Subject: [PATCH] i686: Fix multiple definitions of __memmove_chk and __memset_chk
Date: Fri, 26 Apr 2024 10:50:00 +0000	[thread overview]
Message-ID: <20240426105001.699765-1-gabifalk@gmx.com> (raw)

Commit c73c96a4a1af1326df7f96eec58209e1e04066d8 updated memcpy.S and
mempcpy.S, but omitted memmove.S` and memset.S.  As a result, the
static library built with enabled multiarch (the default) 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
