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 -O1 -emit-llvm -o %t %s`
Eek! getDeclAlign sometimes returned alignment in bits. - Renamed to getDeclAlignInBytes since most other query functions work in bits. - Fun to track down as isIntegerConstantExpr was getting it right, but Evaluate() was getting it wrong. Maybe we should assert they compute the same thing when they succeed? llvm-svn: 64828 2009-02-18 06:16:19 +08:00			`// RUN: grep 'ret i32 4' %t`
