Hi Ingo,
Here are several updates of perf-probe. This updates includes data structure accessing support --list option enhancement and --dry-run option support.
- --dry-run allows users to run perf-probe just for checking that the command works correctly.
- --list option enhancement allows user to check where the probes are put on (with filename/line number).
- data structure accessing support allows user to trace the contents of local variables/function parameters.
Long-term TODOs (future features): - Enhance probe-finder to decode call frame instructions. - Support tracing static variables (non global) - Support variable basic types from debuginfo (e.g. char, int, ...) - Support array element (var[N]) - Support string/dynamic arrays (*var, var[N..M]) - Support the type of return value - Support force type-casting ((type)var) - Support sys_perf_counter_open (for non-root users) - Support dynamic array-indexing (var[var2])
Miscs: - Better support for probes on modules - More debugger like enhancements(%next, --disasm, etc.)
Thank you,
---
