rGc89d9d8a48c0: [TTI] Consider select form of and/or i1 as having arithmetic cost
Summary

This is a patch that updates the cost of select i1 a, b, false to be equivalent to that of and i1 a, b
as well as the cost of select i1 a, true, b equivalent to or i1 a, b.

Until now, these selects were folded into and/or i1 by InstCombine, but the transformation is poison-unsafe.
This is a step towards removing the unsafe transformation. D93065 has relevant transformations linked.
These selects should be translated into the assemblies as and/or i1 do in the same manner. The cost should be equivalent.

This patch has tests missing, and I'd like to add these. Where should I go to do this?

I can't tell from the tests (so we should probably add at least 1 to confirm) - do we expect the same behavior for vector types?

llvm/include/llvm/Analysis/TargetTransformInfoImpl.h
997

It would be nice to have a code comment here to show the expected patterns:

// select x, y, false --> x & y
// select x, true, y --> x | y
aqjune added a comment.Mar 1 2021, 7:41 AM

Yes, vectors are expected to have the same cost. I'll update tests for them.

Thanks - IIUC, we're also going to need to some codegen changes to avoid regressions. For example (the icmps are to avoid diffs due to lack of signext/zeroext specifiers on parameters with vector type):

define <4 x i1> @b(<4 x i32> %x, <4 x i32> %y) {
  %c1 = icmp eq <4 x i32> %x, <i32 42, i32 42, i32 42, i32 42>

Thank you for the info..!
I'll check whether regression happens with different targets as well and make patches if any.

select form of and/or operations are eagerly folded by InstCombine currently, so they'll look good hopefully.

Would adding 'select -> and/or i1' transformation into the end of CodeGenPrepare::runOnFunction work?
I see that there are quite many targets that generate different assemblies for select vs. and/or i1.

No, I think we should adjust some code in DAGCombiner for this. I was already looking at it, so I can continue if you want to keep working on the IR side.

LGTM.
