - -Some systems require unusual options for compilation or linking that the -`configure' script does not know about. Run `./configure --help' for -details on some of the pertinent environment variables. - - You can give `configure' initial values for configuration parameters -by setting variables in the command line or in the environment. Here -is an example: - - ./configure CC=c99 CFLAGS=-g LIBS=-lposix - - *Note Defining Variables::, for more details. - -Compiling For Multiple Architectures -==================================== - -You can compile the package for more than one kind of computer at the -same time, by placing the object files for each architecture in their -own directory. To do this, you can use GNU `make'. `cd' to the -directory where you want the object files and executables to go and run -the `configure' script. `configure' automatically checks for the -source code in the directory that `configure' is in and in `..'. - - With a non-GNU `make', it is safer to compile the package for one -architecture at a time in the source code directory. After you have -installed the package for one architecture, use `make distclean' before -reconfiguring for another architecture. - -Installation Names -================== - -By default, `make install' installs the package's commands under -`/usr/local/bin', include files under `/usr/local/include', etc. You -can specify an installation prefix other than `/usr/local' by giving -`configure' the option `--prefix=PREFIX'. - - You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. If you -pass the option `--exec-prefix=PREFIX' to `configure', the package uses -PREFIX as the prefix for installing programs and libraries. -Documentation and other data files still use the regular prefix. - - In addition, if you use an unusual directory layout you can give -options like `--bindir=DIR' to specify different values for particular -kinds of files. Run `configure --help' for a list of the directories -you can set and what kinds of files go in them. - - If the package supports it, you can cause programs to be installed -with an extra prefix or suffix on their names by giving `configure' the -option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. - -Optional Features -================= - -Some packages pay attention to `--enable-FEATURE' options to -`configure', where FEATURE indicates an optional part of the package. -They may also pay attention to `--with-PACKAGE' options, where PACKAGE -is something like `gnu-as' or `x' (for the X Window System). The -`README' should mention any `--enable-' and `--with-' options that the -package recognizes. - - For packages that use the X Window System, `configure' can usually -find the X include and library files automatically, but if it doesn't, -you can use the `configure' options `--x-includes=DIR' and -`--x-libraries=DIR' to specify their locations. - -Specifying the System Type -========================== - -There may be some features `configure' cannot figure out automatically, -but needs to determine by the type of machine the package will run on. -Usually, assuming the package is built to be run on the _same_ -architectures, `configure' can figure that out, but if it prints a -message saying it cannot guess the machine type, give it the -`--build=TYPE' option. TYPE can either be a short name for the system -type, such as `sun4', or a canonical name which has the form: - - CPU-COMPANY-SYSTEM - -where SYSTEM can have one of these forms: - - OS KERNEL-OS - - See the file `config.sub' for the possible values of each field. If -`config.sub' isn't included in this package, then this package doesn't -need to know the machine type. - - If you are _building_ compiler tools for cross-compiling, you should -use the option `--target=TYPE' to select the type of system they will -produce code for. - - If you want to _use_ a cross compiler, that generates code for a -platform different from the build platform, you should specify the -"host" platform (i.e., that on which the generated programs will -eventually be run) with `--host=TYPE'. - -Sharing Defaults -================ - -If you want to set default values for `configure' scripts to share, you -can create a site shell script called `config.site' that gives default -values for