Hi Gerald and friends
(what follows is a copy of a message sent earlier today to Gerald)
At http://www.gnu.org/software/gcc/extensions.html we have a reference
to the DLX port of GCC, which corresponds to the DLX machine described
in Computer Architecture: A Quantitative Approach by Hennessy

Over the previous years, I had downloaded and used both a really archaic
gcc-1.09 DLX backend as well as the one you refer too. They are both in a sad
state of affairs, but the gcc-2.7.2.1 (AFAICR) was usable.
Offtopic: if you still have such an old gcc-1.09 (?)
Offtopic: if you still have such an old gcc-1.09 (?) release around, please

Oops, reality check :)
My glibc version for DLX is 1.09. The GCC version seems to be either 1.37.1 or
more probably 1.39.

I think this is related to PR 34472 and PR 34534
true.
Would you please see the comment #4 for PR 34534, and try it on your machine?
Thank you,

(*) This is actually running on i686-pc-linux-gnu, in a chroot which (with the
help of Wine) masquerades as i686-pc-mingw32 so most packages can be compiled
natively (cross support in general is weak, cross support to w32 even
weaker).

Hmm. Looking at PR 29826, this is indeed the same bug; maybe a different
version of the mingw headers? And I wonder why I didn't find it when I searched
for it ...

So I wonder whether this test works correctly even without -fipa-struct-reorg.
Would you please try to compile it with all other options (-O3 -fdump-ipa-all
-fwhole-program -combine
