0767e43d - [CostModel][X86] Adjust bitreverse/ctpop/ctlz/cttz AVX2+ costs based on llvm-mca reports

[CostModel][X86] Adjust bitreverse/ctpop/ctlz/cttz AVX2+ costs based on llvm-mca reportsBased off the worse case numbers generated by D103695, the AVX2/512 bit reversing/counting costs were higher than necessary (based off instruction counts instead of actual throughput).

f0b0bab3 - [X86] Use GF2P8AFFINEQB to implement vector bitreverse.

Wed, 18 Nov 2020 05:34:34 +0000

[X86] Use GF2P8AFFINEQB to implement vector bitreverse.We can use GF2P8AFFINEQB to reverse bits in a byte. Shuffles are needed to reverse the bytes in elements larger than i8. LegalizeVectorOps takes care of inserting the shuffle for the larger element size.We already have Custom lowering for v16i8 with SSSE3, v32i8 with AVX, and v64i8 with AVX512BW.I think we might be able to use this for scalars too by moving into a vector and back. But I'll save that for a follow up as its a little more involved.Reviewed By: RKSimon, pengfeiDifferential Revision: https://reviews.llvm.org/D91515 List of files: /llvm-project-15.0.7/llvm/test/Analysis/CostModel/X86/bitreverse.ll

7034d401 - [X86] Use mattr instead of mcpu in some of the cost model tests.

Mon, 18 Dec 2017 07:21:58 +0000

[X86] Use mattr instead of mcpu in some of the cost model tests.Based on the names of the check lines, features seems more appropriate that cpu.Spotted while prototyping my patch to make 512-bit vectors illegal on SKX sometimes.llvm-svn: 320959 List of files: /llvm-project-15.0.7/llvm/test/Analysis/CostModel/X86/bitreverse.ll
