Function Call Tracing

Purpose

Trace all function calls in C/C++ programs with per-thread logs and Perfetto visualization.

Components

1. Instrumentation Library (trace_instrument.c)

Captures function entry/exit, writes per-thread logs.

Build:

gcc -c -fPIC trace_instrument.c -o trace_instrument.o
gcc -shared trace_instrument.o -o libtrace.so -ldl -lpthread

2. Perfetto Converter (trace_to_perfetto.cpp)

Converts logs to Chrome JSON for Perfetto UI.
