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 -fsyntax-only -verify %s`
Static variables and functions won't collide with standard library functions, so if we're declaring a static we should implicitly declare a library function by the same name (e.g., malloc, strdup). Fixes PR3592. llvm-svn: 64736 2009-02-17 11:23:10 +08:00

Fix PR3855. When we encounter an incompatible redeclaration of a library function, accept this declaration and pretend that we do not know that this is a library function. autoconf depends on this (broken) behavior. llvm-svn: 67541 2009-03-24 01:47:24 +08:00			`calloc(0, 0, 0);`
