- 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.
