Scott Michel f0569be4a9 - Remove Tilmann's custom truncate lowering: it completely hosed over ... DAGcombine's ability to find reasons to remove truncates when they were not needed. Consequently, the CellSPU backend would produce correct, but _really slow and horrible_, code. Replaced with instruction sequences that do the equivalent truncation in SPUInstrInfo.td. - Re-examine how unaligned loads and stores work. Generated unaligned load code has been tested on the CellSPU hardware; see the i32operations.c and i64operations.c in CodeGen/CellSPU/useful-harnesses. (While they may be toy test code, it does prove that some real world code does compile correctly.) - Fix truncating stores in bug 3193 (note: unpack_df.ll will still make llc fault because i64 ult is not yet implemented.) - Added i64 eq and neq for setcc and select/setcc; started new instruction information file for them in SPU64InstrInfo.td. Additional i64 operations should be added to this file and not to SPUInstrInfo.td. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61447 91177308-0d34-0410-b5e6-96231b3b80d8		2008-12-27 04:51:36 +00:00
