Hello all,
I recently recognized that we run the libffi testsuite without any gcc
flags like -Ox or so. This had the effect that a test case was failing
since it fell in the area of PR 323. return_fl2.c was compiled with -O0.
Now my question, would it make sense to run the testsuite with different
opt flags like -O0, -O2 ...?
The ABI should stay the same over all opt flags, yes, but real life apps
usually use -O2 right?
It could be done easily by just running the suite again with a different
set.
(I used -W -Wall to clean up the test cases from warnings, a patch which
will follow soon)
Comments?
I think it is an excellent idea. I for one normally use -O3 (not -O2).
But testing with both -O0 and -O[s23] makes a lot of sense to me.
