Created attachment 803809 [details] compressed build log with gcc-11.3.0 reproduced with native gcc-11.3.0
I've opened an issue with upstream a few weeks ago, and it seems there is nothing the devs can do to help with the issue. Therefore, can please someone from the toolchain team have a look at this? easy reproducer: emerge -av =dev-cpp/highway-9999 [ebuild U *] dev-cpp/highway-9999::gentoo [0.17.0::gentoo] to /usr/armv7a-unknown-linux-gnueabihf/ USE="-test" 0 KiB

Try adding -mfpu=neon to *FLAGS.
There is a HWY_CMAKE_ARM7 cmake flag, which enables NEON (default off). Maybe enable it with arm neon USE expand.
Created attachment 803824 [details, diff] patch for the ebuilds alas, you're right with passing neon flags. the attached patch fixes the issue, I think it will force neon to all ARCH=arm and ignore all other ARCH. please commit if you feel its correct, but really no need to post my private email in the public commit msg. Thank you.
