This patch converts the function signatures to havea prototype for the situations where the test is not specific to K&R Cdeclarations. e.g., void func();becomes void func(void);This is the third batch of tests being updated (there are a significantnumber of other tests left to be updated).

I think we should either trackwhether that particular declaration is used (with isUsed scanning the entireredecl chain), or we should only have one flag for the entire redeclarationchain (perhaps by always looking at the flag on either the most recent decl orthe canonical decl). Modeling it as "is this declaration or any previousdeclaration used" is weird, and requires contortions like the loop at the endof Sema::MarkFunctionReferenced.llvm-svn: 193202 List of files: /llvm-project-15.0.7/clang/test/Sema/warn-variable-not-needed.c Tue, 22 Oct 2013 21:56:29 +0000 Rafael Espindola <rafael.espindola@gmail.com>
