Hello,

  I've obtained the patches for Ron Guilmettes (rfg@mcc.com) protoize
package for automatic prototype generation. This patches are based on
Rev 1.35 of gcc. I applied them with some trouble, as the 1.37 based
OSF files are quite distant from the 1.35 files, and got a running
version. Unfortunately I've also got some problems with that stuff:

a) when using -fgen-prototypes together with -fsyntax-only, I get
   core dumps from cc1. -fgen-prototypes modifies the tree structure
   in one place. When I uncomment that stuff (which came with the
   protoize patch), the core dump disappears. The offending code
   came with this piece of patch:

***************
*** 875,883 ****

        /* If declaring a type as a typedef, and the type has no known
!        typedef name, install this TYPE_DECL as its typedef name.  */
        if (TREE_CODE (x) == TYPE_DECL)
        if (TYPE_NAME (TREE_TYPE (x)) == 0)
          TYPE_NAME (TREE_TYPE (x)) = x;

        /* Multiple external decls of the same identifier ought to match.  */

--- 879,907 ----

        /* If declaring a type as a typedef, and the type has no known
!        typedef name, install this TYPE_DECL node as its typedef name.
!
!        If we are generating prototypes, and if the type being created in
!        this typedef statement already has a name, we still have to preserve
!        the information which associates the new (typedef'ed) name with the
!        given type specification so that prototypes can be generated which will
!        use names declared in typedef statements (as appropriate).  In these
!        (rare) cases where another name for the same type already exists, we
!        clone the node which represents the type specification and make the
!        clone's DECL_NAME equal to the (new) typedef name.  */
!
        if (TREE_CODE (x) == TYPE_DECL)
        if (TYPE_NAME (TREE_TYPE (x)) == 0)
          TYPE_NAME (TREE_TYPE (x)) = x;
+       else
+         if (flag_gen_prototypes)
+           {
+             tree copy = copy_node (TREE_TYPE (x));

+             if (TYPE_MAIN_VARIANT (TREE_TYPE (x)) = TREE_TYPE (x))
+               TYPE_MAIN_VARIANT (copy) = copy;
+             TREE_TYPE (x) = copy;
+             TYPE_NAME (copy) = x;
+           }
+
        /* Multiple external decls of the same identifier ought to match.  */

2) Suppose I have the following code:


typedef char *bla;

sbr_xxx(xxx)
char *xxx;
{}

  In that case the genrated .p files says that the prototype for
sbr_xxx is 'int sbr_xxx(bla xxx)', which in my oppinion is not the
desired effect. If you are converting c-files and all your 'char *'
variables went into 'va_list's, because in some include-file va_list
is defined as 'char *', the result is rather confusing (even if the
code works perfect). The solution would be to change some code in
proto-gen.c, but I don't know where to look.

  My questions are:

- are these problems already known?
- is there a newer version of protoize ou in netland that fits better
  to gcc-1.37.
- any advise from some kind soul?
