The arm implementation of add_stmt_cost was added alongside
arm_builtin_vectorization_cost. At that time it was necessary
to override the latter when overriding the former, since
default_add_stmt_cost didn't indirect through the
builtin_vectorization_cost target hook:
int stmt_cost = default_builtin_vectorization_cost (kind, vectype,
misalign);
That was fixed by:
2014-06-06 Bingfeng Mei <b...@broadcom.com>
* targhooks.c (default_add_stmt_cost): Call target specific
hook instead of default one.
so the arm definition of add_stmt_cost is now equivalent
to the default.
Bootrapped & regression-tested on arm-linux-gnueabihf. OK to install?
