[ARC] Disable compact casesi patterns for arcv2
gcc/
2016-05-09 Claudiu Zissulescu <claziss@synopsys.com>
* common/config/arc/arc-common.c (arc_option_optimization_table):
Remove compact casesi option.
* config/arc/arc.c (arc_override_options): Use compact casesi
option only for pre-ARCv2 cores.
* doc/invoke.texi (mcompact-casesi): Update text.
