New Revision: 308190
URL: http://llvm.org/viewvc/llvm-project?rev=308190&view=rev
Log:
[NFC] Refactor the Preprocessor function that handles Macro definitions and rename Arguments to Parameters in Macro Definitions.
- Extracted the reading of the tokens out into a separate function.
- Replace 'Argument' with 'Parameter' when referring to the identifiers of the macro definition (as opposed to the supplied arguments - MacroArgs - during the macro invocation).
This is in preparation for submitting patches for review to implement __VA_OPT__ which will otherwise just keep lengthening the HandleDefineDirective function and making it less comprehensible.
I will also directly update some extra clang tooling that is broken by the change from Argument to Parameter.
Hopefully the bots will stay appeased.
Thanks!
