Add self-tracing tooling and standardize trace macros#72
Merged
Conversation
Add scripts to automate TRACE_ macro insertion and identify noisy traces: - scripts/insert_trace.py: libclang-based tool to insert/remove TRACE_FUNCTION_CAT macros with dry-run default, --commit to apply, --remove to clean and re-insert, .trace_ignore support, single-statement function skipping - scripts/find_noisy_traces.py: streaming analyzer for high-frequency trace events - .trace_ignore: functions too hot to trace (SAX callbacks, flame tree building, etc) Standardize all existing manual TRACE_SCOPE_CAT calls to TRACE_FUNCTION_CAT and remove redundant mid-function traces that the automated tool replaces.
