[llvm-commits] CVS: llvm/include/llvm/CodeGen/LiveIntervals.h

[Alkis Evlogimenos]

Changes in directory llvm/include/llvm/CodeGen:

LiveIntervals.h updated: 1.6 -> 1.7

---
Log message:

Change weight into a float so that we can take into account the
nesting level when computing it. Right now the allocator uses:

    w = sum_over_defs_uses( 10 ^ nesting level );

Diffs of the changes:  (+3 -2)
