[-- Attachment #1: Type: text/plain, Size: 1259 bytes --]

The following is the current state-of-the art of my autoconf-2.5x 
conversion of the gcc/gdb/binutils repositories. It updates the 
following directories:

common:	libiberty
src:		bfd binutils gas gdb gprof ld mmalloc opcodes rda sim utils
gcc:		boehm-gc fastjar gcc libf2c libffi libjava libobjc libstdc++-v3 
zlib

It does *not* update the following directories:

common:	include texinfo config etc contrib
src:		blt cgen cpu dejagnu expect intl itcl iwidgets libgloss libgui 
newlib readline tcl tk winsup sid"
gcc:		libbanshee libchill libio libmudflap libstdc++"

I used the following versions of the various tools:

libtool:		1.4e (top-of-tree, with the attached patch)
autoconf:		2.57 (with the attached patch)
automake:	1.7.2
gettext:		0.11.5
autogen:		5.5

The attached archive contains the following files:

ChangeLog:
setup.sh:			Script to convert to autotools-2.5x and build an uberbaum 
tree
autoconf.txt:		Fixes to autoconf-2.57 required by this patch.
common-diffs.txt	Patches to directories shared by 'src' and gcc.
gcc-diffs.txt		Patches to the gcc directories.
libtool-diffs.txt		Patch to libtool-1.4e required by this patch.
src-diffs.txt		Patches to the 'src' directories.
top-diffs.txt		Patches to top-level files in both 'src' and gcc.

2003-01-07  Klee Dienes  <kdienes@apple.com>

	* configure.in: Allow AS_FOR_TARGET explicitly, to avoid confusing
	automake (which thinks it's a macro).
	Use $target, $build, and $host to get canonical tuples, rather
	than $target_alias, $build_alias, and $host_alias.  Don't pass
	--cache= arguments to sub-configures (they'll default to not using
	a cache file).
	(baseargs): Strip quotes from single-quoted strings in
	ac_configure_args.
	(libstdcxx_flags): Assume that testsuite_flags will not prepend a
	space; always have a single space between arguments, even if
	testsuite_flags returns an empty string.

	* config.if:  Use $target, $build, and $host to get canonical
	tuples, rather than $target_alias, $build_alias, and $host_alias.

	* Makefile.tpl: Echo the sub-configures before executing them.
	Pass LDFLAGS to sub-makes via the environment.
	
	* .cvsignore: Add autom4te.cache.

To run, first read through setup.sh, and make sure it won't do anything 
you don't want it to do on your system.  Then set the values of 
src_gcc, src_src, and dst_root, and run setup.sh.    The script will 
rsync the checked-out gcc and src sources into a new directory, apply 
the patches, and run autoreconf on all the appropriate directories.

I've built directory on i386-unknown-linux-gnu native, targetted to 
powerpc-unknown-linux-gnu, and natively on i686-pc-cygwin (I got some 
errors building winsup on cygwin, but they were the same errors I got 
from the unmodified sources).  I've *not* run extensive tests on the 
resulting builds --- I'm willing to do that, but it seemed a bit early 
at this stage.

I did not attempt to make the patches compatible with both 
autoconf-2.13 and autoconf-2.5x --- I suspect that would be a 
significant challenge, and converting to automake-1.7 and autoconf-2.5x 
was difficult enough.

'include' shouldn't have a makefile.
'texinfo' is either imported from outside, or doesn't have a makefile.
'config' doesn't have one.
'contrib' shouldn't have one.
I'm not sure about 'etc', but I think it shouldn't.

I don't know anything about 'blt', but it's not built by the top level, 
so shouldn't be an issue.
'cgen' isn't built by the top level currently (although it will be again 
sometime in the future) so it's not an issue either.
'dejagnu' is imported from outside, so we shouldn't touch it.
'expect' is imported from outside.
I don't know about 'intl'.
'itcl' is imported from outside.  (I think it still is, anyway.)
I don't know about 'iwidgets', but it's not built by the top level, so I 
don't think we have to worry about it.
--> 'libgloss' actually needs to be done, I'm afraid.
--> I'm not sure about the status of 'libgui'.
--> 'newlib' actually needs to be done as well.
'readline' is imported from outside.
'tcl' is imported from outside.
'tk' is imported from outside.
--> 'winsup' is Cygwin.  It should be done, sometime.
--> 'sid' should be done.

> gcc:        libbanshee libchill libio libmudflap libstdc++"
'libbanshee' is branch only; the branch maintainer should do this.
'libchill' is dead.
'libio' is dead.
'libmudflap' is branch only; the branch maintainer should do this.
'libstdc++' is dead.

In other words, excellent work. :-)
I'll try to make a pass at the remaining directories, but I'm not sure 
when I'll get to them.

I'd like to see some version of this in sooner rather than later; 
incremental fixes are easier from this point than from the current 
point, and it would be nice if it went in during gcc 'stage 1' when 
major destabilizing changes are allowed.

 > autoconf:        2.57 (with the attached patch)
Think you can submit the patch to the autoconf maintainers and get it 
into mainline autoconf?

 >top-diffs.txt        Patches to top-level files in both 'src' and gcc.
Honestly, I've wanted to make the ${x_alias}-->${x} change for the 
directory names for a *long* time, but
a) it has to be done synchronously in all subdirectories and
b) it changes developer-visible behavior for cross builds (canonical 
name rather than specified name)

If I could get buy-in from gcc, gdb, and binutils for a patch doing just 
that, I would put it in right now (and make your diffs for autoconf 2.57 
conversion rather shorter).  I never submitted it 'cause I figured it 
would not be popular.

An alternative, if perhaps sillier, scheme would be to create new 
autoconf macros to find the ${build_subdir} and ${target_subdir} values, 
and put it in a file included by everyone who cares.

But it's *much* simpler to always use the canonicalized names.

Two general comments:

1) I notice that you made the existing pseudo-AC_PROG_CC/CXX macros
   work again with 2.5x; this is wrong.  Get rid of them entirely,
   use the canonical AC_PROG_CC/CXX, and if they don't work right,
   patch autoconf until they do.

2) Why did you disable the shared config.cache?  It speeds up 'make
   configure' by an order of magnitude, especially on slow machines.

The original theory was that I was trying to keep the diffs to a 
minimum, and that once the switch was flipped on 2.x, we could go back 
and make a lot of more interesting cleanups to the configure scripts.  
But I think you're right that my changes ended up complicated enough 
that I should just replace them with the modern versions; I'll do that.

I didn't disable the config.cache in the top-level scripts; it's just 
that the new default is for autoconf to use a null cache file unless 
configured with '-C'.  A good portion of my patch is actually present 
solely to fix the use of a top-level cache file --- there were a number 
of places where whitespace triggered the "value changed between runs" 
checks in 2.5x.  I did disable the target config.cache, because there 
were places where things really were being run with different flags 
between runs (for example, the value of libstdcxx_flags varies by 
directory), and fixing that seemed beyond the scope of the initial 
conversion to 2.5x.

That's fair...

It may actually make sense to do the replacement as a separate patch,
introducing a shared aclocal.m4 fragment that backports
AC_NO_EXECUTABLES or similar to 2.13.  Put that in first, and your
diffs for the 2.5x conversion get quite a bit simpler.

I may have misunderstood your patch but I got the definite impression
that you dropped out the only bit that passes down the top-level
--cache-file setting to the sub-configures.  Which would mean, even if
the top level was run with -C, the sub-configures would use no cache
file, and wouldn't share caches if they did.

The change of default is wrong, but that's not your fault.

Yeah, that's reasonable.  We'll want it back eventually though.
