Roman Lebedev 2927716277 [CVP] Deduce no-wrap on `mul` ... Summary: `ConstantRange::makeGuaranteedNoWrapRegion()` knows how to deal with `mul` since rL335646, there is exhaustive test coverage. This is already used by CVP's `processOverflowIntrinsic()`, and by SCEV's `StrengthenNoWrapFlags()` That being said, currently, this doesn't help much in the end: | statistic | old | new | delta | percentage | | correlated-value-propagation.NumMulNSW | 4 | 275 | 271 | 6775.00% | | correlated-value-propagation.NumMulNUW | 4 | 1323 | 1319 | 32975.00% | | correlated-value-propagation.NumMulNW | 8 | 1598 | 1590 | 19875.00% | | correlated-value-propagation.NumNSW | 5715 | 5986 | 271 | 4.74% | | correlated-value-propagation.NumNUW | 9193 | 10512 | 1319 | 14.35% | | correlated-value-propagation.NumNW | 14908 | 16498 | 1590 | 10.67% | | instcount.NumAddInst | 275871 | 275869 | -2 | 0.00% | | instcount.NumBrInst | 708234 | 708232 | -2 | 0.00% | | instcount.NumMulInst | 43812 | 43810 | -2 | 0.00% | | instcount.NumPHIInst | 316786 | 316784 | -2 | 0.00% | | instcount.NumTruncInst | 62165 | 62167 | 2 | 0.00% | | instcount.NumUDivInst | 2528 | 2526 | -2 | -0.08% | | instcount.TotalBlocks | 842995 | 842993 | -2 | 0.00% | | instcount.TotalInsts | 7376486 | 7376478 | -8 | 0.00% | (^ test-suite plain, tests still pass) Reviewers: nikic, reames, luqmana, sanjoy, timshen Reviewed By: reames Subscribers: hiraditya, javed.absar, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D69203 llvm-svn: 375396		2019-10-21 08:21:44 +00:00
