--- Comment #8 from acab at digitalfuture.it ---
Bisecting across llvm major releases was a total pain in the arse, but then
I've realized that the bug was fixed recently in the 3.6 branch so I've given
up.

If it helps, i can tell you that the bug was fixed here (mind you good and bad
are reversed):
$ git bisect good
b5344bfff41583c00026e321d6831d4e8790b309 is the first bad commit
commit b5344bfff41583c00026e321d6831d4e8790b309

    R600/SI: Add VCC as an implict def of SI_KILL

    When SI_KILL has a register operand, its lowered form writes to vcc.
