Changes in directory llvm/test/CodeGen/X86:
test-pic-jtbl.ll updated: 1.4 -> 1.5
---
Log message:
Implement smarter algorithm for choosing which blocks to tail-merge.
See test/CodeGen/X86/test-pic-jtbl.ll for a case where it works well;
shaves another 10K off our favorite benchmark. I was hesitant about
this because of compile speed, but seems to do OK on a bootstrap.
