Commit 08ed216000b6503a4a4be52f18394d008d5fb8f4 by i [IR] Refactor GlobalIFunc to inherit from GlobalObject, Remove GlobalIndirectSymbol As discussed in: * https://reviews.llvm.org/D94166 * https://lists.llvm.org/pipermail/llvm-dev/2020-September/145031.html The GlobalIndirectSymbol class lost most of its meaning in https://reviews.llvm.org/D109792, which disambiguated getBaseObject (now getAliaseeObject) between GlobalIFunc and everything else. In addition, as long as GlobalIFunc is not a GlobalObject and getAliaseeObject returns GlobalObjects, a GlobalAlias whose aliasee is a GlobalIFunc cannot currently be modeled properly. Creating aliases for GlobalIFuncs does happen in the wild (e.g. glibc). In addition, calling getAliaseeObject on a GlobalIFunc will currently return nullptr, which is undesirable because it should return the object itself for non-aliases. This patch refactors the GlobalIFunc class to inherit directly from GlobalObject, and removes GlobalIndirectSymbol (while inlining the relevant parts into GlobalAlias and GlobalIFunc). This allows for calling getAliaseeObject() on a GlobalIFunc to return the GlobalIFunc itself, making getAliaseeObject() more consistent and enabling alias-to-ifunc to be properly modeled in the IR. I exercised some judgement in the API clients of GlobalIndirectSymbol: some were 'monomorphized' for GlobalAlias and GlobalIFunc, and some remained shared (with the type adapted to become GlobalValue).

Commit 80ab06c599a0f5a90951c36a57b2a9b492b19d61 by spatel [InstCombine] fold fake vector insert to bit-logic bitcast (inselt (bitcast X), Y, 0) --> or (and X, MaskC), (zext Y) https://alive2.llvm.org/ce/z/Ux-662 Similar to D111082 / db231ebdb07f : We want to avoid relatively opaque vector ops on types that are likely supported by the backend as scalar integers. The bitwise logic ops are more likely to allow further combining. We probably want to generalize this to allow a shift too, but that would oppose instcombine's general rule of not creating extra instructions, so that's left as a potential follow-up. Alternatively, we could do that transform in VectorCombine with the help of the TTI cost model. This is part of solving: https://llvm.org/PR52057

Commit bd5494d127a39f619b7d0e5e967f190e0e61d6e7 by ajcbik [mlir][sparse] make index type explicit in public API of support library The current implementation used explicit index->int64_t casts for some, but not all instances of passing values of type "index" in and from the sparse support library. This revision makes the situation more consistent by using new "index_t" type at all such places (which allows for less trivial casting in the generated MLIR code). Note that the current revision still assumes that "index" is 64-bit wide. If we want to support targets with alternative "index" bit widths, we need to build the support library different. But the current revision is a step forward by making this requirement explicit and more visible. Reviewed By: wrengr Differential Revision: https://reviews.llvm.org/D112122

Commit 8977bd58067d9dcd5e8cebd078c45ff629af9e1d by flo [IndVars] Invalidate SCEV when IR is changed in rewriteLoopExitValue. At the moment, rewriteLoopExitValue forgets the current phi node in the loop that collects phis to rewrite. A few lines after the value is forgotten, SCEV is used again to analyze incoming values and potentially expand SCEV expression. This means that another SCEV is created for PN, before the IR is actually updated in the next loop. This leads to accessing invalid cached expression in combination with D71539. PN should only be changed once the actual incoming exit value is set in the next loop. Moving invalidation there should ensure that PN is invalidated in all relevant cases.
