Re: [patch] [arm] ARM Cortex-M3/M4 tuning

[Ramana Radhakrishnan]

ChangeLog:

     2013-11-01  Julian Brown  <jul...@codesourcery.com>
     Joey Ye  <joey...@arm.com>
     * config/arm/arm.c (arm_cortex_m_branch_cost): New.
     (arm_v7m_tune): New.
     (arm_*_tune): Add comments for Sched adj cost.

List all names here please rather than a regexp.

     * config/arm/arm-cores.def (cortex-m4, cortex-m3):
     Use arm_v7m_tune tuning.


The ARM parts are ok but I'd like a testsuite maintainer to look at the 
testsuite changes before committing.

regards
Ramana
