Description

[AArch32] Armv8.6a Matrix Mul Assembly Parsing Support

This patch upstreams support for the Armv8.6-a Matrix Multiplication
Extension. A summary of the features can be found here:

https://community.arm.com/developer/ip-products/processors/b/processors-ip-blog/posts/arm-architecture-developments-armv8-6-a

This patch includes:

  • Assembly support for AArch32 and Assembly Parsing

D77872 has already added the MC representations of the instructions so that
they can be used in code gen; this patch fills in the details needed to
make assembly parsing work, and adds tests for asm and disasm

This is part of a patch series, starting with BFloat16 support and
the other components in the armv8.6a extension (in previous patches
linked in phabricator)

Based on work by:

  • Luke Geeson
  • Oliver Stannard
  • Luke Cheeseman
