yes, I plan submit it as CodeGen part.
But I can add it into this patch if it is required.

the [[

spec ]] says:
> The Zcmt extension depends on the Zca and Zicsr extensions.

I think maybe `zcmt` needs to be aligned using `c.nop`?  That might be one of 
the reasons why `zcmt` required `zca`.

Comment at: clang/test/Driver/riscv-arch.c:376
 
-// RUN: %clang --target=riscv32-unknown-elf -march=rv32izca -### %s \
+// RUN: %clang --target=riscv32-unknown-elf -march=rv32izfa -### %s \
 // RUN: -fsyntax-only 2>&1 | FileCheck -check-prefix=RV32-EXPERIMENTAL-NOFLAG 
%s

does it should be `zca`?

because zcmt have add a new elf section `.riscv.jvt`, that extent the size of

[PATCH] D118011: [RISCV] Adjust predicates and update intrinsic for clmul and clmulh in Zbkc extension

2022-01-24 Thread Xinlong Wu via Phabricator via cfe-commits

VincentWu added a comment.

Hi, Jimerlife

it is a great work to implement the intrinsic of `zbkb`.
however, I don't know whether you have noticed that there is already to patch 
https://reviews.llvm.org/D112774 and https://reviews.llvm.org/D102310.
these two patches have included almost all the work you did in your patch.

I think we should better avoid overlap as much as possible.

therefore, could you please comment on the difference between these two patches 
as you see it?
let's focus on only one version.

You are also welcome to join the bi-weekly LLVM RISC-V meetings to discuss with 
us if you want. You can subscribe to the calendar via this link
