Bill Wendling	d336de318e	As Dan pointed out, movzbl, movsbl, and friends are nicer than their alias ... (movzx/movsx) because they give more information. Revert that part of the patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129498 91177308-0d34-0410-b5e6-96231b3b80d8	2011-04-14 01:46:37 +00:00
Bill Wendling	c6df9883da	Have the X86 back-end emit the alias instead of what's being aliased. In most ... cases, it's much nicer and more informative reading the alias. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129497 91177308-0d34-0410-b5e6-96231b3b80d8	2011-04-14 01:11:51 +00:00
Cameron Zwarich	ebe8173941	The x86-64 ABI says that a bool is only guaranteed to be sign-extended to a byte ... rather than an int. Thankfully, this only causes LLVM to miss optimizations, not generate incorrect code. This just fixes the zext at the return. We still insert an i32 ZextAssert when reading a function's arguments, but it is followed by a truncate and another i8 ZextAssert so it is not optimized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127766 91177308-0d34-0410-b5e6-96231b3b80d8	2011-03-16 22:20:18 +00:00
Cameron Zwarich	7be4b7ed75	Rename a test to be more inclusive. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127765 91177308-0d34-0410-b5e6-96231b3b80d8	2011-03-16 22:20:12 +00:00
