2011-04-17fold memcpy/set/move_chk to llvm.memcpy/set/move when the sizesChris Lattner
are trivial. This exposes opportunities earlier, and allows fastisel to do good things with these at -O0. This addresses rdar://9289468 - clang doesn't fold memset_chk at -O0 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129651 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar
- 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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8
