Thanks Jack, I'll take a look at this info, if necessary.
a couple of points;
this below has subsequently been replaced with an #undef of the target hook in
config/darwin10.h
> - if (! for_eh)
> + /* Suppress unwind labels when targeting 10.6 or later. */
> + if ((! for_eh) || (darwin_macosx_version_min &&
> strverscmp(darwin_macosx_version_min, "10.6") >= 0))
> return;
this below is no longer properly functional with the new arrangement of options
processing.
(the test is now done in opts.c - if you leave this in you get a false warning
when -fno-exceptions is given on a g++ command line)
> + /* Disable -freorder-blocks-and-partition for exception handling or when
> + the target requested unwind info. */
> + if (flag_reorder_blocks_and_partition && (flag_exceptions ||
> flag_unwind_tables))
> + {
> + inform (input_location,
> + "-freorder-blocks-and-partition does not work with exceptions
> on
> this architecture");
> + flag_reorder_blocks_and_partition = 0;
> + flag_reorder_blocks = 1;
> + }
