The rule here is wrong, because %.qidl.c is never produced by the
commands.  The output is in the qidl-generated subdirectory, and that
cannot be expressed with pattern rules.

I was worried that this causes many greps on every invocation of the
Makefile---even though the way you hid them in makefile functions would
hide them from the "make" output.

However, this is not the case.  What happens is quite complex.
hw/foo.qidl.c (as opposed to hw/qidl-generated/foo.qidl.c) will never
exist, but it is a dependency of hw/foo.o, so it is always rebuilt
before it.  But it is not rebuilt on every invocation even though it
doesn't exist, because it only comes into play via implicit rules.

I think this is quite clever and does exactly what you want.  If you
want to keep the qidl-generated directory, I cannot imagine any other
way to do it.  However, please rename %.qidl.c to something QIDL-PP-% so
that it is clear that it is not a "real" file name.

If we decide this is too clever (and it's not all of it, it took me a
while to understand that Makefile functions are needed because
quiet-command expands to a @-prefixed command...), we can drop the
qidl-generated directory.

I think this $(call) is not what you want, you need just "@rm -f ..."

At the time I was in battle to the death with make to have it let me use
qidl-generated/ directories to store the output, but I don't care too
much anymore :P I think it's worth having if it doesn't cause any problems
though.

There is another way to do this (still using a "dummy" target)  that is a
bit less cryptic:

QIDL-PP-%: %.c qidl.h ...
    <grep and create %.qidl.c>

%.o: QIDL-PP-%
    <build normal or qidl CC>

But make detects that QIDL-PP-% is an intermediate target and removes
the *.qidl.c files after the build, which ends up forcing a re-build
each time. I played around with .INTERMEDIATE/.PRECIOUS directives to
have it keep the files but couldn't get it to cooperate, which is why I
ended up with the current approach.

Yes, and in fact this doesn't work. I hadn't noticed it because the old
files get clobbered by the code gen, so it only comes into play if you
take a QIDL'd file and then un-QIDL it (since the %.o rule sees the
.qidl.c file still there and tries to build it accordingly).

I'll go ahead and do a v5 with these changes in place.

How so?  Make does not even _know_ that %.qidl.c exists.

Sorry, wasn't remembering things correctly. That's how I had things
working *before* I'd switched to using qidl-generated subdirs, and it
was actually this:

 %.qidl.c: %.c qidl.h ...
     <grep and create %.qidl.c>
 
 %.o: %.c %.qidl.c
     <build normal or qidl CC>

which isn't doing anything special.

This is actually what I ended up going back to in v5 due to some issues
I noticed after fixing the bogus rm -f %.qidl.* call you caught. Using
.SECONDARY: addresses the issue I had with it deleting intermediate
(*.qidl.c) files.
