clang-time-trace-analyzer

Analyze clang time-trace JSONs. Application iterates through files and directories for time-trace JSONs to concatenate them in one output.

Features:

generation of flame graph from single JSON file
viewing multiple JSON files at once in KCachegrind

Examples

Example output of analyze tool: sorted files.

Example output of flamegraph tool:

After running callgrind tool KCachegrind will be used to present results. Example view can be seen in following screen:

Running application

To run application execute python3 -m ctta --help to receive cmd help.

Showing multiple files placed in pointed directory in KCachegrind:

python3 -m ctta callgrind -d /path/to/build/dir

Instrumenting clang compiler

To instrument clang to generate time trace files you have to pass -ftime-trace flag to the compiler. It can be achieved by following steps:

through CMakeLists.txt: set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -ftime-trace")
through cmake cmd line: cmake -DCMAKE_CXX_FLAGS="-ftime-trace" .
