Nikita Popov 6d326a1c6b [PatternMatch] Make m_c_ICmp swap the predicate (PR42801) ... This addresses https://bugs.llvm.org/show_bug.cgi?id=42801. The m_c_ICmp() matcher is changed to provide the swapped predicate if the operands are swapped. Existing uses of m_c_ICmp() fall in one of two categories: Working on equality predicates only, where swapping is irrelevant. Or performing a manual swap, in which case this patch removes it. The only exception is the foldICmpWithLowBitMaskedVal() fold, which does not swap the predicate, and instead reasons about whether a swap occurred or not for each predicate. Getting the swapped predicate allows us to merge the logic for pairs of predicates, instead of duplicating it. Differential Revision: https://reviews.llvm.org/D72976		2020-01-22 22:56:26 +01:00
