Hi,
Here is a series of patches which improves perf probe to add below features. I cleared some coding style issues.
- String support, which enables dynamic events to trace string variables instead of its address.
- Fixed-index array entry support, which allows user to trace an array entry with digit index, e.g. array[0].
- Global/static variable support, which allows user to trace global or static variables, as same as local one.
TODOs (possible features): - Support dynamic array-indexing (var[var2]) - Support force type-casting ((type)var) - Show what deta-structure member is assigned to each argument. - Better support for probes on modules - More debugger like enhancements(%next, --disasm, etc.)
Thank you,
---
