--- Comment #8 from Alexandre Oliva <aoliva at gcc dot> ---
Hey, Vlad, I'm afraid bisection tells me r258390 caused a regression I'm seeing
on i686-linux-gnu.  hsa-regalloc now fails to compile in stage2:

../../gcc/hsa-regalloc.c: In function ‘void hsa_regalloc()’:
../../gcc/hsa-regalloc.c:728:1: error: unable to find a register to spill
