ac78a0645d [NVPTX] Calling conventions fix
Fix ABI handling for function
returning bool -- use st.param.b32 to return the value
and use ld.param.b32 in caller to load the return value.

1c07dae9fc [NVPTX] Remove i8 register class. PTX support for i8 (.b8, .u8, .s8) is rather poor and we're better off just ignoring it and letting LLVM expand all i8 ops out to i16.

b24fc1c7f7 [NVPTX] Remove support for SM < 2.0. This was never fully supported anyway.

49683f3c96 This patch adds a new NVPTX back-end to LLVM which supports code generation for NVIDIA PTX 3.0. This back-end will (eventually) replace the current PTX back-end, while maintaining compatibility with it.
The new target machines are:

nvptx (old ptx32) => 32-bit PTX
nvptx64 (old ptx64) => 64-bit PTX

The sources are based on the internal NVIDIA NVPTX back-end, and
contain more functionality than the current PTX back-end currently
provides.
