Changeing BIGGEST_ALIGNMENT changes the ABI.

I was able to build a cross gcc with the patch below.
But I do not know if this correct. Especially I do not know if we can lower the
BIGGEST_ALIGNMENT. If not, I do not know how to

The last build was successful with commenting BIGGEST_ALIGNMENT and adding
PREFERRED_STACK_BOUNDARY 32.
I'll continue later.
Thanks Andreas!

Also BIGGEST_ALIGNMENT is bigger than (PREFERRED_)STACK_BOUNDARY.

The real problem appears to be that netbsd-elf redefines STACK_BOUNDARY to 32,
but leaves PREFERRED_STACK_BOUNDARY at the default 16.

Unfortunately the issue is not solved yet. I was informed that 68010 needs
STRICT_ALIGNMENT. So I have to think about how to solve this.
Afaik, netbsd has 68010 machines (Sun?).

If there are any bug'etiquette steps I am supposed to perform, please tell me
(i.e. I have to close/resolve it since I opened it).

Thanks!!!
This worked. I never thought to try a Linux build. Live and learn.
I guess it is a good thing I'm not a gamblin' man.

I tried to do a build with svn release and it failed for me. Same problem.
xgcc says it is 4.3.0.

This was my fault. I have in mind that my breakage happened between 4.2 and
4.3. (And you write that 4.2.4 is ok, right?)

I'll do the 'svn thing'. But I am not an experienced svn user so it may take

The result of -dr for fixunsxfdi() for 4.2.4 is 648 lines. Only 80 are produced
by 4.3.5. It appears to die on the left shift.
