[PATCH] D150929: [RISCV][BF16] Enable __bf16 for riscv targets

[Alex Bradbury via Phabricator via llvm-commits]

asb added a comment.

I feel (IMHO) this is jumping to the endpoint a bit - the usual route for something like this is:

- MC layer support
- LLVM codegen support (and tests!)
- Any needed Clang support

I was hoping to push out some patches related to zfbfmin tests+codegen today but might time-out (if so, I'll return to it tomorrow).

I think the tentative conclusion of https://discourse.llvm.org/t/rfc-c-23-p1467r9-extended-floating-point-types-and-standard-names/70033 is to make __bf16_t an arithmetic type on all targets - I'd recommend keeping an eye on https://reviews.llvm.org/D150913 (and ideally helping to review it), as that's bound to interact with this patch.
