[PATCH 0/4] aarch64: Add mf8 data movement intrinsics

[Richard Sandiford]

This series adds mf8 variants of what I'll loosely call the existing
"data movement" intrinsics, including the recent FEAT_LUT ones.
I think this completes the FP8 intrinsic definitions.

Sorry that the series is so late.  We did make a real effort to get
it done by the end of stage 1, but there were some unexpected hitches.
The current half-complete state of trunk means that we either need
to apply this patch or disable the existing __ARM_FEATURE_FP8 definition.

Tested on aarch64-linux-gnu and aarch64_be-elf (including ILP32).
I also tested advsimd-intrinsics.exp on arm-eabi to make sure that
the mf8 stuff was properly protected.

I'll commit this when the prerequisite x86 changes in:

  https://gcc.gnu.org/pipermail/gcc-patches/2024-December/671924.html

are approved, unless there are no comments before then.

The main patch was co-authored by Saurabh.

Thanks,
Richard