variables like `CC', `cache_file', and `prefix'. -`configure' looks for `PREFIX/share/config.site' if it exists, then -`PREFIX/etc/config.site' if it exists. Or, you can set the -`CONFIG_SITE' environment variable to the location of the site script. -A warning: not all `configure' scripts look for a site script. - -Defining Variables -================== - -Variables not defined in a site shell script can be set in the -environment passed to `configure'. However, some packages may run -configure again during the build, and the customized values of these -variables may be lost. In order to avoid this problem, you should set -them in the `configure' command line, using `VAR=value'. For example: - - ./configure CC=/usr/local2/bin/gcc - -causes the specified `gcc' to be used as the C compiler (unless it is -overridden in the site shell script). - -Unfortunately, this technique does not work for `CONFIG_SHELL' due to -an Autoconf bug. Until the bug is fixed you can use this workaround: - - CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash - -`configure' Invocation -====================== - -`configure' recognizes the following options to control how it operates. - -`--help' -`-h' - Print a summary of the options to `configure', and exit. - -`--version' -`-V' - Print the version of Autoconf used to generate the `configure' - script, and exit. - -`--cache-file=FILE' - Enable the cache: use and save the results of the tests in FILE, - traditionally `config.cache'. FILE defaults to `/dev/null' to - disable caching. - -`--config-cache' -`-C' - Alias for `--cache-file=config.cache'. - -`--quiet' -`--silent' -`-q' - Do not print messages saying which checks are being made. To - suppress all normal output, redirect it to `/dev/null' (any error - messages will still be shown). - -`--srcdir=DIR' - Look for the package's source code in directory DIR. Usually - `configure' can determine that directory automatically. - -`configure' also accepts some other, not widely useful, options. Run -`configure --help' for more details. - diff --git a/Build/source/libs/pixman/pixman-0.30.0/Makefile.am b/Build/source/libs/pixman/pixman-0.30.0/Makefile.am deleted file mode 100644 index 5137c9ea306..00000000000 --- a/Build/source/libs/pixman/pixman-0.30.0/Makefile.am +++ /dev/null @@ -1,137 +0,0 @@ -SUBDIRS = pixman demos test - -pkgconfigdir=$(libdir)/pkgconfig -pkgconfig_DATA=pixman-1.pc - -$(pkgconfig_DATA): pixman-1.pc.in - -snapshot: - distdir="$(distdir)-`date '+%Y%m%d'`"; \ - test -d "$(srcdir)/.git" && distdir=$$distdir-`cd "$(srcdir)" && git rev-parse HEAD | cut -c 1-6`; \ - $(MAKE) $(AM_MAKEFLAGS) distdir="$$distdir" dist - -GPGKEY=3892336E -USERNAME=$$USER -RELEASE_OR_SNAPSHOT = $$(if test "x$(PIXMAN_VERSION_MINOR)" = "x$$(echo "$(PIXMAN_VERSION_MINOR)/2*2" | bc)" ; then echo release; else echo snapshot; fi) -RELEASE_CAIRO_HOST = $(USERNAME)@cairographics.org -RELEASE_CAIRO_DIR = /srv/cairo.freedesktop.org/www/$(RELEASE_OR_SNAPSHOT)s -RELEASE_CAIRO_URL = http://cairographics.org/$(RELEASE_OR_SNAPSHOT)s -RELEASE_XORG_URL = http://xorg.freedesktop.org/archive/individual/lib -RELEASE_XORG_HOST = $(USERNAME)@xorg.freedesktop.org -RELEASE_XORG_DIR = /srv/xorg.freedesktop.org/archive/individual/lib -RELEASE_ANNOUNCE_LIST = cairo-announce@cairographics.org, xorg-announce@lists.freedesktop.org, pixman@lists.freedesktop.org - -EXTRA_DIST = \ - Makefile.win32 \ - Makefile.win32.common - -tar_gz = $(PACKAGE)-$(VERSION).tar.gz -tar_bz2 = $(PACKAGE)-$(VERSION).tar.bz2 - -sha1_tgz = $(tar_gz).sha1 -md5_tgz = $(tar_gz).md5 - -sha1_tbz2 = $(tar_bz2).sha1 -md5_tbz2 = $(tar_bz2).md5 - -gpg_file = $(sha1_tgz).asc - -$(sha1_tgz): $(tar_gz) - sha1sum $^ > $@ - -$(md5_tgz): $(tar_gz) - md5sum $^ > $@ - -$(sha1_tbz2): $(tar_bz2) - sha1sum $^ > $@ - -$(md5_tbz2): $(tar_bz2) - md5sum $^ > $@ - -$(gpg_file): $(sha1_tgz) - @echo "Please enter your GPG password to sign the checksum." - gpg --armor --sign $^ - -HASHFILES = $(sha1_tgz) $(sha1_tbz2) $(md5_tgz) $(md5_tbz2) - -release-verify-newer: - @echo -n "Checking that no $(VERSION) release already exists at $(RELEASE_XORG_HOST)..." - @ssh $(RELEASE_XORG_HOST) test ! -e $(RELEASE_XORG_DIR)/$(tar_gz) \ - || (echo "Ouch." && echo "Found: $(RELEASE_XORG_HOST):$(RELEASE_XORG_DIR)/$(tar_gz)" \ - && echo "Refusing to try to generate a new release of the same name." \ - && false) - @ssh $(RELEASE_CAIRO_HOST) test ! -e $(RELEASE_CAIRO_DIR)/$(tar_gz) \ - || (echo "Ouch." && echo "Found: $(RELEASE_CAIRO_HOST):$(RELEASE_CAIRO_DIR)/$(tar_gz)" \ - && echo "Refusing to try to generate a new release of the same name." \ - && false) - @echo "Good." - -release-remove-old: - $(RM) $(tar_gz) $(tar_bz2) $(HASHFILES) $(gpg_file) - -ensure-prev: - @if [[ "$(PREV)" == "" ]]; then \ - echo "" && \ - echo "You must set the PREV variable on the make command line to" && \ - echo "the last version." && \ - echo "" && \ - echo "For example:" && \ - echo " make PREV=0.7.3" && \ - echo "" && \ - false; \ - fi - -release-check: ensure-prev release-verify-newer release-remove-old distcheck - -release-tag: - git tag -u $(GPGKEY) -m "$(PACKAGE) $(VERSION) release" $(PACKAGE)-$(VERSION) - -release-upload: release-check $(tar_gz) $(tar_bz2) $(sha1_tgz) $(sha1_tbz2) $(md5_tgz) $(gpg_file) - scp $(tar_gz) $(sha1_tgz) $(gpg_file) $(RELEASE_CAIRO_HOST):$(RELEASE_CAIRO_DIR) - scp $(tar_gz) $(tar_bz2) $(RELEASE_XORG_HOST):$(RELEASE_XORG_DIR) - ssh $(RELEASE_CAIRO_HOST) "rm -f $(RELEASE_CAIRO_DIR)/LATEST-$(PACKAGE)-[0-9]* && ln -s $(tar_gz) $(RELEASE_CAIRO_DIR)/LATEST-$(PACKAGE)-$(VERSION)" - -RELEASE_TYPE = $$(if test "x$(PIXMAN_VERSION_MINOR)" = "x$$(echo "$(PIXMAN_VERSION_MINOR)/2*2" | bc)" ; then echo "stable release in the" ; else echo "development snapshot leading up to a stable"; fi) - -release-publish-message: $(HASHFILES) ensure-prev - @echo "Please follow the instructions in RELEASING to push stuff out and" - @echo "send out the announcement mails.

Function fast_composite_over_8888_0565 - * from pixman-fast-path.c does the same in C and can be used as a reference. - * - * First we need to have some NEON assembly code which can do the actual - * operation on the pixels and provide it to the template macro. - * - * Template macro quite conveniently takes care of emitting all the necessary - * code for memory reading and writing (including quite tricky cases of - * handling unaligned leading/trailing pixels), so we only need to deal with - * the data in NEON registers. - * - * NEON registers allocation in general is recommented to be the following: - * d0, d1, d2, d3 - contain loaded source pixel data - * d4, d5, d6, d7 - contain loaded destination pixels (if they are needed) - * d24, d25, d26, d27 - contain loading mask pixel data (if mask is used) - * d28, d29, d30, d31 - place for storing the result (destination pixels) - * - * As can be seen above, four 64-bit NEON registers are used for keeping - * intermediate pixel data and up to 8 pixels can be processed in one step - * for 32bpp formats (16 pixels for 16bpp, 32 pixels for 8bpp). - * - * This particular function uses the following registers allocation: - * d0, d1, d2, d3 - contain loaded source pixel data - * d4, d5 - contain loaded destination pixels (they are needed) - * d28, d29 - place for storing the result (destination pixels) - */ - -/* - * Step one. We need to have some code to do some arithmetics on pixel data. - * This is implemented as a pair of macros: '*_head' and '*_tail'. When used - * back-to-back, they take pixel data from {d0, d1, d2, d3} and {d4, d5}, - * perform all the needed calculations and write the result to {d28, d29}. - * The rationale for having two macros and not just one will be explained - * later. In practice, any single monolitic function which does the work can - * be split into two parts in any arbitrary way without affecting correctness. - * - * There is one special trick here too. Common template macro can optionally - * make our life a bit easier by doing R, G, B, A color components - * deinterleaving for 32bpp pixel formats (and this feature is used in - * 'pixman_composite_over_8888_0565_asm_neon' function). So it means that - * instead of having 8 packed pixels in {d0, d1, d2, d3} registers, we - * actually use d0 register for blue channel (a vector of eight 8-bit - * values), d1 register for green, d2 for red and d3 for alpha. This - * simple conversion can be also done with a few NEON instructions: - * - * Packed to planar conversion: - * vuzp.8 d0, d1 - * vuzp.8 d2, d3 - * vuzp.8 d1, d3 - * vuzp.8 d0, d2 - * - * Planar to packed