Tom Stellard	654d669e56	R600/SI: Remove SIISelLowering::legalizeOperands() ... Its functionality has been replaced by calling SIInstrInfo::legalizeOperands() from SIISelLowering::AdjstInstrPostInstrSelection() and running the SIFoldOperands and SIShrinkInstructions passes. llvm-svn: 225445	2015-01-08 15:08:17 +00:00
Tom Stellard	26cc18df43	R600/SI: Only fold immediates that have one use ... Folding the same immediate into multiple instruction will increase program size, which can hurt performance. llvm-svn: 225405	2015-01-07 22:18:27 +00:00
Tom Stellard	ef3b864a07	R600/SI: Teach SIFoldOperands to split 64-bit constants when folding ... This allows folding of sequences like: s[0:1] = s_mov_b64 4 v_add_i32 v0, s0, v0 v_addc_u32 v1, s1, v1 into v_add_i32 v0, 4, v0 v_add_i32 v1, 0, v1 llvm-svn: 225369	2015-01-07 19:56:17 +00:00
Tom Stellard	49f8bfdcb7	R600/SI: Add a stub GCNTargetMachine ... This is equivalent to the AMDGPUTargetMachine now, but it is the starting point for separating R600 and GCN functionality into separate targets. It is recommened that users start using the gcn triple for GCN-based GPUs, because using the r600 triple for these GPUs will be deprecated in the future. llvm-svn: 225277	2015-01-06 18:00:21 +00:00
Tom Stellard	6596ba7933	R600/SI: Add SIFoldOperands pass ... This pass attempts to fold the source operands of mov and copy instructions into their uses. llvm-svn: 222581	2014-11-21 22:06:37 +00:00
