perf hists: Add block_info in hist_entry
The block_info contains the program basic block information, i.e, contains the start address and the end address of this basic block and how much cycles it takes. We need to compare, sort and even print out the basic block by some orders, i.e. sort by cycles. For this purpose, we add block_info field to hist_entry. In order not to impact current interface, we creates a new function hists__add_entry_block. v6: --- Remove the 'ops' argument in hists__add_entry_block Signed-off-by: Jin Yao <yao.jin@linux.intel.com> Reviewed-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jin Yao <yao.jin@intel.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1561713784-30533-3-git-send-email-yao.jin@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
