* Grow the X86FloatingPoint register map to hold 16 registers.Jakob Stoklund Olesen2011-06-271-5/+15
| | | | | | | This allows for more live scratch registers which is needed to handle live ST registers before return and inline asm instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133903 91177308-0d34-0410-b5e6-96231b3b80d8
* Distinguish early clobber output operands from clobbered registers.Jakob Stoklund Olesen2011-06-276-13/+26
| | | | | | | | | | | | | | | | | | | | | | Both become <earlyclobber> defs on the INLINEASM MachineInstr, but we now use two different asm operand kinds. The new Kind_Clobber is treated identically to the old Kind_RegDefEarlyClobber for now, but x87 floating point stack inline assembly does care about the difference. This will pop a register off the stack: asm("fstp %st" : : "t"(x) : "st"); While this will pop the input and push an output: asm("fst %st" : "=&t"(r) : "t"(x)); We need to know if ST0 was a clobber or an output operand, and we can't depend on <dead> flags for that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133902 91177308-0d34-0410-b5e6-96231b3b80d8

* PTX: Reverting implementation of i8.Dan Bailey2011-06-2511-546/+73
| | | | | | | | | | The .b8 operations in PTX are far more limiting than I first thought. The mov operation isn't even supported, so there's no way of converting a .pred value into a .b8 without going via .b16, which is not sensible. An improved implementation needs to use the fact that loads and stores automatically extend and truncate to implement support for EXTLOAD and TRUNCSTORE in order to correctly support boolean values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133873 91177308-0d34-0410-b5e6-96231b3b80d8
