Added Mac OS X assembler style conditional assembly. I may come back and see if I can clean this up a bit more and do way with the TheCondState and just use the top element on the TheCondStack if not empty. Also may tweak the code around ParseConditionalAssemblyDirectives() to simplify the AsmParser code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78423 91177308-0d34-0410-b5e6-96231b3b80d8 2009-08-07 22:46:00 +00:00			`# RUN: llvm-mc -triple i386-unknown-unknown %s -I %p \| FileCheck %s`

MC/AsmParser: Attempt to constant fold expressions up-front. This ensures we avoid fixups for obvious cases like '-(16)'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96064 91177308-0d34-0410-b5e6-96231b3b80d8 2010-02-13 01:28:07 +00:00			`# CHECK: .byte 2`
