Commit 7b83837af6f472e9c0ed0b96b78717d4a3c4dbfe by sam.mccall [clangd] Bind outgoing calls through LSPBinder too. NFC The redundancy around work-done-progress is annoying but ok for now. There's a weirdness with context lifetimes around outgoing method calls, which I've preserved to keep this NFC. We should probably fix it though.

Commit ca9815fc247cc738f3ca7c8d5f482049371ca6e1 by Alexander.Richardson [sanitizers] Define SANITIZER_INTERCEPTOR_HOOKS on FreeBSD This fixes the weak_hooks.cpp test on FreeBSD. Since this feature appears to be supported on almost all platforms, it might also make sense to turn it into an opt-out list instead of being opt-in.

Commit 1e2d50936a3bff2c8065a99d06f37b51185fbd81 by thomasp Add lit config for dir with standalone tests Some test systems do not use lit for test discovery but only for its substitution and test selection because they use another way of managing test collections, e.g. CTest. This forces those tests to be invoked with lit --no-indirectly-run-check. When a mix of lit version is in use, it requires to detect the availability of that option. This commit provides a new config option standalone_tests to signal a directory made of tests meant to run as standalone. When this option is set, lit skips test discovery and the indirectly run check. It also adds the missing documentation for --no-indirectly-run-check.

Commit 08131c7439336e84b9df3e37b3aaeb76b8f60702 by Piotr Sobczak [AMDGPU] Fix a miscompile with S_ADD/S_SUB The helper function isBoolSGPR is too aggressive when determining when a v_cndmask can be skipped on a boolean value because the function does not check the operands of and/or/xor. This can be problematic for the Add/Sub combines that can leave bits set even for inactive lanes leading to wrong results. Fix this by inspecting the operands of and/or/xor recursively.

With this change, a test suite can improve performance (for high-end systems) by listing just a few of the slowest tests up front.

Commit 05c64ea6722bc973ebf61653342518d065316feb by llvm-dev [DAG] Fold shuffle(bop(shuffle(x,y),shuffle(z,w)),bop(shuffle(a,b),shuffle(c,d))) (REAPPLIED) Fold shuffle(bop(shuffle(x,y),shuffle(z,w)),bop(shuffle(a,b),shuffle(c,d))) -> bop(shuffle(x,y),shuffle(z,w)),bop(shuffle(a,b),shuffle(c,d)) Attempt to fold from a shuffle of a pair of binops to a binop of shuffles, as long as one/both of the binop sources are also shuffles that can be merged with the outer shuffle. This should guarantee that we remove one binop without introducing any additional shuffles. Technically there's potential for a merged shuffle's lowering to be poorer than the original shuffle, but it could also be better, and I'm not seeing any regressions as long as we keep the 'don't merge splats' rule already present in MergeInnerShuffle. This expands and generalizes an existing X86 combine and attempts to merge either of each binop's sources (with an on-the-fly commutation of the shuffle mask) - we couldn't do that in the x86 version as it had to stay in a form that DAGCombine's MergeInnerShuffle would still recognise. Fixes issue raised by @saugustine in rG5aa8f4c0843a where we were failing to replace null shuffle operands from MergeInnerShuffle to UNDEFs. Differential Revision: https://reviews.llvm.org/D96345
