simon at pushface dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |simon at pushface dot org --- Comment #4 from simon at pushface dot org --- I’ve found the same 9 fails as Eric on x86_64-apple-darwin15 with -flto -O2. I can’t try with -flto -O2 -g because of pr 83960. Please note that I’ve been working on ACATS 4.1f (the latest version, rather than the 15-year-old version 2.5 currently in GCC), hoping to get it included in GCC at some stage, see https://github.com/simonjwright/ACATS; I’ve just checked in a change so that you can say for example make check-acats gccflags='-O2 -g -flto' (gccflags is the variable name in the ACATS script) and I’m wondering whether I should choose a more specific name? e.g. ACATS_GCCFLAGS.
