Kir Kolyshkin 0367a1f6fe Drop prefix from own memcpy/memset/memcmp ... C compiler might generate calls to memcpy, memset, memcmp, and memmove as it seem fit (so far we haven't seen memmove being required). That means we need to provide our own versions of it for code which is not linked to a libc. We already have a solution for that in commit bdf6051 ("pie: provide memcpy/memcmp/memset for noglibc case") but we faced another problem of compiler trying to optimize our builtin_memset() by inserting calls to memset() which is just an alias in our case and so it lead to infinite recursion. This was workarounded in commit 8ea0ba7 ("string.h: fix memset over-optimization with clang") but it's not clear that was a proper fix. This patch is considered to be the real solution. As we don't have any other implementations of memset/memcpy/memcmp in non-libc case, we can call ours without any prefixes and avoid using weak aliases. Implementation notes: 1. mem*() functions code had to be moved from .h to .c for the functions to be compatible with their prototypes declared in /usr/include/string.h (i.e. "extern"). 2. FORTIFY_SOURCE needed to be disabled for code not linked to libc, because otherwise memcpy() may be replaced with a macro that expands to __memcpy_chk() which of course can't be resolved during linking. https://travis-ci.org/kolyshkin/criu/builds/198415449 Signed-off-by: Kir Kolyshkin <kir@openvz.org> Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>		2017-02-06 13:29:54 +03:00
