* Propagate the AlignStack bit in InlineAsm's to the Dale Johannesen2010-07-021-1/+5
| | | | | | | | | | | | | | | | | | | 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. llvm-svn: 107506

* Remove an unused variable. The call to getRoot has side-effects, soDuncan Sands2010-06-301-1/+0

* The hasMemory argument is irrelevant to how the argumentDale Johannesen2010-06-251-2/+2
| | | | | | | | | for an "i" constraint should get lowered; PR 6309. While this argument was passed around a lot, this is the only place it was used, so it goes away from a lot of other places. llvm-svn: 106893

* More changes for non-top-down fast-isel.Dan Gohman2010-06-211-11/+49
| | | | | | | | | | Split the code for materializing a value out of SelectionDAGBuilder::getValue into a helper function, so that it can be used in other ways. Add a new getNonRegisterValue function which uses it, for use in code which doesn't want a CopyFromReg even when FuncMap.ValueMap already has an entry for it. llvm-svn: 106422
