a37ac9ff53 Don't add a default STACK_ALIGN (use the generic ABI alignment)
Implement calls to functions with byval arguments on X86

6e19896999 Objective-C was generating EH frame info like this:
"_-[NSString(local) isNullOrNil]".eh = 0
        .no_dead_strip  "_-[NSString(local) isNullOrNil]".eh

The ".eh" should be inside the quotes.

previously only done for 32-bit and smaller operands.

liveins and we let frontend solve type issue, not lowering code :)

X86InstrInfo::isReallyTriviallyReMaterializable knows how to handle
with the isReMaterializable flag so that it is given a chance to handle

visible, though it does keep CodeGen/X86/constant-pool-remat-0.ll from
making a copy of the constant pool on the stack.
