13_gcc31-compile-optimizations has a bad gcc option for pentium pros. It adds -mmmx, and ppro's dont have mmx. Also, in the config.in portion, there is a missing define_bool CONFIG_X86_PPRO_FENCE y in the 'if [ "$CONFIG_M68631" = "y" ]; then' section. I'll attach a new patch, that splits into two configure options, one for ppro's, and another for pentium2/celeron, and fixes the missing PPRO_FENCE option. Reproducible: Always Steps to Reproduce:
Created attachment 7808 [details, diff] proposed new 13_gcc31-compile-optimizations patch
The new patch has been in gentoo-sources for a while, so I was thinking that this could be closed, however it looks like gaming-sources-2.4.20-r2 is still using the old patch. I haven't checked any of the other kernel sources.
gaming sources is updated. closing.
