The following patch works around quite a number of i386 testcases
FAILing on Solaris/x86, as reported in the PR. To avoid tons of
testsuite noise, the following patch adds -mno-stackrealign to the
affected testcases and will thus benefit other targets that default to
-mstackrealign, too.
Bootstrapped without regressions on i386-pc-solaris2.12 and
x86_64-pc-linux-gnuu (both multilibs in each case).
Ok for mainline and (eventually) the gcc-6 branch?
Thanks.
Rainer
