Adhemerval Zanella	1c87f71a36	s390: Use dl-symbol-redir-ifunc.h on cpu-tunables ... Using the memcmp symbol directly allows the compile to inline the memcmp calls (especially because _dl_tunable_set_hwcaps uses constants values), generating better code. Checked with tst-tunables on s390x-linux-gnu (qemu system). Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>	2023-11-21 16:15:42 -03:00

Adhemerval Zanella	5355f9ca7b	elf: Remove -fno-tree-loop-distribute-patterns usage on dl-support ... Besides the option being gcc specific, this approach is still fragile and not future proof since we do not know if this will be the only optimization option gcc will add that transforms loops to memset (or any libcall). This patch adds a new header, dl-symbol-redir-ifunc.h, that can b used to redirect the compiler generated libcalls to port the generic memset implementation if required. Checked on x86_64-linux-gnu and aarch64-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com>	2022-10-10 10:32:28 -03:00