conversion: - * vzip.8 d0, d2 - * vzip.8 d1, d3 - * vzip.8 d2, d3 - * vzip.8 d0, d1 - * - * But pixel can be loaded directly in planar format using VLD4.8 NEON - * instruction. It is 1 cycle slower than VLD1.32, so this is not always - * desirable, that's why deinterleaving is optional. - * - * But anyway, here is the code: - */ -.macro pixman_composite_over_8888_0565_process_pixblock_head - /* convert 8 r5g6b5 pixel data from {d4, d5} to planar 8-bit format - and put data into d6 - red, d7 - green, d30 - blue */ - vshrn.u16 d6, q2, #8 - vshrn.u16 d7, q2, #3 - vsli.u16 q2, q2, #5 - vsri.u8 d6, d6, #5 - vmvn.8 d3, d3 /* invert source alpha */ - vsri.u8 d7, d7, #6 - vshrn.u16 d30, q2, #2 - /* now do alpha blending, storing results in 8-bit planar format - into d16 - red, d19 - green, d18 - blue */ - vmull.u8 q10, d3, d6 - vmull.u8 q11, d3, d7 - vmull.u8 q12, d3, d30 - vrshr.u16 q13, q10, #8 - vrshr.u16 q3, q11, #8 - vrshr.u16 q15, q12, #8 - vraddhn.u16 d20, q10, q13 - vraddhn.u16 d23, q11, q3 - vraddhn.u16 d22, q12, q15 -.endm - -.macro pixman_composite_over_8888_0565_process_pixblock_tail - /* ... continue alpha blending */ - vqadd.u8 d16, d2, d20 - vqadd.u8 q9, q0, q11 - /* convert the result to r5g6b5 and store it into {d28, d29} */ - vshll.u8 q14, d16, #8 - vshll.u8 q8, d19, #8 - vshll.u8 q9, d18, #8 - vsri.u16 q14, q8, #5 - vsri.u16 q14, q9, #11 -.endm - -/* - * OK, now we got almost everything that we need. Using the above two - * macros, the work can be done right. But now we want to optimize - * it a bit. ARM Cortex-A8 is an in-order core, and benefits really - * a lot from good code scheduling and software pipelining. - * - * Let's construct some code, which will run in the core main loop. - * Some pseudo-code of the main loop will look like this: - * head - * while (...) { - * tail - * head - * } - * tail - * - * It may look a bit weird, but this setup allows to hide instruction - * latencies better and also utilize dual-issue capability more - * efficiently (make pairs of load-store and ALU instructions). - * - * So what we need now is a '*_tail_head' macro, which will be used - * in the core main loop. A trivial straightforward implementation - * of this macro would look like this: - * - * pixman_composite_over_8888_0565_process_pixblock_tail - * vst1.16 {d28, d29}, [DST_W, :128]! - * vld1.16 {d4, d5}, [DST_R, :128]! - * vld4.32 {d0, d1, d2, d3}, [SRC]! - * pixman_composite_over_8888_0565_process_pixblock_head - * cache_preload 8, 8 - * - * Now it also got some VLD/VST instructions. We simply can't move from - * processing one block of pixels to the other one with just arithmetics. - * The previously processed data needs to be written to memory and new - * data needs to be fetched. Fortunately, this main loop does not deal - * with partial leading/trailing pixels and can load/store a full block - * of pixels in a bulk. Additionally, destination buffer is already - * 16 bytes aligned here (which is good for performance). - * - * New things here are DST_R, DST_W, SRC and MASK identifiers. These - * are the aliases for ARM registers which are used as pointers for - * accessing data. We maintain separate pointers for reading and writing - * destination buffer (DST_R and DST_W). - * - * Another new thing is 'cache_preload' macro. It is used for prefetching - * data into CPU L2 cache and improve performance when dealing with large - * images which are far larger than cache size. It uses one argument - * (actually two, but they need to be the same here) - number of pixels - * in a block. Looking into 'pixman-arm-neon-asm.h' can provide some - * details about this macro. Moreover, if good performance is needed - * the code from this macro needs to be copied into '*_tail_head' macro - * and mixed with the rest of code for optimal instructions scheduling. - * We are actually doing it below. - * - * Now after all the explanations, here is the optimized code. - * Different instruction streams (originaling from '*_head', '*_tail' - * and 'cache_preload' macro) use different indentation levels for - * better readability. Actually taking the code from one of these - * indentation levels and ignoring a few VLD/VST instructions would - * result in exactly the code from '*_head', '*_tail' or 'cache_preload' - * macro! - */ - -#if 1 - -.macro pixman_composite_over_8888_0565_process_pixblock_tail_head - vqadd.u8 d16, d2, d20 - vld1.16 {d4, d5}, [DST_R, :128]! - vqadd.u8 q9, q0, q11 - vshrn.u16 d6, q2, #8 - fetch_src_pixblock - vshrn.u16 d7, q2, #3 - vsli.u16 q2, q2, #5 - vshll.u8 q14, d16, #8 - PF add PF_X, PF_X, #8 - vshll.u8 q8, d19, #8 - PF tst PF_CTL, #0xF - vsri.u8 d6, d6, #5 - PF addne PF_X, PF_X, #8 - vmvn.8 d3, d3 - PF subne PF_CTL, PF_CTL, #1 - vsri.u8 d7, d7, #6 - vshrn.u16 d30, q2, #2 - vmull.u8 q10, d3, d6 - PF pld, [PF_SRC, PF_X, lsl #src_bpp_shift] - vmull.u8 q11, d3, d7 - vmull.u8 q12, d3, d30 - PF pld, [PF_DST, PF_X, lsl #dst_bpp_shift] - vsri.u16 q14, q8, #5 - PF cmp PF_X, ORIG_W - vshll.u8 q9, d18, #8 - vrshr.u16 q13, q10, #8 - PF subge PF_X, PF_X, ORIG_W - vrshr.u16 q3, q11, #8 - vrshr.u16 q15, q12, #8 - PF subges PF_CTL, PF_CTL, #0x10 - vsri.u16 q14, q9, #11 - PF ldrgeb DUMMY, [PF_SRC, SRC_STRIDE, lsl #src_bpp_shift]! - vraddhn.u16 d20, q10, q13 - vraddhn.u16 d23, q11, q3 - PF ldrgeb DUMMY, [PF_DST, DST_STRIDE, lsl #dst_bpp_shift]! - vraddhn.u16 d22, q12, q15 - vst1.16 {d28, d29}, [DST_W, :128]! -.endm - -#else - -/* If we did not care much about the performance, we would just use this... */ -.macro pixman_composite_over_8888_0565_process_pixblock_tail_head - pixman_composite_over_8888_0565_process_pixblock_tail - vst1.16 {d28, d29}, [DST_W, :128]! - vld1.16 {d4, d5}, [DST_R, :128]! - fetch_src_pixblock - pixman_composite_over_8888_0565_process_pixblock_head - cache_preload 8, 8 -.endm - -#endif - -/* - * And now the final part.

A Region is simply a set of disjoint - * (non-overlapping) rectangles, plus an "extent" rectangle which is the - * smallest single rectangle that contains all the non-overlapping rectangles. - * - * A Region is implemented as a "y-x-banded" array of rectangles. This array - * imposes two degrees of order. First, all rectangles are sorted by top side - * y coordinate first (y1), and then by left side x coordinate (x1). - * - * Furthermore, the rectangles are grouped into "bands". Each rectangle in a - * band has the same top y coordinate (y1), and each has the same bottom y - * coordinate (y2). Thus all rectangles in a band differ only in their left - * and right side (x1 and x2). Bands are implicit in the array of rectangles: - * there is no separate list of band start pointers. - * - * The y-x band representation does not minimize rectangles. In particular, - * if a rectangle vertically crosses a band (the rectangle has scanlines in - * the y1 to y2 area spanned by the band), then the rectangle may be broken - * down into two or more smaller rectangles stacked one atop the other. - * - * ----------- ----------- - * | | | | band 0 - * | | -------- ----------- -------- - * | | | | in y-x banded | | | | band 1 - * | | | | form is | | | | - * ----------- | | ----------- -------- - * | | | | band 2 - * -------- -------- - * - * An added constraint on the rectangles is that they must cover as much - * horizontal area as possible: no two rectangles within a band are allowed - * to touch. - * - * Whenever possible, bands will be merged together to cover a greater vertical - * distance (and thus reduce the number of rectangles). Two bands can be merged - * only if the bottom of one touches the top of the other and they have - * rectangles in the same places (of the same width, of course). - * - * Adam de Boor wrote most of the original region code. Joel McCormack - * substantially modified or rewrote most of the core arithmetic routines, and - * added pixman_region_validate in order to support several speed improvements - * to pixman_region_validate_tree. Bob Scheifler changed the representation - * to be more compact when empty or a single rectangle, and did a bunch of - * gratuitous reformatting. Carl Worth did further gratuitous reformatting - * while re-merging the server and client region code into libpixregion. - * Soren Sandmann did even more gratuitous reformatting. - */ - -/* true iff two Boxes overlap */ -#define EXTENTCHECK(r1, r2) \ - (!( ((r1)->x2 <= (r2)->x1) || \ - ((r1)->x1 >= (r2)->x2) || \ - ((r1)->y2 <= (r2)->y1) || \ - ((r1)->y1 >= (r2)->y2) ) ) - -/* true iff (x,y) is in Box */ -#define INBOX(r, x, y) \ - ( ((r)->x2 > x) && \ - ((r)->x1 <= x) && \ - ((r)->y2 > y) && \ - ((r)->y1 <= y) ) - -/* true iff Box r1 contains Box r2 */ -#define SUBSUMES(r1, r2) \ - ( ((r1)->x1 <= (r2)->x1) && \ - ((r1)->x2 >= (r2)->x2) && \ - ((r1)->y1 <= (r2)->y1) && \ - ((r1)->y2 >= (r2)->y2) ) - -static size_t -PIXREGION_SZOF (size_t n) -{ - size_t size = n * sizeof(box_type_t);

