Hi,
I tried this combination in-tree:
gmp -> gmp-6.1.0
mpfr -> mpfr-3.1.3
mpc -> mpc-1.0.3
isl -> isl-1.15
While I can now reproduce the original problem,
I noticed another anomaly:

Does the latest GMP snapshot from https://gmplib.org/download/snapshot/ work
for you? I moved NO_ASM to config.h, so GCC's approach of overriding CFLAGS
should not break it anymore.

Ah, I managed to reproduce. GMP has a nice "CFLAGS= -g -DNO_ASM" in its
Makefile, but gcc overrides it by calling make CFLAGS=-g. Not much we can do
from the GMP side (and ISL is innocent). Well, maybe the def

you should use whatever gmp,mpfr,mpc version you like.

That should work, but dont expect it to work in-tree.
Instead use the --with-gmp --with-mpfr

OK, then it would make sense to have a documentation fix for GCC that specifies

It is on purpose that the in-tree gmp is configured to use no assembly,
but the in-tree configuration does not really work with gmp-6.1.0,
and apparently disables the assembly only half-way. It is not poss

On Native ARM platform the bootstrap does work with the old in tree GMP 4.3.2,

Bernd, I don't think there is any argument that those specific versions of the

The initial bug report was for cross compiling. Bug 70211 is for native builds
on ARM. Given the huge growth in ARM development boards, this needs at least
documenting. As with the original reporter I spent

GMP does, or did, select an ABI at configuration time that may not be the

Thanks for your swift comment!
I disagree that the bug is in ISL. The problem is that gmp, although the build
appears successful, is *not* correctly built. Six object files that should be
