* posix/bits/unistd.h: Avoid calling __*_chk variants if we can
determine the call will never trigger a failure. * sysdeps/i386/i686/memset_chk.S: Remove alias and warning. * sysdeps/x86_64/memset_chk.S: Likewise. 2005-02-24 Roland McGrath <roland@redhat.com> * debug/Versions (libc: GLIBC_2.4): Remove __memset_zero_constant_len_parameter. * sysdeps/generic/memset_chk.c: Remove alias and warning. * misc/sys/cdefs.h (__warndecl): New macro. * debug/warning-nop.c: New file. * string/bits/string3.h (memset): Call __warn_memset_zero_len with no arguments, instead of calling __memset_zero_constant_len_parameter. Use __warndecl for __warn_memset_zero_len. * debug/Makefile (routines): Add $(static-only-routines). (static-only-routines): New variable.
