Two computers of mine fail to compile gcc-7.3.1-r5 with -march=skylake.
- Intel(R) Xeon(R) CPU E3-1535M v5 @ 2.90GHz
- Intel(R) Xeon(R) CPU E3-1240 v5 @ 3.50GHz
epro subarch is intel64-skylake
make.conf has CFLAGS manually set to:
CFLAGS="-march=skylake -O2 -pipe"
I am not sure if this is a bug as Gentoo Safe CFLAGS says march should possibly better set to "native".
Previously building gcc-7.3.1-r3 succeded with the above settings.
