perf/core: Fix file name handling for start/stop filters

mathieupoirier · Ingo Molnar · commit 4059ffd09d69 · 2016-08-18T10:35:50.000+02:00
Binary file names have to be supplied for both range and start/stop filters but the current code only processes the filename if an address range filter is specified. This code adds processing of the filename for start/stop filters.
