Attachment 197016: v0 https://bugs.freebsd.org/bugzilla/attachment.cgi?id=197016&action=edit --- Comment #1 from Jan Beich <jbe...@freebsd.org> --- Created attachment 197016 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=197016&action=edit v0 Clang hides vcvt_f16_f32() and vcvt_f32_f16() behind (__ARM_FP & 2) where 2 refers to -mfpu=fp-armv8. However, GCC would only build this code if -march=armv8.2-a+fp16 is passed as well. $ clang60 -dM -E -</dev/null | fgrep __ARM_FP #define __ARM_FP 0xc #define __ARM_FP16_ARGS 1 #define __ARM_FP16_FORMAT_IEEE 1 $ clang60 -mfpu=fp-armv8 -dM -E -</dev/null | fgrep __ARM_FP #define __ARM_FP 0xe #define __ARM_FP16_ARGS 1 #define __ARM_FP16_FORMAT_IEEE 1 #define __ARM_FPV5__ 1 $ gcc7 -dM -E -</dev/null | fgrep __ARM_FP #define __ARM_FP 12 $ gcc7 -mfpu=fp-armv8 -dM -E -</dev/null | fgrep __ARM_FP #define __ARM_FP 14 $ gcc7 -march=armv8.2-a+fp16 -mfpu=fp-armv8 -dM -E -</dev/null | fgrep __ARM_FP #define __ARM_FP 14 #define __ARM_FP16_FORMAT_IEEE 1 #define __ARM_FP16_ARGS 1 build log: https://ptpb.pw/MxS9
