* [mlir][Python] Fix generation of accessors for OptionalMichal Terepeta2021-11-186-28/+42
| | | | | | | | | | | | | | | | | | | | | | Previously, in case there was only one `Optional` operand/result within the list, we would always return `None` from the accessor, e.g., for a single optional result we would generate: ``` return self.operation.results[0] if len(self.operation.results) > 1 else None ``` But what we really want is to return `None` only if the length of `results` is smaller than the total number of element groups (i.e., the optional operand/result is in fact missing). This commit also renames a few local variables in the generator to make the distinction between `isVariadic()` and `isVariableLength()` a bit more clear.

* [mlir] Convert NamedAttribute to be a classRiver Riddle2021-11-1854-220/+302
| | | | | | | | | NamedAttribute is currently represented as an std::pair, but this creates an extremely clunky .first/.second API.

| | | | | | | | | | | | | | algorithms. Also, mark these tests as compile-only. They actually are safe to run — notice that the code "runs" at constexpr-time in C++20, without error — because both of the input ranges are entirely filled with nullptr, so no matter how you shuffle the elements, they remain sorted and partitioned and heapified and everything. But there's no real reason to run them at runtime, so let's just avoid the distraction. Test cases that fail in trunk right now are commented out with `TODO FIXME`.

* [libc++] Enable <atomic> when threads are disabledLouis Dionne2021-11-1790-493/+272
| | | | | | | | | | | | | | | | | | | std::atomic is, for the most part, just a thin veneer on top of compiler builtins. Hence, it should be available even when threads are not available on the system, and in fact there has been requests for such support. This patch: - Moves __libcpp_thread_poll_with_backoff to its own header so it can be used in <atomic> when threads are disabled. - Adds a dummy backoff policy for atomic polling that doesn't know about threads. - Adjusts the <atomic> feature-test macros so they are provided even when threads are disabled. - Runs the <atomic> tests when threads are disabled. rdar://77873569 Differential Revision: https://reviews.llvm.org/D114109

* tsan: remove quadratic behavior in pthread_joinDmitry Vyukov2021-11-173-30/+34
| | | | | | | | | | | | | | | | | | | pthread_join needs to map pthread_t of the joined thread to our Tid. Currently we do this with linear search over all threads. This has quadratic complexity and becomes much worse with the new tsan runtime, which memorizes all threads that ever existed. To resolve this add a hash map of live threads only (that are still associated with pthread_t) and use it for the mapping. With the new tsan runtime some programs spent 1/3 of time in this mapping. After this change the mapping disappears from profiles. Depends on D113996. Reviewed By: vitalybuka, melver Differential Revision: https://reviews.llvm.org/D113997

This commit removes the initial asserts on invalid input and replaces those asserts with the error handling mechanism from those respective classes instead.
