…t need to pattern match and varies with asserts.
- Revise '// Prints' comments style like the other stdlib files - Remove verbose string interpolations and extra spaces - Remove some unneeded parentheses - Replace the majority of ' : ' with ': ' - Fix wrong indentation - Keep files with a single empty line at the end
… in C++ `libInternalSwiftSyntaxParser.dylib` currently doesn’t link against `SwiftExperimentalStringProcessing`, so it can’t use the regex lexing functions defined within. This caused SwiftSyntax to fail if the source code contained regex literals. Implement a fallback regex lexing function in C++ and use it for SwiftSyntax parsing. rdar://93580240 Co-authored-by: Rintaro Ishizaki <[email protected]>
Otherwise we can duplicate linker flags across input binaries, which can result in very large linkerr invocation commands. Resolves swiftlang#58380
The number of dependencies isn't super important for this test - it is just checking paths are correctly remapped. Remove the check for the number of dependencies.
The utility provides a standard way for backwards traversing a region of a function constrained by a predicate (isInRegion) starting from some root blocks. It exposes a visit function for post-order and iterable collections for post-order and reverse post-order. Adding corresponding pre-order functionality will be straightforward.
The new optimistic, iterative backward reachability is optimized to do as little work as possible. Only blocks not all of whose successors are kills participate in the worklist at all. The blocks within that discovered set are visited via a worklist which tracks blocks which have been found to be unreachable at begin and whose unreachable-at-begin-ness must be propagated into unreachable-at-end-ness of its predecessors. rdar://92545900
The new utility finds access scopes which are barriers by finding access scopes which themselves contain barriers. This is necessary to (1) allow hoisting through access scopes when possible (i.e. not simply treating all end_access instructions as barriers) and (2) not hoist into access scopes that contain barriers and in so doing introduce exclusivity violations.
Instead of doing one or two non-iterative BackwardReachability runs, do a single run of IterativeBackwardReachability. During that, pause after discovery/local dataflow and use VisitBarrierAccessScopes to determine which end_access instructions in the discovered region are barriers. Add those instructions as kills to the dataflow. Finally run the global dataflow. Enables SSADestroyHoisting to hoist destroys over loops. Addresses a correctness issue where access scopes which were open at barrier blocks were not promoted to barriers, resulting in destroy_addrs getting hoisted into unrelated access scopes.

…is `Any` Computing type relations to 'Any' is not very enlightning because everything would be convertible to it. If the contextual type is 'Any', just report all type relations as 'Unknown'. rdar://64812321 rdar://84684686
