• There is now one access note success remark and fix-it per declaration, not per attribute/modifier.
• Failure remarks have been rephrased to better emphasize the cause of the failure.
• The wording of other access note remarks and notes have been changed to follow a similar formula.
This will allow teams writing access notes to use -Raccess-note=all-validate to check that their access notes are correct, or teams working around problems to use -Raccess-note=failures or -Raccess-note=none to suppress diagnostics.
The LLVM rebranch added an “AllowUnknownKeys” setting to llvm::yaml::Input, which lets us rip out a lot of marginal code and encourages a broader rework of access note error diagnosis:
• Access note warnings and errors are now diagnosed as they’re found during YAML parsing
• They now have proper SourceLocs inside the .accessnotes file
• They’re now tested using -verify-additional-file instead of FileCheck
• A lot of gross duct tape is now gone
LLVM’s YAML support wants to show a hard error if an unknown string appears in an access note. Instead, emit a remark but load the parts of the access note we do understand to allow for future expansion of access notes.
