Subject: [PATCH 0/3] RISC-V: Add 'Zmmul' extension
Date: Sat, 9 Jul 2022 16:19:03 +0900 [thread overview]
Message-ID: <cover.1657351137.git.research_trasio@irq.a4lg.com> (raw)
Hello,
This patchset adds following extension to GNU Binutils:
- Zmmul (Multiply-only 'M' extension subset)
version 1.0 (recently ratified and version number determined)
This is based on the ISA Manual, draft-20220707-f518c25:
<https://github.com/riscv/riscv-isa-manual/releases/tag/draft-20220707-f518c25>
<https://github.com/riscv/riscv-isa-manual/commit/f518c259c008f926eba4aba67804f62531b6e94b>
This patchset also contains generic 'M' extension testcases.
[RFC: Concerns about implied extension]
Because 'Zmmul' extension is always implied by 'M', existence of 'Zmmul'
extension is reflected on RISC-V attributes section. It means, it also
changes ELF output on RV[32|64]IM with old specification.
If this behavior is undesirable, we could:
- Remove 'Zmmul' from implied extension list
- Check 'M' or 'Zmmul' on INSN_CLASS_ZMMUL
(instruction class may be renamed to INSN_CLASS_M_OR_ZMMUL)
Thanks,
Tsukasa
