Hello Shane
I'm with Simon, this is very interesting stuff!
I'm wondering if we could make use of your data to figure out what headers we
should precompile. You said you extract a graph from the build: is there a way
to parse that graph to produce a list of headers most commonly included in a
given module?
We've had precompilation support in qmake for a decade, but apparently we use
that in exactly 3 modules...
