I picked a name.

Here is a new patch for gcc.
I still haven't updated the src side, but there's little to do there
that isn't already done in this patch.

Ok?

Tom

Tom> Ping.

This is the third ping.

Please review the patch.

There are two choices:

1. Approve the original patch, adding a file to libiberty.
   Given how much code in libiberty is already unrelated to portability,
   I would say this is the simplest route.
   From a quick glance -- concat.c, the demangler, crc32.c,
   dyn-string.c, fdmatch.c, fibheap.c, hashtab.c, hex.c, md5.c,
   objalloc.c, obstack.c, sha1.c, simple-object*.

2. Approve the new patch adding libksink.

thanks,
Tom

Yeah, that would be my preference.  libiberty is already a kitchen sink,
has been handled that way for many years, and creating a new kitchen sink
library is both overkill and will not make it a kitchen sink if only
this dwarf strings stuff is added to that and all the other kitchen sink
stuff stays in libiberty.

DJ Delorie - April 26, 2012, 5:52 p.m.
I will not oppose adding more unrelated stuff to libiberty, but
neither will I approve it.  I will let one of the other maintainers or
a global maintainer approve it.

The original libiberty patch is ok for trunk then.

Thanks, Jakub.  I am checking it in to the gcc tree.
I'll send the gdb and binutils follow-ups later.

This breaks GCC bootstrap:

You should add extern "C" for C++ on those functions moved to
libiberty.

Yeah, sorry about that.
I'm testing the fix.

+/* This file declares various DWARF-related constants using a set of
+   macros which can be redefined by the including file.
+   
+   The macros are in sections.  Each section corresponds to a single
+   set of DWARF constants and has a corresponding key.  The key is
+   used in all the macro names.
+   
+   The sections are TAG (for DW_TAG_ constants), FORM (DW_FORM_), AT
+   (DW_AT_), OP (DW_OP_), ATE (DW_ATE_), and CFA (DW_CFA_).
+   
+   Using TAG as an example, the following macros may be used for each
+   key:
+   
+   DW_FIRST_TAG(name, value) - Introduce the first DW_TAG constant.
+   
+   DW_TAG(name, value) - Define a subsequent constant.
+   
+   DW_TAG_DUP(name, value) - Define a subsequent constant whose value
+   is a duplicate of some other constant.  Not all keys use the _DUP
+   macro form.  If more than one name shares a value, then the base
+   (DW_TAG) form will be the preferred name and DW_TAG_DUP will hold
+   any alternate names.
+   
+   DW_END_TAG - Invoked at the end of the DW_TAG constants.  */
