Updated patch: http://gcc.gnu.org/ml/gcc-patches/2009-09/msg01477.html
You used a too simple testcase which doesn't need any of the DWARF4 additions.
Use a more complicated one, e.g. try the gcc.dg/guality/ testcases with
-g{,no-}strict-dwarf.

well that's true - but I'd stopped there since even that simplistic case was
giving errors with
dwarfdump --debug-frame
once we figure out how to get bootstrap working again .. I'll do the

Changed the subject to reflect the comments.
[this might not be quite enough; backing out of only 151814-151815 for trunk

fails].

Perhaps this gives us a starting point for producing a test-case that (a) fails on darwin toolset and (b) is demonstrably correct by some other means -- i.e. bug is squarely in the toolset. these particular tools are not currently open sourced - and therefore it is impossible for us to require them to be fixed on any particular version of darwin (if they were open I'd gladly volunteer to attempt the fix myself). To that end I have enquired on darwin-dev as to the likelihood of them being open-sourced. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41405

For what I understand (very little) it mostly reverts revision 151815 by replacing the removed 'dwarf_version = 4' by '(dwarf_version = 4 || !dwarf_strict)'. So I still don't understand why revision 151815 is not reverted NOW in order to allow darwin to bootstrap with trunk. Then there will be plenty of time to apply your patch after it has been discussed by competent people. It would also be of interest to document in PLAIN English why it is so important to include dwarf4 stuff for systems that do not support it.

I believe I've caught all DW_OP_{implicit,stack}_value uses in dwarf2out.c, so
likely -gstrict-dwarf wasn't used when compiling something that has been linked
into those libraries.
No idea if Mach-O has any tools similar to readelf that would allow you to dump
the debug info of object files, if not, you'll need to check for it at the
assembler level (-save-temps plus -dA).

--- Comment #29 from howarth at nitro dot med dot uc dot edu 2009-09-21 17:07 --- Do we even know for certain that older versions of bintuils really work properly with the newer dwarf3/dwarf4? I wonder how much of the general instability in the recent bootstraps might be related these types of changes. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41405

OK. this is what I've done
(a) bootstrapped with Jakub's path but modified thus
Common Report Var(dwarf_strict) Init(1)
- bootstrap succeeds (with the four errors mentioned in #26).
(b) I then hand edited gcc/options.c to set dwarf_strict=0; and re-made xgcc.
Now I have a built complier that responds to the -gstrict_dwarf flag.
so I made a very simple source file:
int testfunc(void)
{
int ;
i=1;
return i;
}
I can compile this with/without -gstrict-dwarf and cmp says the .o files are
the same. -save-temps -fverbose-asm says that gstrict-dwarf is being turned on
off.
dwarfdump succeeds with everything but --debug-frame
:Assertion failed: (reg_state_pos != cie-initial_state.regs.end()), function
ParseInstructions,
(note that for this simple file the debug-str; segment is empty - which is the
error case in the four lib ones).
any guru gonna point me to where to go next ... it's really difficult to know
where the problem really lies right now.
