x32 is not a supported target. Do you have something that is reproduceable on
supported targets? ia64-hpux is the only one I think...

Steve, have you seen any DWARF regressions on ia64-hpux?

Yes, I am seeing some new failures on IA64 HP-UX. I do not get the stackalign
failures but I do get:
FAIL: g++.dg/debug/dwarf2/static-local-var-in-ctor.C scan-assembler
DW_OP_addr[^

DW_OP_addr[\\n\\r]+[^\\n\\r]+foo
These showed up between 173204 and 173229 so they are probably due to the same
change.

Created attachment 24170
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24170
gcc47-pr48853.patch
This patch should fix var2.c on ia64-hpux - the patch will for memory addresses
only (i.e. when mem_mode is not VOIDmode) allow SYMBOL_REFs/LABEL_REFs/CONST of
larger mode than DWARF2_ADDR_SIZE, assuming it is Pmode and ptr_mode has
DWARF2_ADDR_SIZE. It is a total mess though, because whether it is sign
extended or zero extended or something else isn't actually represented in the
debug info, the debug info consumer needs to know.

The patch works for me on ia64-hp-hpux11.23. It fixed the four new failures I
had and caused no regressions.

Does it fix (at least some of) the x32 issues as well? If some (e.g. ICEs) are
left, please post backtraces and other relevant details.

Can you track down on which mem_loc_descriptor call these new
DW_OP_GNU_*_type/DW_OP_GNU_{convert,reinterpret}
locs have been added, and for that post a backtrace and debug_rtx on the
outermost mem_loc_descriptor call argument?

Steve, does the latest GDB work on ia64 hp-ux? You
may see more regressions with the latest GDB.

GDB on ia64 hp-ux never really worked. It only started building this year when
Joel Brobecker ported it but I was never able to get good results with it
(either testing or in actual use).
The HP WDB (based on an old GDB) works better but still has many shortcomings
when used with GCC.
