Roman Lebedev a4fc069a94 [NFC][InstCombine] '(Op1 & С) - Op1' -> '-(Op1 & ~C)' fold (PR44427) This decreases use count of Op1, potentially allows us to further hoist said 'neg' later on, and results in marginally better X86 codegen. Name: (Op1 & С) - Op1 -> -(Op1 & ~C) %o = and i64 %Op1, C1 %r = sub i64 %o, %Op1 => %n = and i64 %Op1, ~C1 %r = sub i64 0, %n https://rise4fun.com/Alive/rwgA https://godbolt.org/z/R_RMfM https://bugs.llvm.org/show_bug.cgi?id=44427		2020-01-03 21:25:48 +03:00

This directory contains test cases for the instcombine transformation.  The
dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
