Use an explicit unsigned comparison for span index checks ( #83150 )
...
LLVM ought to be able to do this transformation for us, but it currently fails to do so. We can code around it easily enough. https://github.com/swiftlang/swift/pull/83172 has a better long-term fix.

Optimization pass over String and UTF8Span's allASCII helper ( #82540 )
...
This ranges between parity (for very small strings) and 5x faster (for
32-63B strings) in benchmarking on M1 MBP. For largeish strings it
delivers a roughly 2x speedup; further increase in blocksize nets a
small win in microbenchmarks that I do not expect would translate to
real world usage due to codesize impact and the fact that most strings
are smallish.
There's some opportunity for further work here; in particular, if people
start building Swift for a baseline of AVX2 or AVX512, we should have
paths for that (and we should also implement them if/when we get better
multiversioning dispatch machinery in the language). Span adoption would
be interesting. It's likely we should have a dedicated "small core"
implementation that uses only aligned accesses. Still, this is a
significant improvement as-is, and we should land it.

Mark the concrete SIMD/Scalar comparisons disfavored ( #82686 )
...
Adding the concrete versions (https://github.com/swiftlang/swift/pull/81892 ) introduced an ambiguity for concrete vec .<= .zero comparisons; previously the concrete SIMD .<= SIMD operation would win (because we didn't have a concrete overload for SIMD .<= SIMD.Scalar). We can restore the old behavior by marking these disfavored.

[Swiftify] Adjust _SwiftifyImport invocation to align with the signature
...
of the macro in the currently laoded macro module
Stdlib macros are shipped with the SDK, so we need to make sure that the
way we invoke the macro matches the version of the macro in the SDK.
This patch skips the `spanAvailability` parameter if it isn't present.
There's no good way to test this, because we will always pick up the
current macro in our llvm-lit test suite, but I've tested it manually.