The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + +You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/Build/source/libs/pixman/pixman-0.30.2/Makefile.am b/Build/source/libs/pixman/pixman-0.30.2/Makefile.am new file mode 100644 index 00000000000..5137c9ea306 --- /dev/null +++ b/Build/source/libs/pixman/pixman-0.30.2/Makefile.am @@ -0,0 +1,137 @@ +SUBDIRS = pixman demos test + +pkgconfigdir=$(libdir)/pkgconfig +pkgconfig_DATA=pixman-1.pc + +$(pkgconfig_DATA): pixman-1.pc.in + +snapshot: + distdir="$(distdir)-`date '+%Y%m%d'`"; \ + test -d "$(srcdir)/.git" && distdir=$$distdir-`cd "$(srcdir)" && git rev-parse HEAD | cut -c 1-6`; \ + $(MAKE) $(AM_MAKEFLAGS) distdir="$$distdir" dist + +GPGKEY=3892336E +USERNAME=$$USER +RELEASE_OR_SNAPSHOT = $$(if test "x$(PIXMAN_VERSION_MINOR)" = "x$$(echo "$(PIXMAN_VERSION_MINOR)/2*2" | bc)" ; then echo release; else echo snapshot; fi) +RELEASE_CAIRO_HOST = $(USERNAME)@cairographics.org +RELEASE_CAIRO_DIR = /srv/cairo.freedesktop.org/www/$(RELEASE_OR_SNAPSHOT)s +RELEASE_CAIRO_URL = http://cairographics.org/$(RELEASE_OR_SNAPSHOT)s +RELEASE_XORG_URL = http://xorg.freedesktop.org/archive/individual/lib +RELEASE_XORG_HOST = $(USERNAME)@xorg.freedesktop.org +RELEASE_XORG_DIR = /srv/xorg.freedesktop.org/archive/individual/lib +RELEASE_ANNOUNCE_LIST = cairo-announce@cairographics.org, xorg-announce@lists.freedesktop.org, pixman@lists.freedesktop.org + +EXTRA_DIST = \ + Makefile.win32 \ + Makefile.win32.common + +tar_gz = $(PACKAGE)-$(VERSION).tar.gz +tar_bz2 = $(PACKAGE)-$(VERSION).tar.bz2 + +sha1_tgz = $(tar_gz).sha1 +md5_tgz = $(tar_gz).md5 + +sha1_tbz2 = $(tar_bz2).sha1 +md5_tbz2 = $(tar_bz2).md5 + +gpg_file = $(sha1_tgz).asc + +$(sha1_tgz): $(tar_gz) + sha1sum $^ > $@ + +$(md5_tgz): $(tar_gz) + md5sum $^ > $@ + +$(sha1_tbz2): $(tar_bz2) + sha1sum $^ > $@ + +$(md5_tbz2): $(tar_bz2) + md5sum $^ > $@ + +$(gpg_file): $(sha1_tgz) + @echo "Please enter your GPG password to sign the checksum." + gpg --armor --sign $^ + +HASHFILES = $(sha1_tgz) $(sha1_tbz2) $(md5_tgz) $(md5_tbz2) + +release-verify-newer: + @echo -n "Checking that no $(VERSION) release already exists at $(RELEASE_XORG_HOST)..." + @ssh $(RELEASE_XORG_HOST) test ! -e $(RELEASE_XORG_DIR)/$(tar_gz) \ + || (echo "Ouch." && echo "Found: $(RELEASE_XORG_HOST):$(RELEASE_XORG_DIR)/$(tar_gz)" \ + && echo "Refusing to try to generate a new release of the same name." \ + && false) + @ssh $(RELEASE_CAIRO_HOST) test ! -e $(RELEASE_CAIRO_DIR)/$(tar_gz) \ + || (echo "Ouch." && echo "Found: $(RELEASE_CAIRO_HOST):$(RELEASE_CAIRO_DIR)/$(tar_gz)" \ + && echo "Refusing to try to generate a new release of the same name." \ + && false) + @echo "Good." + +release-remove-old: + $(RM) $(tar_gz) $(tar_bz2) $(HASHFILES) $(gpg_file) + +ensure-prev: + @if [[ "$(PREV)" == "" ]]; then \ + echo "" && \ + echo "You must set the PREV variable on the make command line to" && \ + echo "the last version." && \ + echo "" && \ + echo "For example:" && \ + echo " make PREV=0.7.3" && \ + echo "" && \ + false; \ + fi + +release-check: ensure-prev release-verify-newer release-remove-old distcheck + +release-tag: + git tag -u $(GPGKEY) -m "$(PACKAGE) $(VERSION) release" $(PACKAGE)-$(VERSION) + +release-upload: release-check $(tar_gz) $(tar_bz2) $(sha1_tgz) $(sha1_tbz2) $(md5_tgz) $(gpg_file) + scp $(tar_gz) $(sha1_tgz) $(gpg_file) $(RELEASE_CAIRO_HOST):$(RELEASE_CAIRO_DIR) + scp $(tar_gz) $(tar_bz2) $(RELEASE_XORG_HOST):$(RELEASE_XORG_DIR) + ssh $(RELEASE_CAIRO_HOST) "rm -f $(RELEASE_CAIRO_DIR)/LATEST-$(PACKAGE)-[0-9]* && ln -s $(tar_gz) $(RELEASE_CAIRO_DIR)/LATEST-$(PACKAGE)-$(VERSION)" + +RELEASE_TYPE = $$(if test "x$(PIXMAN_VERSION_MINOR)" = "x$$(echo "$(PIXMAN_VERSION_MINOR)/2*2" | bc)" ; then echo "stable release in the" ; else echo "development snapshot leading up to a stable"; fi) + +release-publish-message: $(HASHFILES) ensure-prev + @echo "Please follow the instructions in RELEASING to push stuff out and" + @echo "send out the announcement mails.

