Well, the workaround removes the ICE, but constructor handling
appears still broken:

Mark,

> case.
Well, this is definitely not Ada-specific, see comment #11. According to your
analysis for PR c++/23171, the middle-end has started rejecting constructs it
used to accept, lightly breaking the C++ compiler and severely breaking the Ada
compiler in the process. What should we do for 4.1?

------- Comment #28 from uweigand at gcc dot gnu dot org 2005-11-15 18:31 -------
Just one additional comment: the patch from comment #10 was rejected,
maybe because it required changes to the core gimplifier.
However, I've tested just the Ada front-end pieces from that patch,
and this *already* fixed the problem for me. The reason appears to
be that -in general- occurrences of ADDR_EXPR (CONSTRUCTOR) do not
constitute a problem.
The problem only comes when such constructs occur in turn as part of
another (outer) CONSTRUCTOR. The middle-end never generates that case,
only the Ada front-end does -- thus it suffices to fix those cases in
the Ada front-end itself.
So I guess it would be possible right now to fix the bootstrap issue
by a pure front-end patch. (This doesn't address the more general
question of whether or not the gimplifier has a bug that can be exposed
by other front-ends too, of course ...)

OK, thanks for the analysis.
Richard, what do you think? The pure front-end patch Ulrich is talking about
is the Ada FE part of http://gcc.gnu.org/ml/gcc-patches/2005-07/msg01666.html

------- Comment #30 from uweigand at gcc dot gnu dot org 2005-11-17 01:08 -------
With that patch applied, Ada bootstraps on s390-ibm-linux and
s390x-ibm-linux. Regression test results are at:
http://gcc.gnu.org/ml/gcc-testresults/2005-11/msg00831.html
http://gcc.gnu.org/ml/gcc-testresults/2005-11/msg00832.html
There's still quite a number of regressions, but the good news
is that all of them are already known from other platforms.
Sorted by PR number, the regressions are:
both s390 and s390x:
PR 18659: c32001e c64105b c95086b
PR 22333: c34007p c34007r c45282b
PR 20548: c52103x c52104x c52104y
PR 22561: ca11c01
s390x only:
PR 18819: cdd2a01(*) cdd2a02
s390 only:
PR 20753: ce3810b
(*) The PR mentions only cdd2a02. But cdd2a01 fails with seemingly
the same symptom for me ...

Probably not the correct long-term fix. Might be good enough for 4.1 though.

Not very constructive, I'm afraid. Care to devise a fix?

this fix doesn't help for current 4.1.
workaround from #c23 doesn;t help either.

sorry, i don't known too much about compiler's infrastructure.
i'm just a software developer and packager.
i can test builds/fixes and provide backtraces on PPC970FX
but nothing more...

It works (or worked) on s390 at least and fix the first problem on PPC though.
Did you try to compile make.adb at -O1 or -O0?

i always do a full bootstrap with different flags for stage1 and 2+.
make bootstrap \
BOOT_CFLAGS="%{rpmcflags}" \
STAGE1_CFLAGS="%{rpmcflags} -O0" \
stage1 (with -O0) builds, stage2 fails.
(rpmcflags == -O2 + additional options).

That doesn't cover the Ada tools. They build for me at -O0 on PowerPC so with
Andrew's FE patch + a possible tweak in the Makefile, you should have an Ada
compiler.

it builds on ix86 with -march=i486, (i586 not tested) and i686
but fails in the same way on ix86/-march=athlon and amd64/-march=x86-64.
maybe this failure is related to some lowlevel amd-specific parts?
