[PATCH 10/15] Link a non-libc-using test with -fno-stack-protector.

Nix nix@esperi.org.uk
Mon Dec 19 11:25:00 GMT 2016


From: Nick Alcock <nick.alcock@oracle.com>

This test cannot see __stack_chk_fail() because it is not linked with
libc at all.

v3: Use $(no-stack-protector).
v10: Drop a bunch of tests that don't need this option.

	* elf/Makefile (CFLAGS-filtmod1.c): Use $(no-stack-protector) for
	non-libc-linking testcase.
