Subject: [PATCH v2 0/5] perf: script: Intro capstone disasm engine to show instruction trace
Date: Wed, 17 Jan 2024 13:10:59 +0800 [thread overview]
Message-ID: <20240117051104.2147643-1-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 (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

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 'insn_disam' to display mnemonic instructions
perf: script: add raw|disam arguments to --insn-trace option
perf: script: prefer capstone to XED
