[Tom Tromey]

This removes manual dependencies for the c-family .o files.

	* Makefile.in (c-family/cppspec.o, c-family/c-common.o)
	(c-family/c-cppbuiltin.o, c-family/c-dump.o, c-family/c-format.o)
	(c-family/c-gimplify.o, c-family/c-lex.o, c-family/c-omp.o)
	(c-family/c-opts.o, c-family/c-pch.o, c-family/c-ppoutput.o)
	(c-family/c-pragma.o, c-family/c-pretty-print.o)
	(c-family/c-semantics.o, c-family/c-ada-spec.o)
	(c-family/array-notation-common.o, c-family/stub-objc.o): Remove.

[PATCH v2 08/18] convert the ObjC++ front end to automatic dependencies

[Tom Tromey]

This converts the ObjC++ front end.

Now we can finally remove the *_H macros from cp/Make-lang.in.

	* Make-lang.in (CXX_TREE_H, CXX_PARSER_H, CXX_PRETTY_PRINT_H):
	Remove.

	* Make-lang.in (START_HDRS, cc1objplus-checksum.o)
	(objcp/objcp-lang.o, objcp/objcp-decl.o
	(objcp/objc-runtime-shared-support.o)
	(objcp/objc-gnu-runtime-abi-01.o objcp/objc-next-runtime-abi-01.o)
	(objcp/objc-next-runtime-abi-02.o, objcp/objcp-act.o)
	(objcp/objc-encoding.o, objcp/objc-map.o): Use COMPILE and
	POSTCOMPILE.  Remove explicit dependencies.

	(gfortranspec.o): Remove.
	(CFLAGS-fortran/gfortranspec.o): New variable.
	(GFORTRAN_D_OBJS): Update.

[PATCH v2 17/18] remove last definition of CROSS_FLOAT_H

[Tom Tromey]

There is a single definition of CROSS_FLOAT_H in the source.
As far as I can tell, this is never used anywhere.
So, this patch removes it.

	* config/mcore/t-mcore (CROSS_FLOAT_H): Remove.

[PATCH v2 13/18] convert LTO to automatic dependencies

[Tom Tromey]

This converts LTO.

This also fixes a latent buglet in lto/Make-lang.in.  lto_OBJS should
hold all the objects for a language, but LTO never defined this.

	* Make-lang.in (LTO_H, LINKER_PLUGIN_API_H, LTO_TREE_H)
	(lto/lto-lang.o, lto/lto.o, lto/lto-partition.o)
	(lto/lto-object.o): Remove.

[PATCH v2 12/18] convert the Go front end to automatic dependencies

[Tom Tromey]

This converts Go.

It renames gospec.o to go/gospec.o, for uniformity and so we can
remove an explicit rule.

It defines go_OBJS, to conform to the documented Make-lang.in
conventions, and to ensure that Go objects are given the correct
order-only dependencies on generated files.

	* Make-lang.in (gospec.o): Remove.
	(CFLAGS-go/gospec.o): New variable.
	(GCCGO_OBJS): Update to use go/gospec.o.
	(go_OBJS): Define.
	(GO_SYSTEM_H, GO_C_H, GO_LINEMAP_H, GO_LEX_H, GO_PARSE_H)
	(GO_GOGO_H, GO_TYPES_H, GO_STATEMENTS_H, GO_EXPRESSIONS_H)

	(go/parse.o, go/runtime.o, go/statements.o, go/types.o)
	(go/unsafe.o): Remove.
	(CFLAGS-go/go-gcc.o, CFLAGS-go/go-linemap.o): New variables.
	(go/%.o: go/gofrontend/%.cc): Use COMPILE and POSTCOMPILE.

[PATCH v2 00/18] resurrect automatic dependencies

[Tom Tromey]

This is a refresh of my series to resurrect automatic dependency
tracking.  v1 was posted here:

    http://gcc.gnu.org/ml/gcc-patches/2013-07/msg01218.html

Compared to v1:

* I ran the "hanging test" using GNU make 3.81 on each revision, as
  detailed:

    http://gcc.gnu.org/ml/gcc-patches/2013-07/msg01267.html

* I introduced a POSTCOMPILE step.  This helps cope with dependency
  issues if gcc is interrupted.  See:

    http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35697

  This came up during review of the original patch, ages ago.