In this case, make one commit that makes the + test suite fail due to the bug, and then another commit that fixes + the bug. + + You can run the test suite with + + make check + + It will take around two minutes to run on a modern PC. + + - Follow the coding style described in the CODING_STYLE file + + - For bug fixes, include an update to the test suite to make sure + the bug doesn't reappear. + + - For new features, add tests of the feature to the test + suite. Also, add a program demonstrating the new feature to the + demos/ directory. + + - Write descriptive commit messages. Useful information to include: + - Benchmark results, before and after + - Description of the bug that was fixed + - Detailed rationale for any new API + - Alternative approaches that were rejected (and why they + don't work) + - If review comments were incorporated, a brief version + history describing what those changes were. + + - For big patch series, send an introductory email with an overall + description of the patch series, including benchmarks and + motivation. Each commit message should still be descriptive and + include enough information to understand why this particular commit + was necessary. + +Pixman has high standards for code quality and so almost everybody +should expect to have the first versions of their patches rejected. + +If you think that the reviewers are wrong about something, or that the +guidelines above are wrong, feel free to discuss the issue on the +list.

We need to have some code to do some arithmetics on pixel data. + * This is implemented as a pair of macros: '*_head' and '*_tail'. When used + * back-to-back, they take pixel data from {d0, d1, d2, d3} and {d4, d5}, + * perform all the needed calculations and write the result to {d28, d29}. + * The rationale for having two macros and not just one will be explained + * later. In practice, any single monolitic function which does the work can + * be split into two parts in any arbitrary way without affecting correctness. + * + * There is one special trick here too. Common template macro can optionally + * make our life a bit easier by doing R, G, B, A color components + * deinterleaving for 32bpp pixel formats (and this feature is used in + * 'pixman_composite_over_8888_0565_asm_neon' function).

ARM Cortex-A8 is an in-order core, and benefits really + * a lot from good code scheduling and software pipelining. + * + * Let's construct some code, which will run in the core main loop. + * Some pseudo-code of the main loop will look like this: + * head + * while (...) { + * tail + * head + * } + * tail + * + * It may look a bit weird, but this setup allows to hide instruction + * latencies better and also utilize dual-issue capability more + * efficiently (make pairs of load-store and ALU instructions). + * + * So what we need now is a '*_tail_head' macro, which will be used + * in the core main loop. A trivial straightforward implementation + * of this macro would look like this: + * + * pixman_composite_over_8888_0565_process_pixblock_tail + * vst1.16 {d28, d29}, [DST_W, :128]! + * vld1.16 {d4, d5}, [DST_R, :128]! + * vld4.32 {d0, d1, d2, d3}, [SRC]! + * pixman_composite_over_8888_0565_process_pixblock_head + * cache_preload 8, 8 + * + * Now it also got some VLD/VST instructions. We simply can't move from + * processing one block of pixels to the other one with just arithmetics. + * The previously processed data needs to be written to memory and new + * data needs to be fetched. Fortunately, this main loop does not deal + * with partial leading/trailing pixels and can load/store a full block + * of pixels in a bulk. Additionally, destination buffer is already + * 16 bytes aligned here (which is good for performance). + * + * New things here are DST_R, DST_W, SRC and MASK identifiers. These + * are the aliases for ARM registers which are used as pointers for + * accessing data. We maintain separate pointers for reading and writing + * destination buffer (DST_R and DST_W). + * + * Another new thing is 'cache_preload' macro. It is used for prefetching + * data into CPU L2 cache and improve performance when dealing with large + * images which are far larger than cache size. It uses one argument + * (actually two, but they need to be the same here) - number of pixels + * in a block. Looking into 'pixman-arm-neon-asm.h' can provide some + * details about this macro. Moreover, if good performance is needed + * the code from this macro needs to be copied into '*_tail_head' macro + * and mixed with the rest of code for optimal instructions scheduling. + * We are actually doing it below. + * + * Now after all the explanations, here is the optimized code. + * Different instruction streams (originaling from '*_head', '*_tail' + * and 'cache_preload' macro) use different indentation levels for + * better readability.

