src_compile fails with the following error. Note that -mcpu=power9 is already in CFLAGS (and CXXFLAGS etc). I think -mcpu=power9 implies -mvsx, but just in case I also tried building again after adding -mvsx to *FLAGS and it still gives the same error.

I see -mcpu=power9 being passed correctly, so I'm confused as to whether -mvsx got stripped somehow or the compiler is misbehaving.
Created attachment 900101 [details] Log of failed build with `-mvsx` Here is the result when building with `-mvsx` in *FLAGS - it is almost exactly the same as without `-mvsx`.
Well, FWICS it passes both `-mvsx` and `-mcpu=power9`, so perhaps it is a GCC bug?
Created attachment 901184 [details] Log of failed build of numpy 2.1.0 I tried building numpy 2.1.0 and got the same error.
I tried installing upstream numpy from a git checkout of the v2.0.0 tag with ./venv-numpy/bin/pip install ./numpy/ That seems to have worked (with no FLAGS in the environment)
Hit this bug as well It appears that "-mcpu=power8" and "-O3" are being added to the build flags (after, and in addition to make.conf:CFLAGS="-mcpu=native" or -mcpu=power9). I think that would foul up gcc.
Created attachment 905623 [details] Log of build without -mcpu I tried building without any `-mcpu` or `-mtune` in CFLAGS. This time the src_compile succeeded (the logs show -mcpu=power8 being added by the numpy build script, but no `-DNPY_HAVE_VSX3` etc), but it failed src_test with an error in float128, probably related to the switch to ieee long double while numpy is still expecting the old behaviour?
numpy 2.0.2-r1 still has the same problem in src_compile with -mcpu=power9, but if I compile it without any -mcpu in CFLAGS then it now also passes src_test (unlike 2.0.0).
