[FFmpeg-devel] [PATCH 1/2] checkasm/hevc_add_res: prepare test data only if the fuction is not tested

[Linjie Fu]

check_func will return NULL for functions that have already been tested. If
the func is tested and skipped (which happens several times), there is no
need to prepare data(randomize_buffers and memcpy).

Move relative code in compare_add_res(), prepare data and do check only if
the function is not tested.
