* PTX: Reverting implementation of i8.Dan Bailey2011-06-254-250/+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 Bailey2011-06-244-0/+250
| | | | | | | | 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

* PTX: Adjust rounding modesJustin Holewinski2011-06-176-22/+22
| | | | | | | | | | | | | | | * rounding modes for fp add, mul, sub now use .rn * float -> int rounding correctly uses .rzi not .rni * 32bit fdiv for sm13 uses div.rn (instead of div.approx) * 32bit fdiv for sm10 now uses div (instead of div.approx) Approx is not IEEE 754 compatible (and should be optionally set by a flag to the backend instead). The .rn rounding modifier is the PTX default anyway, but it's better to be explicit. All these modifiers should be available by using __fmul_rz functions for example, but support will need to be added for this in the backend.
