[llvm-commits] CVS: llvm/lib/Target/Sparc/SparcRegInfo.cpp

[Chris Lattner]

Changes in directory llvm/lib/Target/Sparc:

SparcRegInfo.cpp updated: 1.74 -> 1.75

---
Log message:

  - Two minor improvements to the MachineInstr class to reduce footprint and
    overhead: Merge 3 parallel vectors into 1, change regsUsed hash_set to be a
    bitvector.  Sped up LLC a little less than 10% in a debug build!
