Subject: makefile dependency revamp
Date: Tue, 26 May 2009 03:38:00 -0000 [thread overview]
Message-ID: <20090526033837.GG1387@bubble.grove.modra.org> (raw)
The aim of this patch is to consistently generate dependencies despite
the fact that various versions of gcc differ in -MM output. Older
versions of gcc (eg. gcc-3.3) suppress duplicate dependencies, perhaps
by accident, due to emitting a dependency after checking whether a
header has a multiple inclusion macro guard. Newer versions of gcc
don't seem to do this, and I also found that a version of gcc-3.4.5 I
happened to have lying around didn't take note of the macro guard in
hashtab.h for some reason.
So, we need to sort and uniq the object files dependencies, but be
careful to keep the first dependency (the main .c file) in place for
makefile rules using $<. I found a few other tweaks were needed, most
notably the gas multi-obj dependencies now are not edited by dep.sed
and automake complained about a trailing backslash continuation
followed by a blank line.
bfd/
* dep-in.sed: Don't modify .o to .lo here. Output one filename
per line with all lines having continuation backslash. Prefix
first line with "A", following lines with "B".
* Makefile.am (DEP): Don't use dep.sed here.
(DEP1): Run $MKDEP on single files, modify .o to .lo here. Use
dep.sed here on dependencies, sort and uniq.
* Makefile.in: Regenerate.
opcodes/
* dep-in.sed: Don't modify .o to .lo here. Output one filename
per line with all lines having continuation backslash. Prefix
first line with "A", following lines with "B".
* Makefile.am (DEP): Don't use dep.sed here.
(DEP1): Run $MKDEP on single files, modify .o to .lo here. Use
dep.sed here on dependencies, sort and uniq.

continuation backslash. Prefix first line with "A", following

* Makefile.am (DEP): Don't use dep.sed here.
(DEP1): Run $MKDEP on single files, use dep.sed here on dependencies,
sort and uniq.
* Makefile.in: Regenerate.
I've trimmed the regenerated Makefile.am dependency changes from
the following diffs since I hit the 400k post limit..
