[PATCH v3 0/1] Add Script for Dissecting QEMU Execution

Posted by Ahmed Karaman 3 years, 9 months ago

Hi,

This series adds the dissect.py script which breaks down the execution
of QEMU into three main phases:
code generation, JIT execution, and helpers execution.

It prints the number of instructions executed by QEMU in each of these
three phases, plus the total number of executed instructions.

To learn more about how the script works and for further usage
instructions, please check the "Dissecting QEMU Into Three Main Parts"
report posted as part of the "TCG Continuous Benchmarking" GSoC project.

Best regards,
Ahmed Karaman

v2->v3:
- Fix a misalignment in a comment line.
- Use tempfile.TemporaryDirectory() for handling intermediate files.
