On Cygwin, gas opens binary files with "r" instead of "rb".
This causes corruption when Cygwin is installed with CR/LF mode.
For example, the .incbin directive is broken :
$ cat bug.s
.incbin "fic.bin"
$ od -t x1 fic.bin
0000000 41 0d 0a 42
0000004
$ as bug.s -o bug.o
bug.s: Assembler messages:
bug.s:1: Warning: truncated file `fic.bin', 3 of 4 bytes read
$ objdump -s bug.o
bug.o: file format pe-i386
Contents of section .text:
0000 410a4242 90909090 90909090 90909090 A.BB............
It can easily be fixed in gas/as.h :
#ifndef FOPEN_WB
/* #if defined GO32 || defined __MINGW32__ */
#if defined GO32 || defined __MINGW32__ || defined __CYGWIN__
#include "fopen-bin.h"
#else
#include "fopen-same.h"
#endif
#endif
Can someone check in the above code ?
Note : It may be better to use something stronger like USE_BINARY_FOPEN like in
the file sysdep.h in bfd and ld.
