  20. 857c4e0 VNInfo cleanup. by Lang Hames · 16 years ago
  21. c781a24 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 · 16 years ago

  29. 4350eb8 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
  30. 5734c94 Pre-alloc splitting needs to be more careful to avoid inserting spills/restores by Owen Anderson · 17 years ago

  82. 2306628 For now, don't split live intervals around x87 stack register barriers. FpGET_ST0_80 must be right after a call instruction (and ADJCALLSTACKUP) so we need to find a way to prevent reload of x87 registers between them. by Evan Cheng · 17 years ago
