Description Filip Pizlo 2016-02-02 12:29:16 PST 
Current performance data suggests that LLVM's Greedy allocator runs slightly faster than IRC.  We can probably make IRC faster, but since everything in LLVM is systematically slower than in B3, it's a pretty good bet than our implementation of Greedy would be faster than LLVM's.
