       is there any sort of tool that'll look at some executables debug info, and tell me how much of the binary is related to which source file?

       like if I compile foo.exe out of bar.cpp and baz.cpp, something that can tell me that foo.exe is 30% of the file, and baz.cpp is 60% of the file?

       I can do a sort of first-order approximation of it by looking at relative .o file sizes, but a file could easily have a lot of dead code removed in the linking stage so the .o would be big, but the final exe is small

       @foone you can parse the .map file with varying levels of success. eg https://github.com/nrbrook/zephyr-tools

       @foone I suppose you could write a quick and dirty tool to parse the map file ?
