  5. 16cab19 VNInfo cleanup. by Lang Hames · 16 years ago
  6. 210fc62 In some rare cases, the register allocator can spill registers but end up not utilizing registers at all. The fundamental problem is linearscan's backtracking can end up freeing more than one allocated registers. However, reloads and restores might be folded into uses / defs and freed registers might not be used at all. by Evan Cheng · 17 years ago

  13. f138201 Fix a crash in the pre-alloc splitter exposed by recent codegen changes. by Owen Anderson · 17 years ago
  14. b5f0ec3 Add TargetInstrInfo::isSafeToMoveRegisterClassDefs. It returns true if it's safe to move an instruction which defines a value in the register class. Replace pre-splitting specific IgnoreRegisterClassBarriers with this new hook. by Evan Cheng · 17 years ago
  15. 7411523 Pre-alloc splitting needs to be more careful to avoid inserting spills/restores by Owen Anderson · 17 years ago

  74. d0d0317 Committing a good chunk of the pre-register allocation live interval splitting pass. It's handling simple cases and appear to do good things.
