Commit Message

Jeff Law April 20, 2018, 5:21 p.m. UTC 
Back in October I added dg-skip-if directives for a small number of
stack-clash tests which were sensitive to whether or not the stack
protector was enabled.

Those skips triggered on -fstack-protector.  That worked, but was
insufficient to DTRT for -fstack-protector-strong of
-fstack-protector-all.  This change uses -fstack-protector* to guard
those tests.

It also adds guards to some of the newer x86/x86_64 tests where the
stack protector changes the assembly code in annoying ways.

This is strictly a testsuite change.

Committed to the trunk.
