2010-10-13  DavidAnderson <davea42@earthlink.net>
     * dwarf.h: Added DW_LANG_Go as 0x0015 per discussion on
       mailing list.
2010-09-29  DavidAnderson <davea42@earthlink.net>
     * README: Document that there is no install target and
       update some of the old references to postscript to refer
       to pdf.
     * Makefile.in: A dummy install target provided though it
       gets ignored by make.
2010-09-20  DavidAnderson <davea42@earthlink.net>
     * libdwarf/libdwarf.h: Added commentary about markers.
     * libdwarf/libdwarf2p.1.mm: Documented the marker calls.
     * libdwarf/libdwarf2p.1.pdf: Regeenerated, ver 1.29.
2010-06-30  DavidAnderson <davea42@earthlink.net>
     * dwarf.h: Add DW_ISA_ARM values for DW_LNS_set_isa.
2010-06-01  DavidAnderson <davea42@earthlink.net>
     * README: Document issues with building on MacOSX and
       how to deal with them.
     * Makefile.in: Added comment about ar -s for MacOSX users.
     * dwarf.h: Added comment about the gap in FORM number use
       just before 0x20.
2010-03-30  DavidAnderson <davea42@earthlink.net>
     * dwarf_frame2.c: Tightned up a harmless error 
       message string and deleted an unused local variable.
     * dwarf_harmless.c: Detected more errors in the implementation
       and fixed them.
     * dwarf_elf_access.c: If EM_MIPS not defined, define it to 8,
       the standard value for EM_MIPS.
       Refine the rela relocations code for MIPS 64 BE vs LE.
     * dwarf_arange.h: Added new fields to properly represent
       segments in aranges as documented in DWARF4.
     * dwarf_arange.c: dwarf_get_aranges was thinking
       an entry with 0,0 (end of a set) was the end of the aranges
       for a CU.  But that is not guaranteed by the DWARF standards,
       there can be multiple sets in one CU, see the standard,
       section 7.20 (DWARF2,3,4).
       Created local function, removing lots of duplicated code.
       Added some support for DWARF4 segment value in tuples.
       Added dwarf_get_arange_info_b() so all DWARF4 information
       can be retrieved by client code.
     * libdwarf.h: Aded new interface dwarf_get_arange_info_b(),
2010-03-28  DavidAnderson <davea42@earthlink.net>
     * libdwarf.h: Adding dwarf_get_harmless_error_list(),
       dwarf_insert_harmless_error(), and 
       dwarf_set_harmless_error_list_size() functions.
       Some errors that are detectable are not sufficient
       to warrant rejecting an object or refusing to process it.
     * dwarf_harmless.c: Implementing
       the harmless error functions.
     * dwarf_harmless.h: Declaration of the libdwarf_internal
       dwarf_harmless_init and dwarf_harmless_cleanout functions.
     * dwarf_error.c: Added DW_DLE_DEBUG_FRAME_LENGTH_NOT_MULTIPLE
       error string.
     * dwarf_util.h: Clarify some comments on READ_AREA_LENGTH
       macro.
     * dwarf_opaque.h: Add structure and field to record
       harmless errors for a dbg.
     * dwarf_frame.h:  Add commentary. Change ci_length from 
       Dwarf_Word to Dwarf_Unsigned for consistency with other such
       length fields.
     * Makefile.in: Add dwarf_harmless.o to the list of objects.
     * dwarf_alloc.c: Add call to dwarf_harmless_cleanout() on
       close of a dbg.
     * dwarf_init_finish.c: Add call to dwarf_harmless_init 
       to initialize the fields for recording harmless errors.
     * dwarf_frame2.c: Add handling of Arm "armcc+" augmentation
       string. Create validate_length() local function to check
       that the fde/cie length matches the requirements of the
       specification, implementing  the
       DW_DLE_DEBUG_FRAME_LENGTH_NOT_MULTIPLE test (a harmless error).
       Removed an earlier formally incorrect test.
     * libdwarf2.1.mm: Documented the harmless error calls.
       The version is now 1.90.
     * libdwarf2.1.pdf: Regenerated as 1.90.
2010-02-14  DavidAnderson <davea42@earthlink.net>
     * dwarf.h: Add GNU template defines.
     * libdwarf.h: Add new error code DW_DLE_NOT_REF_FORM for
       the DWARF 4 case where DW_FORM_data4/8 no longer
       valid global reference forms.
     * libdwarf2.1.mm: Document the manner that DW_OP_implicit_value
       is returned as a location description set.
     * libdwarf2.1.pdf: Regenerate. Rev 1.89.
     * dwarf_error.c: Add two new DW_DLE error strings.
     * dwarf_frame.h: define DW_DEBUG_FRAME_VERSION4 for
       DWARF4 support. Add address size and segment size fields
       to the internal CIE structure.
     * dwarf_query.c: The form-class code was not correct,
       DWARF4 has DW_FORM_sec_offset, not DWARF3.
