This is a rather worrying regression:
Andrew, does this ring any bells?

------- Comment #3 from paul dot richard dot thomas at cea dot fr 2006-08-08 14:15 -------
(In reply to comment #2)
> I wonder if this was caused by Jakub's patches for openmp.
Or Richard Sandiford's patches. The above produces:
gee ()
{
int4 .s;
__builtin_memmove (&(*(char[0:][1:3] *) m.data)[NON_LVALUE_EXPR
<m.dim[0].stri
de> + m.offset], s, 3);
}
bar (s, n, _s)
{
struct array1_unknown m;
bit_size_type D.914;
<unnamed type> D.915;
static void gee (void);
.s = *n;
D.914 = (bit_size_type) (<unnamed type>) .s * 8;
D.915 = (<unnamed type>) .s;
m.data = 0B;
}
so that .s is declared in gee but used in bar.
This:
subroutine bar(s, n)
integer n
character s*(*)
character*3, dimension(:), pointer :: m
contains
subroutine gee
m(1) = s(1:3)
end subroutine gee
end subroutine bar
compiles correctly and outputs this code:
gee ()
{
__builtin_memmove (&(*(char[0:][1:3] *) m.data)[NON_LVALUE_EXPR
<m.dim[0].stri
de> + m.offset], s, 3);
bar (s, n, _s)
{
struct array1_unknown m;
bit_size_type D.913;
<unnamed type> D.914;
static void gee (void);
D.913 = (bit_size_type) (<unnamed type>) _s * 8;
D.914 = (<unnamed type>) _s;
m.data = 0B;
}
where _s is used directly.
The declaration for .s needs to be boosted to the correct context.

It was caused by the openmp changes, but guess usually the parent routine
at least touches the dummy argument and therefore it would be added to the
right context.
I was testing:
--- trans-decl.c.jj 2006-08-09 15:39:36.000000000 +0200
+++ trans-decl.c 2006-08-09 15:44:35.000000000 +0200
@@ -884,7 +884,10 @@ gfc_get_symbol_decl (gfc_symbol * sym)
if (TREE_CODE (length) == VAR_DECL
&& DECL_CONTEXT (length) == NULL_TREE)
{
- gfc_add_decl_to_function (length);
+ if (sym->ns->proc_name->backend_decl == current_function_decl)
+ gfc_add_decl_to_function (length);
+ else
+ gfc_add_decl_to_parent_function (length);
gfc_defer_symbol_init (sym);
}
}
before I saw Paul's patch on gcc-patches, guess both versions will DTRT.

Go with your version, you posted first ;).
I added the comment just to support your patch, that I independently came
to a (almost) same fix.
