     * CMakeLists.txt: Use DW_FWALLXX for C++.
2019-10-20 David Anderson
     * createirepformfrombinary.cc,createirepfrombinary.cc,
       dwarfgen.cc,irepattrtodbg.cc,ireptodbg.cc:
       Be more thorough in using config.h to check for C
       headers before #including them.
2019-10-06 David Anderson
     * createirepfrombinary.cc,dwarfgen.cc: Removed
       trailing whitespace.
2019-10-05 David Anderson
     * dwarfgen.cc: Now it has the tools (with a little
       help in libdwarf.h) to properly create an object file
       that is ELFCLASS64 but has 32 bit offsets in DWARF.
2019-10-04 David Anderson
     * ireptodbg.cc: Corrected the code implementing
       the dwarfgen.cc option --add-frame-advance-loc.
       It's always been a bit wrong.
     * dwarfgen.cc: Forgot to set the output-endianness flag bit
       in the call to dwarf_producer_init() which meant
       it defaulted to host endianness. Oops. Not the intent.
       Now set as intended (to little-endian in the test cases
       existing so far).
2019-09-22 David Anderson
     * createirepfrombinary.cc: Delete pointless empty lines
       and add code to recognize and correct for a broken gcc
       that duplicated an attribute (by dropping the duplicate).
     * dwarfgen.cc: Adds the ability to choose the output
       target size/endian/etc at runtime and gathers
       the choices conveniently together so it is
       legible. Adds a choice of generating DWARF4
       with 64bit pointers, showing by example.
       Now supports generating 64bit offset elf.
2019-09-02 David Anderson
     * dwarfgen.cc: Now running it on a big-endian machine
       (reading and writing little-endian objects) works
       properly.  Arbitrary endian combinations not
       fully supported.
     * ireptodbg.cc(specialAttrTransformations): Removed
       four lines of useless code.
2019-05-26 David Anderson
     * irepattrtodbg.cc,irepdie.h: Remove trailing whitespace.
     * irepform.h: Reformat a few lines to shorten them.
     * ireptodbg.cc: Fix indent.
2019-05-24 David Anderson
     * Makefile.am: Delete mention of config.h.in.cmake.
     * Makefile.in: Regenerate.
2019-05-22 David Anderson
     * dwarfgen.cc: Add ifdef/endif around include <stdint.h>
2019-05-20 David Anderson
     * CMakeLists.txt: No longer generates a local-build-dir
       config.h
     * config.h.in.cmake: Deleted.
2019-05-20 David Anderson
     * CMakeLists.txt: Reflects new option naming. Adds
       compiler warning options.
     * config.h.in.cmake: Adds needed standard defines such
       as cmakedefine DWARF_WITH_LIBELF.
     * createirepformfrombinary.cc,createirepfrombinary.cc:
       Add/remove comments for readability.
2019-05-14 David Anderson
     * irepframe.h: Modified an argument name to avoid
       shadowing a class-local function name. Avoiding
       a compiler warning.
2019-05-13 David Anderson
     * dwarfgen.cc: A bug in a macro shows up only
       on big-endian systems. This fixes it.
2019-05-07 David Anderson
     * CMakeLists.txt: Deleted a debugging message().
2019-05-01 David Anderson
     * configure.cmake: Deleted.
     * CMakeLists.txt: Now does its configure_file on its own.
2019-05-01 David Anderson
     * configure.cmake: Removed some lines, placing them in
       base directory configure.cmake.
2019-04-28 David Anderson
     * config.h.in.cmake, configure.cmake: Deleted all reference to
       INT32 and INT64 as no longer needed.
2019-04-26 David Anderson
     * config.h.in.cmake,configure.cmake: Now deals with
       latest cmake libdwarf options.
2019-04-25 David Anderson
     * createirepfrombinary.cc: Corrected the test for _MSC_VER.
2019-04-22 David Anderson
     * createirepfrombinary.cc: Add test for _MSC_VER for Windows MSVC.
2019-03-07 David Anderson
     * irepdie.h: The IRAttr assignment constructor
       had a memory leak. Fixed.
     * general.h: Added #ifndef GENERAL_H to make inclusion
       idempotent.
     * ireptodbg.cc: Using new IRAattr member function
       dropFormData to ensure immediate delete of formdata_.
       Not really needed since it would eventually be
       delete-d anyway by the destructor.
2019-03-04 David Anderson
     * dwarfgen.cc: Updated the comment about the libdwarf interface
       call return values.
     * irepattrtodbg.cc: Changed the libdwarf producer function calls
       to be the newer version returning an int as that version
       is simpler to work with. The old interfaces still exist
       and work the same as always.
     * irepdie.h: setFormData() was failing to account for
       a replacement value of formdata_, which could leak
       memory.
     * ireptodbg.cc: Replaced calls to libdwarf producer that
       returned DW_DLV_NOCOUNT or DW_DLV_BADADDR with the ones
       returning an int for improved readability of the code.
       The old functions still exist and work as always but
       we're not using them here.
2019-02-18 David Anderson
     * configure.cmake: Now defines DWARF_WITH_LIBELF
       for consistency with other cmake files.
     * dwarfgen.cc: Trivial comment correction.
2019-02-12 David Anderson
     * dwarfgen.cc: The new option --add-sun-func-offsets
       tests whether the DW_AT_SUN_func_offsets data can
       be written (and later read) properly.
     * general.h: Added bool addSUNfuncoffsets.
     * irepattrtodbg.cc: Now we handle DW_FORM_CLASS_BLOCK.
     * irepform.h: Refine IRFormBlock to make it usable.
     * ireptodbg.cc: When requested, add a
       DW_AT_SUN_func_offsets attribute to a compile unit.
2019-02-08 David Anderson
     * ireptodbg.cc: std::list<Dwarf_Unsigned> adval
       was using a non-portable initializer. Now using
       standard C++ list initializer.
2019-01-31 David Anderson
     * dwarfgen.cc,dwarfgen/ireptodbg.cc: Fixing issues
       reported by the llvm scan-build tool.
2019-01-20 David Anderson
     * dwarfgen.cc: Remove use of uint32_t and uint64_t
       and use Dwarf_Unsigned for arithmetic.
2019-01-14 David Anderson
     * createirepfrombinary.cc: Made a partial step toward
       being able to read eh_frame, but those few lines
       are ignored for now.
     * dwarfgen.cc,general.h: Adding --add-frame-advance-loc option
       which causes testing of the new DW_CFA_advance_loc
       emitting code (better portability of the code).
     * irepframe.h: Changed index results from signed
       to unsigned. Negative values never meant anything.
     * irepresentation.h: Added code for eh_frame.
     * ireptodbg.cc: We now use the improved DW_DLV_OK
       producer calls so we changed away from allowing
       indexes to be negative, we do not need to allow
       that any longer.  Now uses the latest libdwarf
       producer calls for frame data.
       If --add-frame-advance-loc then emit particular
       values of advance_loc to test the code paths
       in the DW_CFA_advance_loc* logic.
       We create a whole new cie/fde pair for  the new
       fde testing output.
2019-01-02 David Anderson
     * ChangeLog: Renamed ChangeLog2018
     * Makefile.am: Addec ChangeLog2018 to dist files.
