I don't see any sign of macros being poisoned in system.h. For macros
used in target-independent unwinder code - at least MD_FROB_UPDATE_CONTEXT
- that used to be defined in the host tm.h but now no longer should be, I
think poisoning in system.h is appropriate.

What about DWARF_ZERO_REG and PRE_GCC3_DWARF_FRAME_REGISTERS?
DWARF_REG_TO_UNWIND_COLUMN may be more complicated because it's used on
the host in rs6000.c (although not in target-independent host code) as
well as on the target - I suspect that will be a case where duplicating
the definition (with a comment in one place pointing to the other place as
needing to be kept consistent, and with the host-side copy renamed to
facilitate poisoning) may make sense. And all three are defined in
<arch>.h headers so your reason for moving them separately may apply.
(There are lots more macros used in the unwinder and on the host for which
macros predefined with -fbuilding-libgcc may be appropriate in a later
patch.)

Good point: I simply had forgotten about this.

I guess. For the moment, I've concentrated on moving the sources
themselves and the build logic since I've experienced the gcc side
getting in the way of the libgcc side here.

Certainly: your wiki entry gives a good overview. For the moment, I'll
probably concentrate on the build side of things, though. I may attack
gthr* stuff and fp-bit.[ch] next, both of which I can at least partially
test on my targets.

fp-bit.[ch] has the interesting issue of FLOAT_BIT_ORDER_MISMATCH and
FLOAT_WORD_ORDER_MISMATCH being defined by makefile rules when it ought to
be possible to deduce that information from macros predefined by the
compiler. (See what I said in
<http://gcc.gnu.org/ml/gcc-patches/2010-11/msg02262.html> about the
meanings of those macros.)
dfp-bit.* and fixed-bit.* can probably move along with fp-bit.* (or
before, or after), and I don't think there are any complicated issues
around those files.

This patch appears to create a *second* file called libgcc_tm.h, so there
is one created in gcc/ and one in libgcc/, which seems incredibly
confusing. By all means move the libgcc_tm.h logic to libgcc/ (though
tm.h will need to continue to include libgcc_tm.h for the target, until
the transition away from tm.h target macros in target code is complete and
code includes libgcc_tm.h directly instead), but don't have two headers
with the same name in different build directories.
I interpreted Rainer's comment as meaning that a
libgcc/config/mips/mips-lib.h (or similar) file would need to be created
and inserted in the right place in libgcc_tm_file for the large number of
targets presently putting mips.h in tm_file.

Yes, the patch was not complete and only meant to be the plumbing for
what you describe.
I think Rainer missed the existence of libgcc_tm_file. :)

Indeed, that's why I refrained from attacking this by other means.

I didn't, but it lives in gcc/config.gcc, which is contrary to the move
from gcc to libgcc.

Done in the updated patch below. Given that the other two are ia64 only
and not documented in md.texi, I don't think they need to be poisoned.
Otherwise, the patch is unchanged from the original submission:
[build] Move unwinder to toplevel libgcc
http://gcc.gnu.org/ml/gcc-patches/2011-06/msg01452.html
Unfortunately, it hasn't seen much comment. I'm now looking for testers
especially on platforms with more change and approval of those parts:
* Several IA-64 targets:
ia64*-*-linux*
ia64*-*-hpux*
ia64-hp-*vms*
* AIX:
rs6000-ibm-aix*
Thanks.