* I've rebased a few times so that it applies to current trunk.


Ok?

Tom

[PATCH v2 01/18] clean up SHLIB so subshells are not needed

[Tom Tromey]

This changes the handling of SHLIB so that it is inlined into
DRIVER_DEFINES.  This is ok because SHLIB is defined in a Makefile
fragment that is included by the generated Makefile.

The rationale for this is that it simplifies some .o targets, so that
we can share more code.

	* Makefile.in (DRIVER_DEFINES): Use $(and), not shell code,
	to add -DENABLE_SHARED_LIBGCC.
	(gcc.o): Don't use subshell.

	* Make-lang.in (c/gccspec.o): Don't use subshell.

	* Make-lang.in (g++spec.o): Don't use subshell.

	* Make-lang.in (gfortranspec.o): Don't use subshell.

	* Make-lang.in (gospec.o): Don't use subshell.

	* Make-lang.in (jvspec.o): Don't use subshell.

[PATCH v2 07/18] convert the ObjC front end to automatic dependencies

[Tom Tromey]

This converts the ObjC front end.

Note that there is a latent possible bug in this code -- both ObjC and
ObjC++ define START_HDRS.  Whichever is included last, wins; if they
are out of sync, then something could break.  This possibility is
eliminated by this series.

	* Make-lang.in (START_HDRS, cc1obj-checksum.o, objc/objc-lang.o)
	(objc/objc-runtime-shared-support.o)
	(objc/objc-gnu-runtime-abi-01.o, objc/objc-next-runtime-abi-01.o)
	(objc/objc-next-runtime-abi-02.o, objc/objc-act.o)
	(objc/objc-encoding.o, objc/objc-map.o): Remove.

[PATCH v2 04/18] add configury

[Tom Tromey]

This adds the configury needed for automatic dependency tracking.  It
also adds some bits to the Makefile so we can begin converting
(removing) explicit dependencies.

	* Makefile.in (CCDEPMODE, DEPDIR, depcomp, COMPILE.base)
	(COMPILE, POSTCOMPILE): New variables.
	(.cc.o .c.o): Use COMPILE, POSTCOMPILE.
	(DEPFILES): New variable.
	Include ".Po" files.
	* configure.ac: Add checks for dependency checking.
	* configure, aclocal.m4: Regenerate.

[PATCH v2 05/18] convert the C front end to automatic dependencies

[Tom Tromey]

This converts the C front end.

Note that this fixes a latent bug in gcc/Makefile.in's definition of
C_TREE_H.  This is needed to avoid breaking this build with this
patch.

	* Makefile.in (C_TREE_H): Reference c/c-tree.h.

	* Make-lang.in (c/gccspec.o): Remove.
	(CFLAGS-c/gccspec.o): New variable.
	(cc1-checksum.o, C_TREE_H, c/c-aux-info.o, c/c-convert.o)
	(c/c-decl.o, c/c-errors.o, c/c-lang.o, c/c-objc-common.o)
	(c/c-parser.o, c/c-typeck.o, c/c-array-notation.o): Remove.

[PATCH v2 06/18] convert the C++ front end to automatic dependencies

[Tom Tromey]

This converts the C++ front end.

This renames g++spec.o to cp/g++spec.o for uniformity.
This lets us remove an explicit rule.

This patch does not remove various *_H macros from cp/Make-lang.in.
These are still needed by ObjC++.  They're removed by a later patch.

