i686: Fix multiple definitions of __memmove_chk and __memset_chk
|
|
|
|
Commit c73c96a4a1af1326df7f96eec58209e1e04066d8 updated memcpy.S and
|
|
mempcpy.S, but omitted memmove.S and memset.S. As a result, the static
|
|
library built as PIC, whether with or without multiarch support,
|
|
contains two definitions for each of the __memmove_chk and __memset_chk
|
|
symbols.

/usr/lib/gcc/i686-pc-linux-gnu/14/../../../../i686-pc-linux-gnu/bin/ld: /usr/lib/gcc/i686-pc-linux-gnu/14/../../../../lib/libc.a(memset-ia32.o): in function `__memset_chk':

/var/tmp/portage/sys-libs/glibc-2.39-r3/work/glibc-2.39/string/../sysdeps/i386/i686/memset.S:32: multiple definition of `__memset_chk'; /usr/lib/gcc/i686-pc-linux-gnu/14/../../../../lib/libc.a(memset_chk.o):/var/tmp/portage/sys-libs/glibc-2.39-r3/work/glibc-2.39/debug/../sysdeps/i386/i686/multiarch/memset_chk.c:24: first defined here
|
|
|
|
After this change, regardless of PIC options, the static library, built
|
|
for i686 with multiarch contains implementations of these functions
|
|
respectively from debug/memmove_chk.c and debug/memset_chk.c, and
|
|
without multiarch contains implementations of these functions
|
|
respectively from sysdeps/i386/memmove_chk.S and
|
|
sysdeps/i386/memset_chk.S. This ensures that memmove and memset won't
|
|
pull in __chk_fail and the routines it calls.
