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 2009-12-15 20:14:24 +00:00			`// RUN: %clang_cc1 -emit-llvm < %s \| grep puts \| count 4`
PR3248: Make sure the evaluate the operand of a sizeof when it has a VLA type. Adapted from patch by Tim Northover. llvm-svn: 69566 2009-04-20 03:21:44 +00:00
PR3247: Handle a couple of cases where we weren't emitting VLA sizes (and subsequently crashed). llvm-svn: 69567 2009-04-20 03:54:15 +00:00			`// PR3248`
