I think we should we close this as WONTFIX. Or are these patches still useful?

WONTFIX (--enable-intermodule has been removed and is obsoleted by
--with-build-config=bootstrap-lto).

updated patch including unwind and eh and handling of static

includes untested draft for --disable-shared which contains:

# XXX: FIXME: for static libs vis_hide is forced off, so why does the normal
# build above have this superfluous occurence?
# Play safe and provide this wrong rule and retain the mention of vis_hide
# above.

updated patch for libgcc

Fixes an error about {mul,div}{d,x,t}c3 which wants to be built for different
modes / different types;

output is
/scratch/obj.i686/gcc-4.3/i686-linux-gnu/./libgfortran/.libs/libgfortr
an.so: undefined reference to `__divdc3'

We need to compile for each of the dc, xc, tc variants separately, due to
implementation details (macros). lib2funcs_{d,x,t}c variables and corresponding
pbjects are used for this.

Approximately 73% size-saving and 78% on-disk savings.

updated patch

tiny fix: libgcc-s-objects-onestep is only needed for enable_shared=yes.

Two other buglets fixed that were exposed by building libgcc with
--enable-intermodule, see second changelog below.

libgcc/ChangeLog:
2007-11-19  Bernhard Fischer  <>

        * configure.ac: Add option --enable-intermodule for onestep
        compile.
        * Makefile.in: Use onestep.

gcc/ChangeLog:
2007-11-19  Bernhard Fischer  <>

        * gbl-ctors.h: Add header guard.
        * libgcc2.c: Avoid redefinition of FUNC, use FUNCU for
        __floatundi?f
        * config/libbid/bid64_div.c: Extern decls of
        __bid_{convert_table,factors,packed_10000_zeros} have to be const.
        * libgcc/config/libbid/bid128_div.c: Likewise.

Scratch that. Testing a working version that i will attach when it passes the
check.
