Technical tradeoffs

  • • Adding support for new instruction sets requires extensive modifications to opcode tables and disassembler logic, increasing maintenance overhead.
  • • The use of EVEX encoding for these instructions necessitates careful handling of prefix bytes and register specifiers to ensure correct assembly and disassembly.

[PATCH v4 7/7] x86: add ACE V1 tile outer product instructions

This patch enhances binutils by adding assembler and disassembler support for several x86 ACE V1 tile outer product instructions: TOP2BF16PS, TOP4B*, and TOP4MX*. The changes include updates to the NEWS file, test suites, and various opcode and disassembler-related header files. This brings comprehensive support for these advanced matrix operations to the toolchain.
