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 < %s \| grep 'shufflevector' \| count 1`
Make __builtin_shufflevector and -ftrapv work correctly together. PR9945. llvm-svn: 131611 2011-05-19 08:37:32 +08:00			`// RUN: %clang_cc1 -emit-llvm -ftrapv < %s \| grep 'shufflevector' \| count 1`
Implementation of __builtin_shufflevector, a portable builtin capable of expressing the full flexibility of the LLVM shufflevector instruction. The expected immediate usage is in *mmintrin.h, so that they don't depend on the mess of gcc-inherited (and not completely implemented) shuffle builtins. llvm-svn: 51113 2008-05-15 03:38:39 +08:00			`typedef int v4si __attribute__ ((vector_size (16)));`
