The attached patch reverts revision 183011, which changed the branch cost heuristics for Cortex-A15. This is because further benchmarking shows that there are significant regressions on some benchmarks which outweigh other performance gains. OK? Thanks, Matt gcc/ChangeLog: 2012-02-21 Matthew Gretton-Dann <matthew.gretton-dann@arm.com> Revert r183011 * config/arm/arm-cores.def (cortex-a15): Use generic Cortex tuning parameters. * config/arm/arm.c (arm_cortex_a15_tune): Remove. -- Matthew Gretton-Dann Principal Engineer, PD Software, ARM Ltd.
