Subject: Add inhibit_stack_protector to ifuncmain9 [BZ #25680]
X-Git-Tag: upstream/2.34~832
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=03f42a56eb4e88601ebb334787c8198156197b29;p=platform%2Fupstream%2Fglibc.git

Add inhibit_stack_protector to ifuncmain9 [BZ #25680]

Enabling --enable-stack-protector=all causes the following tests to fail:

    FAIL: elf/ifuncmain9picstatic
    FAIL: elf/ifuncmain9static

Nick Alcock (who committed the stack protector code) marked the IFUNC
resolvers with inhibit_stack_protector when he done the original work and
suggested doing so again @ BZ #25680. This patch adds
inhibit_stack_protector to ifuncmain9.

After patch is applied, --enable-stack-protector=all does not fail the
above tests.
