Subject: [PATCH v7 0/5] perf: script: Intro capstone disasm engine to show instruction trace
Date: Tue, 6 Feb 2024 19:29:24 +0800 [thread overview]
Message-ID: <20240206112929.1035548-1-changbin.du@huawei.com> (raw)
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:

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
