The following test failures are regressions from GCC 4.8 for arm-none-eabi with
multilib flags that include "-march=armv8-a":

2013-04-02 Ian Caulfield <ian.caulfi...@arm.com>
Ramana Radhakrishnan <ramana.radhakrish...@arm.com>
* config/arm/arm-arches.def (armv8-a): Default to cortex-a53.
* config/arm/t-arm (MD_INCLUDES): Depend on cortex-a53.md.
* config/arm/cortex-a53.md: New file.
* config/arm/bpabi.h (BE8_LINK_SPEC): Handle cortex-a53.
* config/arm/arm.md (generic_sched, generic_vfp): Handle cortex-a53.
* config/arm/arm.c (arm_issue_rate): Likewise.
* config/arm/arm-tune.md: Regenerate
* config/arm/arm-tables.opt: Regenerate.
* config/arm/arm-cores.def: Add cortex-a53.
------------------------------------------------------------------------
If the tests aren't expected to use conditional instructions for armv8-a then
they should be skipped for use of that flag.
