Commit d970a285b8567b93aea39e7e4d10965fe8b7340c by johannes [OpenMP][Fix] Make the arch selector for x86_64 work The triple uses a bar "x86-64" instead of an underscore. Since we have troubles accepting x86-64 as an identifier, we stick with x86_64 in the frontend and translate it explicitly.

Commit 36c4dc9b42fe2e6af4ab488b7c4013d5082b67f6 by johannes [OpenMP][FIX] Ensure the isa trait is evaluated last Since isa can cause diagnostics we want it to be evaluated last to avoid the "unknown isa" warning if the rest of the selector wouldn't match anyway. That allows us to guard isa with arch properly. Reviewed By: jhuber6 Differential Revision: https://reviews.llvm.org/D93785

Commit 275f30df8ad6de75e1f29e4b33eaeb67686caf0d by George Burgess IV [clang] Change builtin object size when subobject is invalid Motivating example: ``` struct { int v[10]; } t[10]; __builtin_object_size( &t[0].v[11], // access past end of subobject 1 // request remaining bytes of closest surrounding // subobject ); ``` In GCC, this returns 0. https://godbolt.org/z/7TeGs7 In current clang, however, this returns 356, the number of bytes remaining in the whole variable, as if the `type` was 0 instead of 1. https://godbolt.org/z/6Kffox This patch checks for the specific case where we're requesting a subobject's size (type 1) but the subobject is invalid.

Commit 70b841ac317765c5c504334f7a22ac085f14ac2d by eschweitz [mlir] Adds argument attributes for using LLVM's sret and byval attributes to the conversion of LLVM IR dialect. These attributes are used in FIR to support the lowering of Fortran using target-specific calling conventions. Add roundtrip tests. Add changes per review comments/concerns.
