/usr/lib/gcc/aarch64-redhat-linux/10/include/arm_neon.h:34612:10: fatal
error: arm_bf16.h: No such file or directory

Comment 1 Jakub Jelinek 2020-01-21 12:52:30 UTC

Indeed, I have added the new i?86/x86_64 intrinsics but missed the arm/aarch64 ones, so we'll need
following.

Comment 2 Jakub Jelinek 2020-01-21 15:47:56 UTC

gcc-10.0.1-0.4.fc32 with this is building, but it will take at least 10 more hours to build on some slow architectures.

Comment 3 Remi Collet 2020-01-22 07:16:50 UTC

I confirm fix is ok: php 7.4.2 successfuly built with gcc 10.0.1-0.4.fc32

Thanks
