[cfe-dev] [LLVMdev] [3.6 Release] RC3 has been tagged

[Jack Howarth]

I finally got around to testing this on a Bloomfield processor (Early
2009 MacPro 2x2.66 GHz dual-quad core) and the regressions from
http://llvm.org/bugs/show_bug.cgi?id=22589 are even more severe. For
10 runs of scimark2_1c built with "-O3 -march=native"...

llvm 3.5.1   1204.16+/-2.66 Mflops
3.6 branch   866.49+/-1.26 Mflops

Do you seriously want to ship with a 39% performance regression in a
major benchmark?
