    • AArch64: Update Armv8.4-a's FP16 FML intrinsics · 9d04c986 
      This patch updates the Armv8.4-a FP16 FML intrinsics's suffixes from u32 to f16
to be more consistent with the naming convention for intrinsics.

The specifications for these intrinsics have not been published yet so we do
not need to maintain the old names.

The patch was created with the following script:

grep -lIE "(vfml[as].+)_u32" -r gcc/ | grep -iEv ".+Changelog.*" \
  | xargs sed -i -E -e "s/(vfml[as].+)_u32/\1_f16/g"
