  To: gdb-patches; +Cc: toolchain-devel

Lift the code that GDB is using to generate dependencies on the fly and
port it over to the sim.  Now people shouldn't have to manually maintain
these in their Makefile's (for the most part).  Generated header files
still need to be manually tracked.

	* Makefile.in: Replace all dependency rules with a single rule
	for interp.o.

From: Mike Frysinger @ 2011-07-13  8:26 UTC (permalink / raw)
  To: gdb-patches; +Cc: toolchain-devel

Lift the code that GDB is using to generate dependencies on the fly and
port it over to the sim.  Now people shouldn't have to manually maintain
these in their Makefile's now.

	* Makefile.in: Delete all dependency rules.
	* aclocal.m4, configure: Regenerate.

	(DEPMODE, DEPDIR, depcomp, COMPILE.pre, COMPILE.post, COMPILE,
	POSTCOMPILE): New variables.
	(.c.o): Replace recipe with call to $(COMPILE) and $(POSTCOMPILE).
	Include dependency files, when using GNU Make.  Delete all
	dependency-only rules.
	* aclocal.m4: Include ../../config/depstand.m4.  Call
	ZW_CREATE_DEPDIR and ZW_PROG_COMPILER_DEPENDENCIES.
	(MAKE, GMAKE): New substs.

v2
	- delete more rules and import more gmake code from gdb to cover them
	- fix depcomp def
