Jan, this bug is now open for two weeks with no indication of any
progress. It breaks Ada bootstrap on a primary platform, so please fix
or revert your patch.

Hi,
the contant folding in tree-ssa-ccp has several bugs in it concerning to arrays
with non-0 low bounds. This happens in Ada and fortran and since fortran
produces array constructors that the code confuses in a way that we don't fold
most of time, Ada is probably only one affected.
I rewrote the code but the patch took a while to settle since it is quite
touchy area. I am just doing final testing and will commit it shortly.
Hopefully it will fix both the problems. If not, we need to figure out what
Ada does special about static constructors - this would seem more like a
frontend bug.

I think I will just commit it as the patch fixes known problems anyway and let
you know then. If it won't help in this case, it is not difficult to make
patch to dump folding that happens with initializers that mis the TREE_STATIC
bit and we can figure out if the problem is caused by Ada frontend putting
something weird into the constructor.
There was related problem with C++ vtable constructors having references to
static
variables from other compilation unit, so it is quite posible that it is
FE<->BE
interface issue, too.
I wonder if it is possible to get this into self contained testcase - I will
try to
reproduce problem at compile farm, I think it has sparc machine there.

Fine, thanks. Let me know if you need Solaris/SPARC testing before
commit.

Jan, this is the second of your recent patches (after PR bootstrap/45612) to
break Ada/SPARC bootstrap. Could you please have a look?
Thanks.
Rainer

Subject: Re: New: [4.6 regression] Comparison failure in gcc/ada/ali.o on
Solaris 2/SPARC
A reghunt identified the responsible patch:
2010-09-10 Jan Hubicka <jh@suse.cz>
* tree-ssa-ccp.c (fold_const_aggregate_ref): Do not check STATIC flag.
Reghunting was a nightmare in this case since there was lots of
intermediate breakage which left the tree unbuildable for unrelated
reasons.