	* Make-lang.in (g++spec.o): Remove.
	(CFLAGS-cp/g++spec.o): New variable.
	(GXX_OBJS): Reference cp/g++spec.o.
	(cc1plus-checksum.o, cp/lex.o, cp/cp-array-notation.o)
	(cp/cp-lang.o, cp/decl.o, cp/decl2.o, cp/cp-objcp-common.o)
	(cp/typeck2.o, cp/typeck.o, cp/class.o, cp/call.o)
	(cp/friend.o, cp/init.o, cp/method.o, cp/cvt.o, cp/search.o)
	(cp/tree.o, cp/ptree.o, cp/rtti.o, cp/except.o, cp/expr.o)
	(cp/pt.o, cp/error.o, cp/repo.o, cp/semantics.o, cp/dump.o)
	(cp/optimize.o, cp/mangle.o, cp/parser.o, cp/cp-gimplify.o)
	(cp/name-lookup.o, cp/cxx-pretty-print.o): Remove.

[PATCH v2 18/18] remove unused macros

[Tom Tromey]

I used this perl script to find unused _H macros in the Makefile.  I
deleted the definitions it reported and re-ran the script, until there
was no more output.

The script also makes note of _H variables which are used but never
defined.  That is how I found the TREE_GIMPLE_H use, fixed earlier in
the series.

Once Ada and the various config files are migrated to automatic
dependencies, we can run this script again and remove more things.

================================================================

while (<>) {
    chomp;
    if (m/^(([A-Z0-9_]+)_H)\s*:?=\s/) {
	$saw_def{$1} = $ARGV . ":" . $.;
    }

    while (m/\$[({](([A-Z0-9_]+)_H)[)}](.*)/) {
	$saw_use{$1} = 1;
	$_ = $3;
    }
} continue {
    close ARGV if eof;
}

foreach $key (sort keys %saw_use) {
    if (! defined $saw_def{$key}) {
	print "use without a def of ", $key, "\n";
    }
}

foreach $key (sort keys %saw_def) {
    if (! defined $saw_use{$key}) {
	print $saw_def{$key}, ": no use of ", $key, "\n";
    }
}

[PATCH v2 16/18] remove last reference to TREE_GIMPLE_H

[Tom Tromey]

There is a single reference to TREE_GIMPLE_H in the source tree.
Since it is not defined anywhere, we might as well remove the use.

	* config/i386/t-i386 (i386.o): Don't use TREE_GIMPLE_H.

[PATCH v2 15/18] make out_object_file rule use automatic dependencies

[Tom Tromey]

This is a small change to make out_object_file use automatic
dependencies.

	* Makefile.in ($(out_object_file)): Use COMPILE and POSTCOMPILE.

[PATCH v2 14/18] remove explicit dependencies

[Tom Tromey]

This removes most of the explicit dependencies for host objects.
It also fixes a few rules to use $(COMPILE) in the process.

build objects are not affected, and are one reason that the various _H
macros are not yet removed.

[PATCH v2 02/18] update generated_files

[Tom Tromey]

A few generated files were not mentioned in the generated_files
variable.  This fixes the problem.

	* Makefile.in (generated_files): Add options.h,
	target-hooks-def.h, insn-opinit.h,
	common/common-target-hooks-def.h.

[PATCH v2 03/18] move generated_files order-only dependency later

[Tom Tromey]

There is an order-only dependency in gcc/Makefile.in that tries to
build the generated files before compiling regular objects.  However,
this appears too early, and so at the time it is seen by make,
GCOV_OBJS and GCOV_DUMP_OBJS have not yet been set.

This patch fixes the problem and prevents any future problems of this
nature by moving the order-only dependency to the end of Makefile.in.

This also adds lto-wrapper.o to ALL_HOST_BACKEND_OBJS.

	* Makefile.in (ALL_HOST_BACKEND_OBJS): Add lto-wrapper.o.
	($(ALL_HOST_OBJS)): Move order-only dependency to end
	of file.

[PATCH v2 09/18] convert the Java front end to automatic dependencies

[Tom Tromey]

This converts the Java front end.

We also rename jvspec.o to java/jvspec.o, for uniformity; this lets us
remove an explicit rule.

	(CFLAGS-java/jvspec.o): New variable.

I'll make the change, but please note that this is how it was before my
patch.  This fact is obscured by the way diff chooses to show the
changes.  Ordinarily I would not make a reformatting change like this at
the same time as a non-formatting change.
