From: "hanzac at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/24610] New: The comment start symbol of arm target Date: Tue, 01 Nov 2005 07:31:00 -0000 [thread overview] Message-ID: <bug-24610-11002@http.gcc.gnu.org/bugzilla/> (raw) It's true that the arm comment start symbol is '@', but GCC will generate some assembler code end with a '@' and a comment without a separator so it can't be parsed by gas. For example, I compile the libgcc2.c:__gcc_bcmp with xgcc, it failed: _____________________________________________________________________ /* Like bcmp except the sign is meaningful. Result is negative if S1 is less than S2, positive if S1 is greater, 0 if S1 and S2 are equal. */ int __gcc_bcmp (const unsigned char *s1, const unsigned char *s2, size_t size) { while (size > 0) { const unsigned char c1 = *s1++, c2 = *s2++; if (c1 != c2) return c1 - c2; size--; } return 0; } _____________________________________________________________________ I'm compile gcc under cygwin and mingw32-gcc, binutils-2.16.1 already compiled also with --target=arm-wince-pe, here is the gcc(gcc-4.1-20051022) configuration: $ ./configure --disable-nls --disable-win32-registry --enable-threads=win32 --host=i686-pc-mingw32 --build=i686-pc-mingw32 --target=arm-wince-pe I also found that if I made a change in gcc-4.1-20051022\gcc\config\arm\aout.h (add a semicolon), it will work: @@ -294,7 +294,7 @@ #endif #ifndef ASM_COMMENT_START -#define ASM_COMMENT_START "@" +#define ASM_COMMENT_START ";@" #endif /* This works for GAS and some other assemblers. */ See also in: http://gcc.gnu.org/ml/gcc/2005-10/msg01215.html -- Summary: The comment start symbol of arm target Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: hanzac at gmail dot com GCC build triplet: i686-pc-mingw32 GCC host triplet: i686-pc-mingw32 GCC target triplet: arm-wince-pe http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24610
