…m#164983) Avoids adding alternative libcall impls for the same libcall. I'm not sure if the default names exist or not, or are just not preferred. compiler-rt appears to define aliases for all of these, so I'm not sure why we bother distinguishing these in the first place.
Prefer getSubtarget<AArch64>(). Also avoids one unnecessary null check.
82289aa refactored this function to not need this parameter.
…lvm#164957) Previous implementation was cmp, select and @llvm.smax sequence in LLVM IR. __CLC_GEN_U/__CLC_GEN_S is upstreamed from intel/llvm repo.
The map returned by collectStridedAccess is used to replace strides with their versioned values. This does not work for Undef/Poison, which don't have use-lists. Don't try to version them, as versioning won't be useful in practice. Fixes llvm#162922.
This patch achieves the "Rule of Zero" in DGNode by removing the copy/move constructors and copy/move assignment operators. Note that the code being deleted does a couple of unusual things that are most likely oversight: - The copy constructor with "explicit" is highly unusual. This means that we allow "DGNode<N, E> A(B);" but disallow "DGNode<N, E> A = B;". - The move assignment operator with const r-value reference is also unusual, especially given that the move constructor is correctly implemented.
…lvm#165191) This patch folds "std" into the std::hash specialization so that the template mentions std::hash. std::hash is much easier to recognize than std and hash separated by a couple of lines.
This commit adds a new RadixTree to `SpecialCaseList` for handling substring matches. Previously, `SpecialCaseList` only supported prefix and suffix matching. With this change, patterns that have neither prefixes nor suffixes can now be efficiently filtered. According to SpecialCaseListBM: Lookup benchmarks (significant improvements): ``` OVERALL_GEOMEAN -0.7809 ``` Lookup `*test*` like benchmarks (huge improvements): ``` OVERALL_GEOMEAN -0.9947 ``` https://gist.github.com/vitalybuka/ee7f681b448eb18974386ab35e2d4d27
