Justin Holewinski	e04e4bdf71	[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. llvm-svn: 185177	2013-06-28 17:58:10 +00:00
Justin Holewinski	f8f7091722	[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	ae556d3ef7	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.
