Mike Ash	b8b59c4bac	[ExternalGenericMetadataBuilder] Add a test that validates built metadata against the runtime. ... We run the builder, then use a small program that converts the JSON output into C code that generates the data. Compile that into a bundle, then load it as the prespecializations library. Then scan all the entries in the table and compare them with what the runtime builds dynamically.	2024-01-31 17:03:27 -05:00
Mike Ash	ade4b8e989	[Runtime] Fix dyld call for Swift prespecialized data. ... Make our variables const to match the call signature, and do a weak check of the symbol before calling it.	2024-01-27 12:53:23 -05:00
Mike Ash	4341102c92	[Tools] Add a library to build specialized generic metadata out of process. ... This library uses GenericMetadataBuilder with a ReaderWriter that can read data and resolve pointers from MachO files, and emit a JSON representation of a dylib containing the built metadata. We use LLVM's binary file readers to parse the MachO files and resolve fixups so we can follow pointers. This code is somewhat MachO specific, but could be generalized to other formats that LLVM supports. rdar://116592577	2024-01-24 20:45:50 -05:00
