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 -emit-llvm-only -verify %s`
Avoid assert-crash in a case where the expression passed to EmitConstantExpr legitimately has side-effects (and needs to be generated as a non-constant). llvm-svn: 88767 2009-11-14 16:51:33 +08:00

Add a warning to catch a bug recently caught by code review, like this: t2.c:2:12: warning: use of logical && with constant operand; switch to bitwise & or remove constant [-Wlogical-bitwise-confusion] return x && 4; ^ ~ wording improvement suggestions are welcome. llvm-svn: 108260 2010-07-14 03:41:32 +08:00			`int y = x() && 0; // expected-warning {{use of logical && with constant operand}}`
