--- Comment #11 from Christophe Lyon <clyon at gcc dot gnu.org> ---
I've added the -mbranch-cost=N option to the arm target, but compiling
/gcc.dg/tree-ssa/pr81588.c with 
-mcpu=cortex-a5 -mfpu=vfpv3-d16 -O2 -fdump-tree-reassoc1-details
-mbranch-cost=N -S -o pr81588.s

never produces the required trace in the dumps, whatever the value of N (0..3).

Switching to cortex-a9 always works.
