* PTX: Reverting implementation of i8.Dan Bailey2011-06-251-2/+0
| | | | | | | | | | 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
* PTX: Add support for i8 type and introduce associated .b8 registersDan Bailey2011-06-241-0/+2
| | | | | | | | The i8 type is required for boolean values, but can only use ld, st and mov instructions. The i1 type continues to be used for predicates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133814 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | .file and .loc directives. Ideally, we would utilize the existing support in AsmPrinter for this, but I cannot find a way to get .file and .loc directives to print without the rest of the associated DWARF sections, which ptxas cannot handle. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133812 91177308-0d34-0410-b5e6-96231b3b80d8

* PTX: Add basic register spilling codeJustin Holewinski2011-06-201-0/+13
| | | | | | | | | | | | The current implementation generates stack loads/stores, which are really just mov instructions from/to "special" registers. This may not be the most efficient implementation, compared to an approach where the stack registers are directly folded into instructions, but this is easier to implement and I have yet to see a case where ptxas is unable to see through this kind of register usage and know what is really going on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133443 91177308-0d34-0410-b5e6-96231b3b80d8
