Rename clang to clang-cc. Tests and drivers updated, still need to shuffle dirs. llvm-svn: 67602 2009-03-24 10:24:46 +08:00			`// RUN: clang-cc -emit-llvm %s -o - \|grep internal`
Improve merging of function declarations. Specifically: - When we are declaring a function in local scope, we can merge with a visible declaration from an outer scope if that declaration refers to an entity with linkage. This behavior now works in C++ and properly ignores entities without linkage. - Diagnose the use of "static" on a function declaration in local scope. - Diagnose the declaration of a static function after a non-static declaration of the same function. - Propagate the storage specifier to a function declaration from a prior declaration (PR3425) - Don't name-mangle "main" llvm-svn: 65360 2009-02-24 09:23:02 +08:00
