The build failure happens on gcc-15 since r15-902-geff00046409a72 (bisected): commit eff00046409a7289bfdc1861e68b532895f91c0e Author: Jason Merrill <jason@redhat.com> Date: Wed Feb 14 17:18:17 2024 -0500 c++: pragma target and static init [PR109753] Looks relevant. The build fails as: hwy/base.h:1006:40: error: inlining failed in call to 'always_inline' 'constexpr To hwy::BitCastScalar(const From&) [with To = short unsigned int; From = float16_t; EnableIf<((bool)(!
