perf: script: add field 'disasm' to display mnemonic instructions
In addition to the 'insn' field, this adds a new field 'disasm' to display mnemonic instructions instead of the raw code. $ sudo perf script -F +disasm perf-exec 1443864 [006] 2275506.209848: psb: psb offs: 0 0 [unknown] ([unknown]) perf-exec 1443864 [006] 2275506.209848: cbr: cbr: 41 freq: 4100 MHz (114%) 0 [unknown] ([unknown]) ls 1443864 [006] 2275506.209905: 1 branches:uH: 7f216b426100 _start+0x0 (/usr/lib/x86_64-linux-gnu/ld-2.31.so) movq %rsp, %rdi ls 1443864 [006] 2275506.209908: 1 branches:uH: 7f216b426103 _start+0x3 (/usr/lib/x86_64-linux-gnu/ld-2.31.so) callq _dl_start+0x0 Signed-off-by: Changbin Du <changbin.du@huawei.com> Reviewed-by: Adrian Hunter <adrian.hunter@intel.com> Cc: changbin.du@gmail.com Cc: Thomas Richter <tmricht@linux.ibm.com> Cc: Andi Kleen <ak@linux.intel.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/r/20240217074046.4100789-4-changbin.du@huawei.com
