[clang] [AArch64] add some more tests for FMV (PR #91490)

2024-05-08 Thread Tomas Matheson via cfe-commits 

tmatheson-arm wrote:

The autogenerated checks for `clang/test/CodeGen/aarch64-fmv-dependencies.c` 
did not actually pass, due to changes in function ordering, so I have manually 
written the check lines, which makes the intent clearer anyway.

Some things look odd to me:
- The "aes", "dgh", "fp", "ls64", "ls64_v", "memtag", "rpres", "sha1", "simd", 
"ssbs" functions all have the same set of `target_features`: 
`"+fp-armv8,+neon,+outline-atomics,+v8a"`
- `bf16` and `ebf16` seem to be equivalent, and `+ebf16` doesn't get added to 
the `target-features`
- `memtag2` and `memtag3` both have the same `target-features` (which has only 
`+mte`)
- `+fp-armv8,+neon` are present in all cases. I'm guessing this is due to the 
base architecture enabling them. However, disabling them with `-march=+nofp` 
adds `-fp-armv8,-neon` to all `target-features`, even where the 
`target_version` should re-enable it.

Are any of these cause for concern?
