Mode-Switching: Fix local array maybe uninitialized warning
There are 2 local array in function optimize_mode_switching. It will be
initialized conditionally at the beginning but then always consumed in
another loop. It may trigger the warning maybe-uninitialized, and may
result in build failure when enable werror, aka warning as error.
This patch will initialize the local array to zero explictly when
declaration.
Signed-off-by: Pan Li <pan2.li@intel.com>
gcc/ChangeLog:
* mode-switching.cc (entity_map): Initialize the array to zero.
(bb_info): Ditto.
