Commit 91aeacc06b0e71815f7808fb27daf3664325c282 by richard-llvm Move most CXXRecordDecl::DefinitionData bit-fields out into a separate file. Reduces duplication and thereby reduces the risk that someone will forget to update one of these places, as I did when adding DefaultedDestructorIsConstexpr (though I've been unable to produce a testcase for which that matters so far). llvm-svn: 374484

Commit 4dc27c69b6d13d497b2bd9f430d91ce3dab8847b by craig.topper [X86] Update trunc_packus_v32i32_v32i8 test in min-legal-vector-width.ll to use a load for the large type and add the min-legal-vector-width attribute. The attribute is needed to avoid zmm registers. Using memory avoids argument splitting for large vectors. llvm-svn: 374486

Commit b560fd6c52eb5ce52315fff97f65952b53298728 by craig.topper [X86] Improve the AVX512 bailout in combineTruncateWithSat to allow pack instructions in more situations. If we don't have VLX we won't end up selecting a saturating truncate for 256-bit or smaller vectors so we should just use the pack lowering. llvm-svn: 374487
