It should be easier to understand. v3: --- Cast 'struct hist_entry' to 'struct block_hist' in hist_entry__block_fprintf. Use symbol_conf.report_block to check if executing hist_entry__block_fprintf. v2: --- Keep standard perf diff format and display the 'Baseline' and 'Shared Object'. The output is sorted by "Baseline" and the basic blocks in the same function are sorted by cycles diff.
