Hmm.. As well as everything depending on opt_global.h, how about having
it depend on something like ./compile, and build it along the lines of:
./compile: mumble
echo "#! /bin/sh" > compile.new
echo "exec ${CC} -c ${CFLAGS} ${PROF} $$*" >> compile.new
chmod a+x compile.new
move-if-change compile.new compile
./assemble: mumble
...
And then:
NORMAL_C= ./compile $<
..
NORMAL_S= ./assemble $<
etc.
The trick would be to keep ./compile and ./assemble up to date. Doing a
cmp and change or something might be enough since it would be evaluated at
each startup..
Then, the average compile output lines would look like this:
....
./compile kern_exec.c
./compile kern_fork.c
....
./assemble support.s
Of course, this would cost a shell startup for each file, but on the grand
scheme of things I'd be suprised if it was reliably measurable considering
all the nesting, recursion and other horrid things that happen in the make
environment.
