Roman Lebedev 034e32765e [SROA] rewritePartition()/findCommonType(): if uses have conflicting type, try getTypePartition() before falling back to largest integral use type (PR47592) ... And another step towards transformss not introducing inttoptr and/or ptrtoint casts that weren't there already. In this case, when load/store uses have conflicting types, instead of falling back to the iN, we can try to use allocated sub-type. As disscussed, this isn't the best idea overall (we shouldn't rely on allocated type), but it works fine as a temporary measure. I've measured, and @ `-O3` as of vanilla llvm test-suite + RawSpeed, this results in +0.05% more bitcasts, -5.51% less inttoptr and -1.05% less ptrtoint (at the end of middle-end opt pipeline) See https://bugs.llvm.org/show_bug.cgi?id=47592 Reviewed By: efriedma Differential Revision: https://reviews.llvm.org/D88788		2020-10-07 09:20:19 +03:00
