Hi!
In our distro builds, we test with
RUNTESTFLAGS='--target_board=unix\{,-fstack-protector-strong\}'
because SSP is something we use widely in the distribution.
4 new strub test FAIL with that option though, as can be
seen with a simple
make check-gcc check-g++
RUNTESTFLAGS='--target_board=unix\{,-fstack-protector-strong\} dg.exp=strub-O*'
- in particular, the expand dump
\[(\]call\[^\n\]*strub_leave.*\n\[(\]code_label
regexps see code_labels in there introduced for stack protector.
The following patch fixes it by using -fno-stack-protector for these
explicitly.
Tested on x86_64-linux, ok for trunk?

* c-c++-common/strub-O2fni.c: Add -fno-stack-protector to dg-options.
* c-c++-common/strub-O3fni.c: Likewise.
* c-c++-common/strub-Os.c: Likewise.
* c-c++-common/strub-Og.c: Likewise.
