New Revision: 176653

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=176653
Log:
    * dwarf2.h (DW_AT_GNU_macros): New.
    (enum dwarf_macro_record_type): New enum.  Add DW_MACRO_GNU_*.

    * dwarf2out.c (struct macinfo_struct): Change code to unsigned char.
    (DEBUG_MACRO_SECTION, DEBUG_MACRO_SECTION_LABEL): Define.
    (dwarf_attr_name): Handle DW_AT_GNU_macros.
    (dwarf2out_define): If the vector is empty and
    lineno is 0, emit a dummy entry first.
    (dwarf2out_undef): Likewise.  Remove redundant semicolon.
    (htab_macinfo_hash, htab_macinfo_eq, output_macinfo_op,
    optimize_macinfo_range): New functions.
    (output_macinfo): Use them.  If !dwarf_strict and .debug_str is
    mergeable, optimize longer strings using
    DW_MACRO_GNU_{define,undef}_indirect and if HAVE_COMDAT_GROUP,
    optimize longer sequences of define/undef ops from headers
    using DW_MACRO_GNU_transparent_include.  For !dwarf_strict
    emit a section headers.
    (dwarf2out_init): For !dwarf_strict set debug_macinfo_section
    and macinfo_section_label to DEBUG_MACRO_SECTION
    resp. DEBUG_MACRO_SECTION_LABEL.
    (dwarf2out_finish): For !dwarf_strict emit DW_AT_GNU_macros
    instead of DW_AT_macro_info.

Not a Fortran problem.  Change the component to 'debug'.

Created attachment 24914
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24914
fix PR49901

The output from the tests is a little misleading.

These tests also set other flags in addition to those listed; including
-gno-strict-dwarf  ... 
... which exposes the Darwin back-end to the new .debug_macro section, for
which it has no suitable section description.

Choices; 
1) skip the tests on Darwin.
2) provide the section - although that doesn't imply that the remainder of the
tool-chain will do anything useful with it.

Here's an untested patch for choice 2.

If the tests succeed, I think your patch is good.
Users that use -gno-strict-dwarf on Darwin must know what they are doing.

works for me on Darwin9 & Darwin10.  
Don't have access to Darwin11 as yet - but if someone could check it there.

Could the patch in comment #3 be applied without waiting for an answer about
what to do with the -gno-strict-dwarf option on strict-dwarf platforms?
