It would be nice if these were either fixed, or ada was disabled per default on

I'd attach the requisite testcase, but that seems like half of the entire ada 
compiler... I can though, if it's deemed necessary.

Please include these source files with error report
Note that list may not be accurate in some cases,
so please double check that the problem can still
be reproduced with the set of files listed.

PLACEHOLDER_EXPR is gimple so it should be handled in walk_tree on the tree-ssa 
branch but it is not.  This is still a P1 because it most likely also is busted on all targets.

Okay I just looked into the sources for walk_tree and since PLACEHOLDER_EXPR is 
defined in tree.def in the gcc, that makes it gimple, walk_tree should know how to handle 
it, this is a bug.  Changing to middle-end because walk_tree is considered the middle-
end.  This is also target independent.

[  Jason, added you to CC: since you're the "GIMPLE man"...
   Please correct me if I am wrong somewhere :-)  ]

Andrew,

You say in the audit log that PLACEHOLDER_EXPR is GIMPLE, but you seem to miss
an important point: GIMPLE is not the same as the set of tree nodes defined in
tree.def.  Your remark that "since PLACEHOLDER_EXPR is defined in tree.def in
the gcc, that makes it gimple" is simply not true.

In fact, PLACEHOLDER_EXPR is used in exactly one front end (Ada) and the only
reason why it is in tree.def is because the Ada front end apparently was allowed
in the past to clutter the language independent tree code set with language
specific ones.  As far as I can tell, PLACEHOLDER_EXPRs are necessary in Ada
because they represent information about information that is not available at
the time when Ada expands its native AST to RTL.

Once Ada starts producing functions as trees, it should be perfectly feasible
for them to eliminate PLACEHOLDER_EXPRs in an extra pass before expanding (in
fact, they will have to since the GIMPLE tree would have to represent the full
semantics of the Ada program unit).  At that point the PLACEHOLDER_EXPR
definition should be moved out of tree.def and into ada/ada-tree.def

That was the PLACEHOLDER_EXPR discusion....



Now about the actual problem here:  Why would Ada end up using walk_tree() in
the first place?

The function walk_tree() is intentended to be used by front ends which produce
functions at trees, or at least partially complete trees.  Ada does neither,
instead it produces its own AST and expands to RTL from there directly,
bypassing the functions-as-trees infrastructure.  Therefore, the real problem is
that Ada somehow ends up using walk_tree() when it should not.  Unfortunately
there is no GDB backtrace in the audit log of this bug, so it's hard to tell
where things go awry.

Dara, could you distill a smaller test case from the problem?  Maybe there's
some kind of Ada preprocessor that can collect the relevant information from all
those modules???

I am trying to build Ada now for the first time (never had the appropriate GNAT
until last week when I installed RH9), and if there's a test case we can hunt
this problem down more easily.

Gr.

OK I have a trace for this one.  The problem seems to be that the default lang
hook.  Jason, it turns out to be a patch of yours:

2003-01-02  Jason Merrill  <jason@redhat.com>
                                                                               
                                 
        * c-simplify.c (c_genericize): Dump more info about the function.
        Use dump_function.
        * tree-dump.c (dump_function): Move from cp/optimize.c.
        * tree-dump.h: Declare it.
                                                                               
                                 
        * gimplify.c (mostly_copy_tree_r): Remove unnecessary cases.
        (unshare_expr): New fn.
        * tree-inline.c (mark_local_for_remap_r, unsave_r): New fns, adapted
        from C++ versions.
        (lhd_unsave_expr_now): Likewise.
        * tree.c (unsave_expr_now): Remove.
        (unsafe_for_reeval): Labels and BIND_EXPRs are only somewhat unsafe.

The problem is that tree-inline.c:lhd_unsave_expr_now uses
walk_tree_without_duplicates.

Jason, can you fix this, I don't understand what you tried to do here with this
change, and I can't find a message for it in the mailing list archives...
