rG322d0afd875d: [llvm][mlir] Promote the experimental reduction intrinsics to be first class…
Summary

This change renames the intrinsics to not have "experimental" in the name.

The autoupgrader will handle legacy intrinsics.

@aartbik @rriddle @nicolasvasilache MLIR also needed updating to use these new intrinsics, please take a look.

Underlines for titles need adjustment.

Please also add fast variants for these two tests, to make sure the operand is not replaced with 0/1 if the v2 intrinsics were used.

Can we not just drop support for the v1 experimental fmul/fadd now? As @nikic said there is a danger of this matching against the v2 variants upgraded above as well.

Yeah I think we can probably drop support. I'll remove this special handling so we're only effectively renaming the existing set.

Seeing this, I'm wondering whether we shouldn't change the type signature for fadd/fmul to omit the separate scalar type. It should be sufficient to have vector.reduce.fadd.v4f32 rather than vector.reduce.f32.v4f32. The scalar argument has to match the vector type, just the like return type already has to match.

Given that we're using the term "sequential" in D88791 (and I think that's a good change), should we do the same here for consistency? That could be considered an improvement independently of removing "experimental".

Sounds like a good idea. I'll do that as a separate change after D88791 lands.

aemerson updated this revision to Diff 296603.Oct 6 2020, 10:27 PM

Remove the scalar input overload for fadd/fmul. Now the signature is simple llvm.reduce.fadd.v4f32 rather than llvm.reduce.fadd.f32.v4f32

Also fix some langref formatting, and fold in the change to use "sequential" instead of "ordered" while I'm there.

It's redundant/unnecessary to mention 'fast' here (and in the fmul overview) because 'fast' is just an alias for all FMF including 'reassoc'.

Yep, I've just pushed c1247f0e74bff00ab9a896a8132318916f3e84a7 to hopefully fix that.

Seeing this, I'm wondering whether we shouldn't change the type signature for fadd/fmul to omit the separate scalar type. It should be sufficient to have vector.reduce.fadd.v4f32 rather than vector.reduce.f32.v4f32. The scalar argument has to match the vector type, just the like return type already has to match.

Can we not just drop support for the v1 experimental fmul/fadd now? As @nikic said there is a danger of this matching against the v2 variants upgraded above as well.

Yeah I think we can probably drop support. I'll remove this special handling so we're only effectively renaming the existing set.
