[Bug bootstrap/43941] New: Impossible to build any version beyond 4.2.4

[Bug bootstrap/43941] New: Impossible to build any version beyond 4.2.4

[h dot m dot brand at xs4all dot nl]

Managed to build gmp-5.0.1, mpfr-2.4.2, and mpc-0.8.1 with gcc-4.2.4/64 (all
-mlp64). Had to set $ABI to 64 to make that pass.

Due to the endless annoying libtool, building with HP C-ANSI-C was impossible.

With that triplet installed, and hand-forced iconv to be unavailable
(--disable-nls does not disable it's use and configure seems to think it is
there where it is not), I had to handcompile version.c because of quotation
errors.
Those are all things I can work around, but here it stops:

It's your own source, so I don't think I have to include it.

(Even HP's porting center gave up after gcc-4.2.3)

You have at least to state how exactly you configured the compiler.  Please
also specify what host compiler you used.

I've built GCC on IA64 HP-UX 11.31, but never in 64 bit mode.  I build in 32
bit mode (the default for GCC and HP C) and I haven't seen this problem.  I'll
try
building in 64 bit mode to see if I can reproduce the problem but it may take a
while since all the libraries in my BE (gmp, mpfr, etc) are in 32 bit mode and
I'll need to create 64 bit ones.

I haven't tried building GCC with the HP compiler in some time.

I have reproduced this failure, and the problem seems to be in GMP.  You
mention that you set ABI to 64.  I noticed that if I built GMP with the HP
compiler ABI is set to 32 and then when I built GCC with that GMP it failed in
the manner you show in your report.  When I built GMP with GCC, ABI was set to
64 and the compiler I built with that GMP worked fine.  You might want to try
rebuilding GMP with GCC.

Also, you mentioned that the HP Porting Center only has GCC 4.2.3, you can get
newer pre-built GCC versions for HP-UX at http://www.hp.com/go/gcc (though
these are all built in 32 bit mode).

I was able to build GCC using HP C (in 32 bit mode) with no problems and no
changes needed.

I have just rebuilt gmp, mpfr, and mpc with GNU gcc-4.2.4/64 ABI=64

All checks passed for gmp, mpfr, and mpc before I installed

Using the below Conf:
--8<---
export LD_PXDB=/usr/bin/true

export CONFIG_SITE=
export CC=gcc
export CFLAGS="-mlp64 -fPIC"
export CCFLAGS="-mlp64 -fPIC"
export CXXFLAGS="-mlp64 -fPIC"
export PATH=/pro/3gl/GNU/gcc/bin:.:/usr/local/ia64/bin:/pro/local/bin
export PATH=$PATH"":/usr/bin:/opt/ansic/bin:/usr/ccs/bin:/opt/langtools/bin
export PATH=$PATH"":/opt/imake/bin

rm -rf obj
mkdir obj
cd obj
../src/configure \
    --enable-languages=c,c++ \

    --with-ld=/usr/ccs/bin/ld \
    --disable-shared \
    --disable-nls \
    --with-mpfr=/usr/local/ia64 \
    --with-gmp=/usr/local/ia64 \
    --with-mpc=/usr/local/ia64
# Force 64bit in STAGE1_CFLAGS
perl -pi -e'm/CFLAGS\s*=/ and s/-fkeep-inline-functions/-mlp64
-fkeep-inline-functions/' Makefile
-->8---

Building gcc failed with an internal compiler error for 4.3.4, 4.4.4,
and 4.5.0 (all at a different location btw)

I need a 64bit environment, because I have only 64bit libraries and
need a 64bit libgcc to link with other applications.

I have binutils-2.18 available, for which I had to disable ar and ranlib

------- Comment #6 from sje at cup dot hp dot com  2010-07-29 21:50 -------
Because the ia64-hp-hpux11.31 compiler generates 32 bit code by default you
cannot do a bootstrap build in 64 bit mode.  From install.texi:

Note that the bootstrap compiler and the resulting GCC must be link
compatible, else the bootstrap will fail with linker errors about
incompatible object file formats.

Since the resulting GCC generates 32 bit code and the bootstrap compiler you
are using generates 64 bit code they are not link compatible.

Note that you can build GCC in 32 bit mode and still use the resulting compiler
to compile programs in 64 bit mode by using the -mlp64 option.
