I think the options are:
1) handle TRUTH_{AND,OR}IF_EXPR in expand_expr again (revert part of Paolo's
2004-08-09 expr.c dead code removals) - while these aren't present
in GIMPLE nor can be created by TER, they can be created by folding during
expansion. Maybe even COMPOUND_EXPR could be handled there and all the
ugly hacks builtins.c does to work around this could be removed.
2) have a special flag for fold-const.c, set during expansion, that would
preclude certain kinds of folding (e.g. creation of the trees that aren't
handled by the expander)
3) have expand's special versions of the various fold* routines, look for the
unhandled trees in what it creates and either fail to fold them, or
transform
to something else.
IMHO 1) would be probably easiest to implement, 3) too ugly to live, 2)
possible.

--- Comment #6 from mikpe at it dot uu dot se 2008-08-08 13:58 --- (In reply to comment #4) I can confirm that the reduced test case fails for me with gcc 4.0.4, 4.1.2, 4.2.4, and 4.3.1 on both powerpc and powerpc64. gcc-3.4.6 and older work. It doesn't fail for me with gcc-4.x on either sparc64 or arm. -- mikpe at it dot uu dot se changed: What|Removed |Added CC||mikpe at it dot uu dot se http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37014
