It seems this is related to order of cgraph_optimize() and writing globals. If globals are wrapped up 
before emitting code then debug info. is not emitted for uninitialized globals, because DECL_RTL is not 
set. C++ FE writes globals before doing cgraph_optimize(), but C FE optimizes first. This is why this is 
C specific only. This patch fixes this but it causes varpool-1.c test failure. With this patch, GDB know 
about foo as well as bar when DWARF is used.

Actually the PR 21828 was orginally about stabs and not about dwarf-2:
"When using gdb-309 and gdb-370 on MacOS X 10.3.9, even the simplest queries seem broken." so 
really PR 21828 should never been closed until the stabs problem was fixed.

Then the test case in the PR (which you provided) should not have used 
DWARF-2.  I rely on the bugmasters to reduce bugs -- and they do a great 
job.

In any case, the problem is now either in the C front end or in the DBX 
generator.  Since the DWARF-2 generators do something reasonable, 
AFAICT, I would guess the problem is in either the DBX generator, or the 
  GDB reader for STABS, or in the STABS format itself.

This does not look like STABS or DWARF-2 specific. Right now it
does work even in DWARF-2 mode also. With the attached patch it DWARF-2
also works.

The DWARF-2 information looks correct to me, from the section of DWARF-2 code
that you posted in the original report for this bug.  I know GDB doesn't print
the variable, but I don't think that's the compiler's fault; the information
looks OK.  Is there something wrong with the DWARF-2 generated, or is this just
a GDB bug?

I'm not oppposed to making the kind of change you're proposing for the C front
end; I suggested the same thing.  But, it is a complex change; as you've noted,
there are regressions when you try it.

Without the patch, GCC does not emit DW_OP_addr and DW_AT_location.

There is only one regression. One way to avoid it is to split  
wrapup_global...
in two halves. One to emit code and second to generate debug info.  
This allows
C front end to put cgraph_optimize() after writing globals but before
generating debug info.

thoughts ?

Yes -- but that's no excuse for GDB not being able to show us the type!

It sounds sensible enough, but I really haven't studied how the C front 
end does things well enough to know for sure.  I would ask Joseph and RTH.

A more severe example is gdb.base/call-ar-st.c wherein the local static variable
"double_array" is not put to the debug info at all.  Not even its name as in the
example here.