       Some places did not use the CU context address size
       when reading an address.
     * dwarf_form.c: Use the CU-context address size
       instead of the overall object address/offset size.
       Initialize all local variables at the point of declaration.
       Refine some commentary.
       Use the CU version number to guide processing of some FORMs.
     * dwarf_print_lines.c, dwarf_query.c: Use the CU-context 
       address size instead of the overall object address/offset size.
       Handle DW_LNE user extensions as well as possible.
     * dwarf_arange.c: Delete some erroneous code (already ifdefd out)
       as the address size need not match the de_pointer_size.
       If segment-selector non-zero, read it properly.
       DWARF2 and DWARF3 left this documented in an incorrect
       and unusable fashion (DWARF4 documents it properly).
     * dwarf_die_deliv.c: Delete erroneous code (previously ifdefd out)
       as the address size need not match the de_pointer_size.
     * dwarf_sort_line.c, dwarf_line.c: Deal with DW_DLE extended 
       line operations past those defined by the standard 
       (such as user-defined operations).
     * dwarf_line.h: For user-defined line extended operations, provide
       a sanity check of DW_LNE_LEN_MAX.
     * dwarf_base_types.h: Add DW_CIE_VERSION4 for DWARF4.
       Add other defines so each defined version number (sections
       differ) has a name for the relevant section.
     * dwarf_frame2.c: Add address size to argument lists so the proper
       CIE address size (a new field in DWARF4 CIEs) are honored.
       Also read the new DWARF4 segment_size field.
       Use the address size instead of the object-derived de_pointer_size.
     * dwarf_util.c: Return address_size instead of de_pointer_size.
     * dwarf_loc.c: DWARF4 uses DW_FORM_sec_offset, not
       DW_FORM_data4 or DW_FORM_data8 when specifying offsets to
       other sections.  Add DWARF4 DW_OP_implicit_value and
       DW_OP_stack_value.
     * dwarf_frame.c: Initialize a local variable  at the point
       of declaration.
2010-02-04  DavidAnderson <davea42@earthlink.net>
     * libdwarf2.1.mm: Fix a spelling error.
     * libdwarf2.1.mm: Regenerate. Rev 1.88.
2010-02-01  DavidAnderson <davea42@earthlink.net>
     * dwarf_frame.c: The DW_CFA_remember_state and DW_CFA_restore_state
       operations were not recording/restoring the cfa_rule, now they do.
2010-01-27  DavidAnderson <davea42@earthlink.net>
     * dwarf_form.c: form_refsig8() had an uninitialized
       local variable.
2010-01-25  DavidAnderson <davea42@earthlink.net>
     * libdwarf2.1.mm:  Rev 1.87.  Improved the discussion
       of frame information.
     * libdwarf2.1.pdf: regenerated.
2010-01-25  DavidAnderson <davea42@earthlink.net>
     * pro_opaque.h, pro_init.c, pro_section.c,
       pro_reloc_stream.c, pro_reloc_symbolic.c: Rename the function
       pointer members de_func and de_func_b to 
       de_callback_func and de_callback_func_b respectively.
2010-01-17  DavidAnderson <davea42@earthlink.net>
     * dwarf.h, libdwarf.h: Updated commentary about frame interfaces.
     * libdwarf2.1.mm: New descriptions of DW_FRAME_CFA_COL
       and DW_FRAME_CFA_COL3.   Document rev 1.86 .
     * libdwarf2.1.pdf: Regenerated.
     * libdwarf2p.1.mm: Fixed a couple of typos. Rev 1.28.
     * libdwarf2p.1.pdf: Regenerated.
     * configure.in: Added support for configure
       --enable-oldframcol.
     * config.h.in: Added support for configure
       --enable-oldframcol.
     * dwarf_init_finish.c: Added support for configure
       --enable-oldframecol (see DW_FRAME_CFA_COL and 
       DW_FRAME_CFA_COL3).  By default the frame column
       is now DW_FRAME_CFA_COL3.   --enable-oldframecol
       changes the default to DW_FRAME_CFA_COL.
     * configure: Regenerated.
     * dwarf_opaque.h: Added one blank line and deleted
       one, hopefully aiding clarity.
     * dwarf_frame.c: Added commentary about the frame
       interfaces to emphasize the newer ones.
2010-01-13  DavidAnderson <davea42@earthlink.net>
     * dwarf_print_lines.c: Changed 'include files count'
       to 'files count'.
2010-01-04  DavidAnderson <davea42@earthlink.net>
     * pro_section.c, pro_opaque.h: A pretty-print tool 
       generated some odd formatting (long ago) and there 
       were silly blank lines present as well. This makes things more
       readable.
2010-01-03  DavidAnderson <davea42@earthlink.net>
     * common.h, common.c: Remove <cr> line end characters.
       Update copyright for 2010.
     * All other files: Update copyright year.
