This PR replaces eligible uses of
@_silgen_name
instdlib/
with@abi
. Because the API digester has a better understanding of@abi
than@_silgen_name
, this also affects the output of API digester tests run on the standard library; it should typically describe changes more accurately than it did before.This PR also includes two commits with macro-related tests that were originally part of #80383 but cannot be merged without a SwiftSyntax change (either swiftlang/swift-syntax#3026 or the changes that will be made if SE-0476 is accepted).
Standard library reviewers: Review the final commit; ignore the others. You might also want to search the standard library for uses of
@_silgen_name
that I might have missed. (Remember,@abi
is not designed to replace uses of@_silgen_name
to assign an arbitrary string symbol, likeswift_stdlib_getDescription
.)
