Hmm, are you sure you bisected that correctly? I did a build on gcc60 with the
patch reverted, and it failed with the same error.

It's indeed a very unlikely candidate (unless cc1[plus] is miscompiled of
course).

The miscompiled function seems to be evaluate_stmt or possibly the
functions it is inlined to because the transformation happens in early
SRA.
Nevertheless, when we revert to the old behavior (enum type scalar
replacements) when creating a replacement for val.lattice_val in this
function the bootstrap finishes.

--- Comment #7 from Martin Jambor <jamborm at gcc dot gnu.org> 2011-09-19 18:21:25 UTC ---
The compilation before and after the patch seems to diverge at expand
time and only in one instruction when processing this particular
gimple statement:
MEM[(struct prop_value_d *)&D.39146].lattice_val = val$lattice_val_443;
When val$lattice_val is an enum type, it is expanded to:
(insn 4927 4926 4928 593 (set (mem/s/c:SI (reg/f:DI 2698) [10 MEM[(struct
prop_value_d *)&D.39146].lattice_val+0 S4 A128])
(reg:SI 433 [ val$lattice_val ]))
/abuild/mjambor/trunk/src/gcc/tree-ssa-ccp.c:1685 -1
(nil))
whereas when it is <unnamed-unsigned:32>, it is expanded to:
(insn 4927 4926 4928 593 (set (mem/s/c:SI (reg/f:DI 2698) [4 MEM[(struct
prop_value_d *)&D.39146].lattice_val+0 S4 A128])
(reg:SI 433 [ val$lattice_val ]))
/abuild/mjambor/trunk/src/gcc/tree-ssa-ccp.c:1685 -1
(nil))
The difference is 4 instead of 10. Now I am entering an entirely
unchartered territory for me on quite a few levels so don't hold your
breath for any progress. I will keep looking into this, though.

The different alias set (4 instead of 10) is then just carried along
in the RTL dumps not causing any different behavior until

The bad commit listed in comment #4 was back ported to the 4.6 branch so the
check in from comment #9 should be ported over to the 4.6 branch as well. I am
reopening the bug for that reason.

The "bad" PR49911 commit was backported to 4.5 branch too, in r178701. I
haven't checked yet if it caused any regressions there or not.

The 4.5 branch doesn't have build_ref_for_model and the only call to build3 on
a COMPONENT_REF already uses the type of the field, so it shouldn't be
affected.
