Bug 252698 – sys-devel/gcc-3.3.6-r1 should replace more cpu flags

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Le retraité 2008-12-27 14:56:53 UTC]

In the current portage gcc-3.3.6-r1 ebuild, there is 'replace-cpu-flags k8 athlon64 opteron i686'. But for amd64 and x86, more cpu flags should be replaced (such as pentium-m in my case)

Worked greate for my old pentium-m pc, thanks ! However, last week I bought a core2, can you add core2 to replace-cpu-flags in eclass/toolchain.eclass ?

mmmh... according to this:

I think toolchain.eclass should be patched this way:

You may also add this:
	replace-cpu-flags G3 750
	replace-cpu-flags G4 7400
	replace-cpu-flags G5 7400

from http://sources.gentoo.org/viewcvs.py/gentoo-x86/sys-libs/libstdc%2B%2B-v3/libstdc%2B%2B-v3-3.3.6.ebuild?rev=1.24

These all seem to be in the eclass already, but this wasn't closed.
