Add support for multiple-return values in inline asm. This should get inline asm working as well as it did previously with the CBE with the new MRV support for inline asm. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_23@51437 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-08More than just loads can read from memory: readonly calls like strlenChris Lattner
also need to be checked for memory modifying instructions before we can sink them. THis fixes the second half of PR2297. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50860 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-07Yet another nasty spiller bug.Evan Cheng
%ecx = op store %cl<kill>, (addr) (addr) = op %al It's not safe to unfold the last operand and eliminate store even though %cl is marked kill. It's a sub-register use which means one of its super-register(s) may be used below. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50794 91177308-0d34-0410-b5e6-96231b3b80d8
