Description Mikhail Teterin freebsd_committer freebsd_triage 2016-04-30 20:09:27 UTC 
My CPUs do not SSE4, but Makefile generated by qt5-qmake have -msse4.2 prepended to CXXFLAGS anyway. The CFLAGS are Ok, but CXXFLAGS are overly aggressive, which causes some programs to die from SIGILL.

I'm not sure, what causes the flag to be added by mistake -- my regular CFLAGS (and CXXFLAGS) say:

   -O2 -pipe -march=core2  -fstack-protector -fno-strict-aliasing
Comment 1 Tobias C. Berner freebsd_committer freebsd_triage 2016-09-28 21:09:14 UTC 
Is this still relevant? And do you 'tweak' using make.conf (e.g. set CPUTYPE or other optimization relevant variables)?

Timeout, closing.
