Subject: [PATCH v7 0/5] perf: script: Intro capstone disasm engine to show instruction trace
This series introduces capstone disassembler engine to print instructions of
Intel PT trace, which was printed via the XED tool.
The advantages compared to XED tool:
* Support arm, arm64, x86-32, x86_64, s390 (more could be supported),
xed only for x86_64.
* More friendly to read. Immediate address operands are shown as symbol+offs.
Display raw instructions:
$ sudo perf record --event intel_pt//u -- ls
$ sudo perf script --insn-trace

v7:
- remove redundant space for raw instruction.
- rename sample__fprintf_insn() as sample__fprintf_insn_asm() and make it empty if libcapstone is not available.
v6:
- make '-F +disasm' fatal if libcapstone is not supported. (Adrian Hunter)
- display with perf version --build-options. (Adrian Hunter)
- exclude libcapstone from make_minimal. (Adrian Hunter)
v5:
- fixes and improments suggested by Adrian Hunter
v4:
- rename 'insn_disam' to 'disasm' (Adrian Hunter)
v3:
- fix s390 detection. (Thomas Richter)
v2:
- add a new field 'insn_disam' instead of changing the default output.
- preserve the old --xed option.
Changbin Du (5):
perf: build: introduce the libcapstone
perf: util: use capstone disasm engine to show assembly instructions
perf: script: add field 'disasm' to display mnemonic instructions
perf: script: add raw|disasm arguments to --insn-trace option
perf: script: prefer capstone to XED
