7e6565112b [NVPTX] Rename registers %fl -> %fd and %rl -> %rd
This matches the internal behavior of NVIDIA tools like libnvvm.

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.

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.
