DESCRIPTION: ------------ psemu-peopsspu can fail from building because the Makefile adds the deprecated option "-mpentium" to CFLAGS REASON: ------- The option "-mpentium" is deprecated and can break the build on other processors than pentium. The bug is reproducable by setting CFLAGS="-march=athlon-tbird -fprefetch-loop-arrays". SOLUTION: --------- Remove the "-mpentium" from the Makefile. This breaks nothing and owners of pentiums have their "-march=pentium" in /etc/make.conf. ERROR-LOG: ---------- gcc -march=athlon-tbird -fprefetch-loop-arrays -fPIC -c -Wall -mpentium -O3 -ffast-math -fomit-frame-pointer -DUSEALSA dma.c `-mpentium' is deprecated.

Created attachment 16123 [details, diff] patch to fix compiling on other processors than pentium apply patch with: cd /usr/portage/app-emulation/psemu-peopsspu patch < psemu-peopsspu-1.0.7-r1.ebuild.diff
This is your error: dma.c:64: internal error: Floating point exception This has nothing to do with the -mpentium being in the source, at least at first glance. Have you tried removing the -mpentium from the Makefile and compiling it by hand to see if it fails? If removing the flag solves the problem, then I'll modify the ebuild to fix the Makefile.
Yes, I tried it. Removing the "-mpentium" from the Makefile fixes the build on my "-march=athlon-tbird". Seems that gcc gets confused how to optimize the code if there is "-march=athlon-tbird -mpentium" together. The modified sed-expression in my .diff removes the -mpentium from the Makefile. This will have no bad sideeffects to anybody, because every normal gentoo-user with a pentium processor has his "-mpentium" or better "-march=pentium" in his CFLAGS. Please remove the flag from the Makefile. I think there are many people without pentium processor out there ;-)
Fixed in CVS
