Benchmarking Compilation Times
summary
A small tool that parses compiler timing output (LLVM/Clang clocks and GCC time reports) and builds a directory view showing per-directory and per-file compilation times, averages, totals and maxima so hotspots stand out. It estimates header impact by multiplying an include’s estimated cost by how many files include it (most impactful headers) and lists headers that don’t compile standalone. Not open source yet but will appear on the conference GitHub; real projects show surprises like single files requiring 8 GB of RAM to compile.
