will fix it.  If someone can confirm that would be great.

Re: we are starting the wide int merge

[Christophe Lyon]

I have noticed build failures too (arm, aarch64).

It also looks like the git-svn-id property is now wrong/incomplete.
For instance, commit 9a5942c1d4d9116ab74b0741cfe3894a89fd17fb has:
    git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/branches/wide-int@201706
138bc75d-0d04-0410-961f-82ee72b054a4

How does it map to the SVN commit in trunk?

Thanks,

Christophe.

I tried that on my p7 and on my x86_64 machines, they both build fine.

This is a commit on the wide-int branch (the one that created it).

Looks like this is specific to 32-bit HOST_WIDE_INTs.  The problem was
that loop-iv.c was using HOST_WIDEST_INT and no template specialisations
were defined for that.

Richard B's patch to force HOST_WIDE_INT to 64 bits will fix this.

That isn't actually fallout from the wide-int merge, but of later
added code.

Other targets affected are moxie-elf, aarch64_be-elf, alpha-linux,
cr16-elf, ppc-linux, hppa-linux, arc-elf, younameit.

Is anybody able to reproduce this, for example on a GNU/Linux system?

This tester of mine hasn't been able to bootstrap for nearly a week,
and timing-wise it would be really a coincidence were this not due to
wide-int.

i386-linux-gnu won't bootstrap for me because there are no out-of-line
definitions of the sync_* routines.  I think this is expected.
i486-linux-gnu seems to bootstrap fine.

To rule out one possibility: which GCC are you using for stage1?

I think that may the smoking gun.  When I use GCC 4.7 to bootstrap,
FreeBSD 8, 9 and 10 all build fine on i386 (= i486) and amd64.

When I use the system compiler, which is GCC 4.2 on FreeBSD 8 and 9

This means this clang-based system is not able to bootstrap GCC trunk
on amd64.

Perhaps looking into this first may affect the failure on i486?

Do you get exactly the same comparison failures using clang and GCC 4.2
as the stage1 compiler?  That would rule out the system compiler
miscompiling stage1.

This is PR 61146.  You can get around it by adding -fheinous-gnu-extensions
to BOOT_CFLAGS.

'Fraid it won't help.  We don't use umul_ppmm (or even include
longlong.h) for 486.

I couldn't reproduce this with GCC 4.2 but I could with clang.
The problem is that the C++ frontend's template instantation code has
several instances of foo (..., bar (...), bar (...), ...), where bar (...)
can create new decls.  The numbering of the decls can then depend on which
order the compiler chooses to evaluate the function arguments.  This later
causes code differences if the decl uids are used as tie-breakers to get
a stable sort.

I was just unlucky that this happened to trigger for the new wi:: code. :-)

I'm testing a patch now.  It might need more than one iteration, but hopefully
I'll have something to submit tomorrow.

Thanks,
Richard
