Commit 3ced23976aa8a86a17017c87821c873b4ca80bc2 by richard Refactor CompareReferenceRelationship and its callers in preparation for implementing the resolution of CWG2352. No functionality change, except that we now convert the referent of a reference binding to the underlying type of the reference in more cases; we used to happen to preserve the type sugar from the referent if the only type change was in the cv-qualifiers. This exposed a bug in how we generate code for trivial assignment operators: if the type sugar (particularly the may_alias attribute) got lost during reference binding, we'd use the "wrong" TBAA information for the load during the assignment.

Commit 298e183e813c884dd22816383405bae3ef9ef278 by Lang Hames [Orc][LLJIT] Use JITLink even if a custom JITTargetMachineBuilder is supplied. LLJITBuilder will now use JITLink on supported platforms even if a custom JITTargetMachineBuilder is supplied, provided that neither the code model, nor the relocation model, nor the ObjectLinkingLayerCreator is set.

Commit bce1cce6bf1286541c57690ab1129fbc02c60f93 by Artem Dergachev [analyzer] Teach MismatchedDealloc about initWithBytesNoCopy with deallocator. MallocChecker warns when memory is passed into -[NSData initWithBytesNoCopy] but isn't allocated by malloc(), because it will be deallocated by free(). However, initWithBytesNoCopy has an overload that takes an arbitrary block for deallocating the object. If such overload is used, it is no longer necessary to make sure that the memory is allocated by malloc().

Commit d79b11fefb8e92660893b8ccf9e21d23668a6c73 by francisvm [Remarks][Driver] Run dsymutil when remarks are enabled When clang is invoked with a source file without -c or -S, it creates a cc1 job, a linker job and if debug info is requested, a dsymutil job. In case of remarks, we should also create a dsymutil job to avoid losing the remarks that will be generated in a tempdir that gets removed. Differential Revision: https://reviews.llvm.org/D71675

Commit 6bf7c345f82a06107a541db80f1ae128844c307c by craig.topper [X86] Add test case to show incorrect formation of masked add from vselect+strict_fadd. The masked operation will suppress exceptions on masked out lanes. But that's not what vselect+strict_fadd means.

Commit f0df4218b67d0abe96867804b8932b9b88998f51 by craig.topper [X86] Add a simple hack to IsProfitableToFold to prevent vselect+strict fp operations from being folded into masked instructions. We really need to update the isel patterns to prevent this, but that requires some tablegen de-tangling. So this hack will work for correctness in the short term.

Commit 71eb8023d85e5201d32ea24194ec5bc07db23527 by tlively [WebAssembly] Add avgr_u intrinsics and require nuw in patterns Summary: The vector pattern `(a + b + 1) / 2` was previously selected to an avgr_u instruction regardless of nuw flags, but this is incorrect in the case where either addition may have an unsigned wrap. This CL changes the existing pattern to require both adds to have nuw flags and adds builtin functions and intrinsics for the avgr_u instructions because the corrected pattern is not representable in C.
