It's in libSystem, so it doesn't bring in any new deps, and it's currently much faster than LLVM's current SHA256 implementation. Makes linking (arm64) Chromium Framework with ld64.lld 17% faster. See also PR56121. No behavior change. Differential Revision: https://reviews.llvm.org/D128290

For non-mem-intrinsic and non-lifetime `CallBase`s, the current `isRemovable` function only checks if the `CallBase` 1. has no uses 2. will return 3. does not throw: https://github.com/llvm/llvm-project/blob/80fb7823367c1d105fcbc8f21b69205a0d68c859/llvm/lib/Transforms/Scalar/DeadStoreElimination.cpp#L1017 But we should also exclude invokes even in case they don't throw, because they are terminators and thus cannot be removed. While it doesn't seem to make much sense for `invoke`s to have an `nounwind` target, this kind of code can be generated and is also valid bitcode.

In HLSL vectors are ext_vectors in all respects except that they support a constructor style syntax for initializing vectors. This change adds a translation of vector constructor arguments into initializer lists.

This patch implements tile and fuse transformation for ops that implement the tiling interface. To do so, - `TilingInterface` needs a new method that generates a tiled implementation of the operation based on the tile of the result needed. - A pattern is added that replaces a `tensor.extract_slice` whose source is defined by an operation that implements the `TilingInterface` with a tiled implementation that produces the extracted slice in-place (using the method added to `TilingInterface`). - A pattern is added that takes a sequence of operations that implement the `TilingInterface` (for now `LinalgOp`s), tiles the consumer, and greedily fuses its producers iteratively.

Implement the support for %Stop asynchronous notification packet format in LLGS. This does not implement full support for non-stop mode for threaded programs -- process plugins continue stopping all threads on every event. However, it will be used to implement asynchronous events in multiprocess debugging. The non-stop protocol is enabled using QNonStop packet. When it is enabled, the server uses notification protocol instead of regular stop replies. Since all threads are always stopped, notifications are always generated for all active threads and copied into stop notification queue. If the queue was empty, the initial asynchronous %Stop notification is sent to the client immediately. The client needs to (eventually) acknowledge the notification by sending the vStopped packet, in which case it is popped from the queue and the stop reason for the next thread is reported. This continues until notification queue is empty again, in whic...
