Revision 1.11.6.1, Mon Feb 27 20:22:59 2012 UTC (12 years, 1 month ago) by riz
Pull up following revision(s) (requested by joerg in ticket #57): lib/libc/arch/arm/sys/cerror.S: revision 1.8 lib/libc/arch/vax/SYS.h: revision 1.12 lib/libc/arch/powerpc64/sys/cerror.S: revision 1.3 lib/libc/arch/powerpc64/sys/cerror.S: revision 1.4 lib/libc/arch/i386/sys/cerror.S: revision 1.16 lib/libc/arch/x86_64/sys/cerror.S: revision 1.5 lib/libc/arch/powerpc/sys/cerror.S: revision 1.10 lib/libc/arch/mips/sys/cerror.S: revision 1.17 lib/libc/arch/powerpc/sys/cerror.S: revision 1.9 Make __cerror protected to restore ABI leak in older libc versions, where e.g. librt referenced the copy from libc. This still allows libc to use PC-relative jumps. PowerPC doesn't have CERROR since it never had a.out. Use _C_LABEL(__cerror) instead. |
