Heh.
Longest line is drivers/.../ia_css_ynr.host.c:71 (27785kB)
yeah, that's a single line that expands to 27MB in size.
And yes, that line is one single min(...) expression with arguments
that are then in turn macros with other nested min/max arguments.
See also drivers/staging/media/atomisp/pci/sh_css_frac.h.
On my fairly beefy (admittedly more cores than single-thread) machine,
just generating the preprocessor file takes just under 20s.
Building the object file is actually faster at "only" 8.5s for that
one file, because it uses the built-in preprocessor and never writes
it out, and most of the actual preprocessing result is trivial stuff
that gets thrown away immediately.
