Justin Holewinski	84f0bca9c1	[NVPTX] Rename registers %fl -> %fd and %rl -> %rd ... This matches the internal behavior of NVIDIA tools like libnvvm. llvm-svn: 213168	2014-07-16 16:26:58 +00:00
Justin Holewinski	0f70140107	[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. ... llvm-svn: 185174	2013-06-28 17:57:59 +00:00
Justin Holewinski	4ca961430f	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.
