Hi, I'm on stable keywords and have the experimental useflag enabled. This used to enable among other things, the ability to select CONFIG_MNATIVE for the processor type. However, very recently, this changed and when emerging the kernel I gets: >>> Unpacking genpatches-4.19-23.experimental.tar.xz to /var/tmp/portage/sys-ker * Excluding Patch #5010_enable-additional-cpu-optimizations-for-gcc.patch ... * Excluding Patch #5011_enable-cpu-optimizations-for-gcc8.patch ... * Excluding Patch #5010_enable-additional-cpu-optimizations-for-gcc.patch ... * Excluding Patch #5011_enable-cpu-optimizations-for-gcc8.patch ... * Excluding Patch #5010_enable-additional-cpu-optimizations-for-gcc.patch ... * Excluding Patch #5011_enable-cpu-optimizations-for-gcc8.patch ... * Applying 1000_linux_4.19.1.patch (-p1) ... * Applying 1001_linux-4.19.2.patch (-p1) ... * Applying 1002_linux-4.19.3.patch (-p1) ... Like I say, I'm on stable so have gcc-7.3.0-r3, so the 5010 patches should be applied?

Can you run and attach the full output of: ECLASS_DEBUG_OUTPUT=on USE=experimental ebuild gentoo-sources-4.19.24.ebuild clean unpack and ECLASS_DEBUG_OUTPUT=on USE=-experimental ebuild gentoo-sources-4.19.24.ebuild clean unpack

Looks like 5010 is applied with use=experimental <snip> * Applying 4567_distro-Gentoo-Kconfig.patch (-p1) ... [ ok ] * Applying 5010_enable-additional-cpu-optimizations-for-gcc-4.9.patch (-p1) ...

Hi Mike, the possible bug was with .23 (just attached as 'USE=experimental on 4.19.23') rather than .24. Stable kernels have worked previously (4.14.83) with MNATIVE being available from menuconfig. Is .23 not supposed to have that?
Yeah, I probably broke that. I'll take a look.
Yeah, my bad. I just committed a fix to kernel-2.eclass a few seconds ago. It will take a little time to get to the mirrors but it was a one line change. You can get the new file right away directly from here: https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/kernel-2.eclass?id=d71fe9c18bd7fe412185f3ca79379c631bde79b2 Otherwise, wait a bit, then sync and give it a try and report back if you don't mind.
Just got hit by this myself for gentoo-sources-4.20.11 Even with having commit d71fe9c18bd7fe412185f3ca79379c631bde79b2 and sys-devel/gcc-8.2.0-r6 the patch is not being applied. Expected behavior or still broken?
That works for me Mike, I gave it a go with the amd64 stable 4.14.83, 4.14.101, 4.19.23, and latest - 4.20.11, 5010 is being applied to all of these when experimental is on, and not when experimental is off. Thank you, that was a super-responsive fix.

Hey there, that sounds like https://bugs.gentoo.org/678556 rather than this bug.
This one is fixed so I'm going to close it. For everyone that has gcc v8 and wants to follow along with the progress for the cpu optimization patch for >= 4.20 please go to bug #678556 .
