GCC incorrect compilation when targeting native goldmont-plus

Support AUR
1

When trying to run dsda-doom, or its fork nyan-doom or gzdoom/uzdooom-git compiled with AUR’s pkgbuild, with the flag -march=goldmont-plus, both results in segmentation fault. Some ports can get to the menu but whenever it reachs to a ingame scenario, it results in a crash.

log from a failed nyan-doom run:

Please report the following information: Segmentation fault (0x0000)

Atleast some of those ALSA errors appear trivial as running these applications compiled with -march=x86-64-v2 results in a normal run.

So far these are the only programs these errors are encountered.

This system’s cpu is a Celeron N4020c

Comment on AUR page does not mention use of -march=goldmont-plus or -march=x86-64-v2

AUR (en) - nyan-doom

Compile but when running DOOM or any mod/map it returns:

Is it even worth it?
To investige this?

Would not have -march=native have sufficed?

… I have spent way too much time on Gentoo and the like.

None of this optimization will make a noticable difference to you.

None of it. :wink:
