Cameron Zwarich	ac106273d4	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. llvm-svn: 127766	2011-03-16 22:20:18 +00:00

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.
