* In inline asm treat indirect 'X' constraint as 'm'.Dale Johannesen2010-07-131-3/+5
| | | | | | | This may not be right in all cases, but it's better than asserting which it was doing before. PR 7528. llvm-svn: 108268

* Fix va_arg for doubles. With this patch VAARG nodes always contain theRafael Espindola2010-07-111-1/+2
| | | | | | | | | | | | | | | correct alignment information, which simplifies ExpandRes_VAARG a bit. The patch introduces a new alignment information to TargetLoweringInfo. This is needed since the two natural candidates cannot be used: * The 's' in target data: If this is set to the minimal alignment of any argument, getCallFrameTypeAlignment would return 4 for doubles on ARM for example. * The getTransientStackAlignment method. It is possible for an architecture to have argument less aligned than what we maintain the stack pointer. llvm-svn: 108072
* Reapply bottom-up fast-isel, with several fixes for x86-32:Dan Gohman2010-07-101-91/+22
| | | | | | | | | - Check getBytesToPopOnReturn(). - Eschew ST0 and ST1 for return values. - Fix the PIC base register initialization so that it doesn't ever fail to end up the top of the entry block. llvm-svn: 108039

* 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
