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 -o - %s \| FileCheck %s`
Use new getLinkage() method to correctly compute whether a variable has internal linkage. Fixes PR5433. llvm-svn: 89931 2009-11-26 10:52:12 +08:00

Mangle static variables with an extra name to distinguish them from non-static variables in the same TU. Fixes PR5966 for real this time; also reverts r92911, which had a incorrect fix. llvm-svn: 94352 2010-01-24 11:04:27 +08:00			`// CHECK: @_ZL1y = internal constant i32 20`
