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 -triple i386-unknown-unknown -emit-llvm -o %t %s`
Enable the new struct type builder now that the constant struct builder works. (The old code will still be there until we know that everything works well. llvm-svn: 77190 2009-07-27 15:31:55 +00:00			`// RUN: grep '@g0 = internal global %.truct.s0 { i32 3 }' %t \| count 1`
Emission of global variable initialializer was broken in rare situation where a tentative decl was emitted after the actual initialization. This occurs in some rare situations with static decls. - PR3613. - I'm not particularly happy with this fix, but I don't see a simpler or more elegant solution yet. llvm-svn: 65018 2009-02-19 05:36:41 +00:00
