Dale Johannesen f1e309eb48 Propagate the AlignStack bit in InlineAsm's to the ... PrologEpilog code, and use it to determine whether the asm forces stack alignment or not. gcc consistently does not do this for GCC-style asms; Apple gcc inconsistently sometimes does it for asm blocks. There is no convenient place to put a bit in either the SDNode or the MachineInstr form, so I've added an extra operand to each; unlovely, but it does allow for expansion for more bits, should we need it. PR 5125. Some existing testcases are affected. The operand lists of the SDNode and MachineInstr forms are indexed with awesome mnemonics, like "2"; I may fix this someday, but not now. I'm not making it any worse. If anyone is inspired I think you can find all the right places from this patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107506 91177308-0d34-0410-b5e6-96231b3b80d8		2010-07-02 20:16:09 +00:00
