Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446 2009-12-16 04:14:24 +08:00			`// RUN: %clang_cc1 -triple i386-unknown-unknown %s -emit-llvm-bc -o - \| opt -std-compile-opts \| llvm-dis \| grep 'ret i32 6'`
Teach Type::is[un]SignedIntegerType about enum decls. This allows the code generator to emit signed comparisons when needed for enum decl references. This implements test/CodeGen/enum.c. I think enums should be good now. llvm-svn: 41572 2007-08-30 01:48:46 +08:00