This is a macro for implementing cache preload.

Prefetch distance is + * handled in an 'incremental' way: it starts from 0 and advances to the + * optimal distance over time. After reaching optimal prefetch distance, + * it is kept constant. There are some checks which prevent prefetching + * unneeded pixel lines below the image (but it still can prefetch a bit + * more data on the right side of the image - not a big issue and may + * be actually helpful when rendering text glyphs). Additional trick is + * the use of LDR instruction for prefetch instead of PLD when moving to + * the next line, the point is that we have a high chance of getting TLB + * miss in this case, and PLD would be useless. + * + * This sounds like it may introduce a noticeable overhead (when working with + * fully cached data). But in reality, due to having a separate pipeline and + * instruction queue for NEON unit in ARM Cortex-A8, normal ARM code can + * execute simultaneously with NEON and be completely shadowed by it. Thus + * we get no performance overhead at all (*). This looks like a very nice + * feature of Cortex-A8, if used wisely. We don't have a hardware prefetcher, + * but still can implement some rather advanced prefetch logic in software + * for almost zero cost! + * + * (*) The overhead of the prefetcher is visible when running some trivial + * pixels processing like simple copy.

When a pixel row is long enough, there + * are three distinct phases of prefetch: + * * an inner loop section, where each time a cacheline of data is + * processed, another cacheline is preloaded (the exact distance ahead is + * determined empirically using profiling results from lowlevel-blt-bench) + * * a leading section, where enough cachelines are preloaded to ensure no + * cachelines escape being preloaded when the inner loop starts + * * a trailing section, where a limited number (0 or more) of cachelines + * are preloaded to deal with data (if any) that hangs off the end of the + * last iteration of the inner loop, plus any trailing bytes that were not + * enough to make up one whole iteration of the inner loop + * + * There are (in general) three distinct code paths, selected between + * depending upon how long the pixel row is. If it is long enough that there + * is at least one iteration of the inner loop (as described above) then + * this is described as the "wide" case. If it is shorter than that, but + * there are still enough bytes output that there is at least one 16-byte- + * long, 16-byte-aligned write to the destination (the optimum type of + * write), then this is the "medium" case.

A Region is simply a set of disjoint + * (non-overlapping) rectangles, plus an "extent" rectangle which is the + * smallest single rectangle that contains all the non-overlapping rectangles. + * + * A Region is implemented as a "y-x-banded" array of rectangles. This array + * imposes two degrees of order. First, all rectangles are sorted by top side + * y coordinate first (y1), and then by left side x coordinate (x1). + * + * Furthermore, the rectangles are grouped into "bands". Each rectangle in a + * band has the same top y coordinate (y1), and each has the same bottom y + * coordinate (y2). Thus all rectangles in a band differ only in their left + * and right side (x1 and x2). Bands are implicit in the array of rectangles: + * there is no separate list of band start pointers. + * + * The y-x band representation does not minimize rectangles. In particular, + * if a rectangle vertically crosses a band (the rectangle has scanlines in + * the y1 to y2 area spanned by the band), then the rectangle may be broken + * down into two or more smaller rectangles stacked one atop the other. + * + * ----------- ----------- + * | | | | band 0 + * | | -------- ----------- -------- + * | | | | in y-x banded | | | | band 1 + * | | | | form is | | | | + * ----------- | | ----------- -------- + * | | | | band 2 + * -------- -------- + * + * An added constraint on the rectangles is that they must cover as much + * horizontal area as possible: no two rectangles within a band are allowed + * to touch. + * + * Whenever possible, bands will be merged together to cover a greater vertical + * distance (and thus reduce the number of rectangles). Two bands can be merged + * only if the bottom of one touches the top of the other and they have + * rectangles in the same places (of the same width, of course). + * + * Adam de Boor wrote most of the original region code. Joel McCormack + * substantially modified or rewrote most of the core arithmetic routines, and + * added pixman_region_validate in order to support several speed improvements + * to pixman_region_validate_tree. Bob Scheifler changed the representation + * to be more compact when empty or a single rectangle, and did a bunch of + * gratuitous reformatting.
