Confirmed, a regression from 4.1.2.

Janis,
  Could you do a regression hunt on this bug?

Thanks,
Andrew

------- Comment #3 from rguenth at gcc dot gnu dot org  2006-10-16 13:37 -------
Happens during inlining, so I guess one of the strip-useless-type-conversion
patches caused this.

But initialize_inlined_parameters shouldn't call into the frontend again here:

      /* Find the initializer.  */
      value = lang_hooks.tree_inlining.convert_parm_for_inlining
              (p, a ? TREE_VALUE (a) : NULL_TREE, fn, argnum);

I don't see why this should be necessary anymore as we're now inlining gimple?

Doesn't work out.  It looks like we depend on its side-effects in some
testcases:

FAIL: gcc.dg/assign-warn-3.c  (test for warnings, line 9)
FAIL: gcc.dg/assign-warn-3.c  (test for warnings, line 13)
FAIL: gcc.dg/pr29254.c  (test for warnings, line )
FAIL: gcc.dg/pr29254.c  (test for warnings, line 21)
FAIL: gcc.dg/warn-1.c  (test for warnings, line 15)
FAIL: gcc.dg/noncompile/pr16876.c (internal compiler error)
FAIL: gcc.dg/noncompile/pr16876.c  (test for errors, line 10)
...

pr29254 is artificial - it tests for the bogus warning, otherwise the warning
should be done in the frontend.

When I modify the testcase to have the function defintion after the use:

struct block;

static int remove_out_of_scope_renamings ();

int
ada_lookup_symbol_list (const struct block *block0)
{
  return remove_out_of_scope_renamings ((struct block *) block0);
}

static int
remove_out_of_scope_renamings (current_block)
  struct block *current_block;
{
  return 1;
}

I still see that the cast has been stripped at the point where
c_convert_parm_for_inlining is called:

(gdb) call debug_tree(value)
 <parm_decl 0xb593c000 block0
    type <pointer_type 0xb59315c0
        type <record_type 0xb5931564 block readonly VOID
...

OTOH, if I further change the passed parameter to a plain 0, value contains an
unadorned integer constant.   

(gdb) call debug_tree(value)
 <integer_cst 0xb58aa978 type <integer_type 0xb58bb284 int> constant invariant
0>

I think it is wrong that we are optimizing the expression before converting
it to the required type.
Moreover, why is it right to drop NOP_EXPRESSIONS there?  If for some reason
the compiler finds it needs to put the initializer in a temporary variable,
and uses the type of the value for that variable, we'll get an alias set
problem.

Hmm, This is one of the language hooks which really need to go away
for LTO as I understand it.  Also I the real problem comes from the
inliner or the gimplifier (I am betting the gimplifier) removing the
cast as it is useless in our type system.

How is LTO supposed to handle argument passing for inlining?  As I see it,
we have basically two choices:
1.: We pass a actual parameter with a type and a value of that type,
    to a formal parameter of a possibly different type.
    This can require conversions, which would have to be either done by
    frontend hooks (this is the way the intra-module inlining works at
    the moment), or by some frontend-independent mechanism that the
    frontends anticipate when they generate the parameter encodings for the
    call site.
2.: We pass an actual parameter as bit pattern in registers and/or a stack
    slot.  The inliner will have to figure out where its formal parameter
    is coming in, and will need to re-build abstractions that the optimizers
    can work with.

So you don't intend to fix this for 4.2?  I guess the patch you commited to
trunk
is too big for 4.2 but do you think there's some kind of workaround that could
be applied to 4.2?  This bug is quite annoying.

Does this means it'll get fixed by 4.2.3, or the 4.2.x series will stay bugged

Just means the current *intent* is to fix by 4.2.3 (or target milestone). 
A nudge might encourage someone to do it sooner on the 4.2 branch before 
the next release (since 4.2.2 was just out recently).

... but the audit trail suggests otherwise.  :S

Mark does not actually read the full list of messages when changing the target
milestone. I think this should be closed as WONTFIX since there is no easy way
to fix this for 4.2 but it is fixed in 4.3. As a workaround, you should be able
to use -Wno-cast-qual to avoid the warning. 

I don't remember if 4.2 supports -Wno-error=cast-qual. If it does, you can
still get the warning as a warning even when using -Werror.

It does, thanks for the tip. I added this to my makefile:

check_gcc = $(shell if $(CC) $(1) -S -o /dev/null -xc /dev/null > /dev/null
2>&1; then echo "$(1)"; else echo "$(2)"; fi ;)
# Work-around for stupid gcc 4.2 bug
ifneq ($(findstring Werror,$(WARN)),)
        WARN += $(call check_gcc,-Wno-error=cast-qual,)
endif

... now it compiles fine with -Werror both on gcc 4.1 and 4.2.

It would be nice if this bug would get somehow documented on gcc manual or the
main site before gcc 4.2.3 release.

I agree. But I am not sure how this is typically done (I am too newbie). I
think if you write a patch [*] for http://gcc.gnu.org/gcc-4.2/changes.html (a
new item under Caveats) pointing to http://gcc.gnu.org/PR29478 with you would
like (as an user) to know, that may do. Send it to gcc-patches@gcc.gnu.org

If you have any doubts, ask me. Thanks.
