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 %t %s`
Eliminate &&s in tests. - 'for i in $(find . -type f); do sed -e 's#\(RUN:.[^ ]\) && *$#\1#g' $i \| FileUpdate $i; done', for the curious. llvm-svn: 86430 2009-11-08 09:45:36 +08:00			`// RUN: grep '@llvm.used = .*@g0' %t`

IRgen support for attribute used. - PR3566 llvm-svn: 64492 2009-02-14 06:08:43 +08:00			`// RUN: grep '@llvm.used = .*@f1.l0' %t`
