I have a feeling sys-devel/gcc forces -O2 as I recently failed trying to change it?
Thks 4 ur attention, interest & support.

| Per eclass/toolchain.eclass, if you do not USE=custom-cflags, then yes, this is forced, because too many people had problems with overly aggressive CFLAGS. |

| Actually, it has a special rule for -O3 where it'll use the custom target "bootstrap-O3" and then filter it (this lets upstream handle using -O3 similarly to lto with bootstrap-lto). It should use -O3 for most of the build (regardless of custom-cflags), and seems to use it fine for me at a glance. |

Well,
didn't show custom-flags for some reason.
Thus confused pov.
Target is to lower the value here.

I actually meant forced by upstream, not gentoo portage tree.
custom-cflags in make.conf for years now.

echoed build log returns -02 whereas -01 from above is expected.
/etc/portage/package.env has been cleaned up to not interfere.
-02 seems hardcoded to me.
