LIST of bugs in current version of my web2c. (Nov. 1990)
POINTERS Crashes on self-referencing structures, e.g.
type horse = ^cow ;
cow=record
log : horse;
(etc)
In C this must all be rewritten approx. as follows:
struct xyz {
xyz *log ;
(etc)
followed by
typedef struct xyz cow ;
typedef cow *horse ;
WITH statements. Fails because if you have an array of records,
W2C knows the component type of the array is a record, but not
what type of record it is.
Variant records. A simple translation fails because you have to
name all the intermediate places on the way down from top level.
For example:
codeobject = packed record
breadth: iword ;
case boolean of
true: (IMfont: byte ; IMchar: byte );
{Printers font and character}
false: (multi: iword) ;
end;
must be translated approx:
typedef struct {
iword breadth ;
union{
struct{
byte IMfont ;
byte IMchar ;
} XXA ;
iword multi ;
} XXB ;
} codeobject ;
Then if C is a codeobject, C.IMfont must be translated as
C.XXB.XXA.IMfont
