CFLAGS assembly flags #32

Open ormorph opened 2 years ago

ormorph commented 2 years ago

Apha9 version. I noticed that the latest build has CFLAGS parameters in /etc/portage/make.conf. There is no -ftree-vectorize flag, it seems to work slower without it. Why is this compiler flag not enabled for the build now?

Are you basically wanting us to add additional compiler optimizations above and beyond the defaults set by gentoo?

The cflags currently in portage/make.conf are to specify the architecture of the machine.

ormorph commented 2 years ago

These flags were previously used when using genpi64 profiles link. These flags are now overridden by the CFLAGS option in /etc/portage/make.conf. It's just that this optimization accelerated some programs quite well. For example libsdl2.

OK. Thank you for pointing that out.

I would merge a pull request that fixes this problem.
