Get optimization remarks from clang directly in your source code

Requirements

A recent version of clang

Tested with clang 9 and 10.

A compilation database

The tool needs to know how to compile your code and it does so using a compilation database. You can read about what they are and how to create them here.

If you're using cmake, there is a flag in the link telling you how to generate the compile_commands.json

Make has no built in way to generate a compilation database but you can generate one using compiledb as follows:

pip install compiledb compiledb make

A linux or mac computer

Currently the tool does not support on windows.
