    Now mentions mmap() is usable only
    on Elf object files. Other objects always use malloc().

    commit 7f7df06c5b16e5a0edd0730adbd1566777989eb4

    Updated date to April 2.
            modified:   doc/libdwarf.dox
            modified:   doc/libdwarf.pdf
    Added fuller explanation of the use of
    shell envronment variable 'DWARF_WHICH_ALLOC'
    to influence the use of malloc() vs mmap().
    mmap() is only usable (in this release) on Elf
    object files.

    Added these to the list of arguments that

    commit 08ff7580f0afe0ea9b4ba61092cc545512e4360e

    On linux gdb and valgrind  and libc notice
    that printf of sequential byte pairs, where
    the byte-pairs accidentally overlap (!) due
    to a mistake in this source... is bogus.

    MacOS notices too, but it reports "Trace/BPT trap: 5"
    which is quite mysterious.
    This is a serious bug which has been in place
    since support for the DWARF5 .debug_names section
    was added.  It crashes the app reading the .debug_info
    section reliably.

    Of course simplereader is just an example, but
    still...needs to be correct

    It had been hidden from testing before due to an oversight in
    the  debugfissionb directory in regressiontests
    was coded. We now prevent corrupt
    DWARF with duplicated attributes in a PE file from
    showing an error and avoiding
    any meaingful test. Just for this case.
    So the tests are now fixed too.

2025-03-28:  David Anderson
    commit ad7d97b0434757cb3f43b77e0c322ae5005af9cf

    Added and documented
    dwarf_language_version_string()
    to the API so programs can interpret the
    version (as an integer) in detail should
    they wish to do so.

    The intent is the actual version is an integer
    and trivial to compare.  It's possible
    (though highly unlikely) that a real version
    might not be representable directly.
    DW_AT_language_version is a DWARF class CONSTANT,
    not a string.

    Regenerated with 'make rebuild' using configure
    and now including dwarf_get_LNAME_name()
            modified:   src/lib/libdwarf/dwarf_names.c

    Added the DW_LNAME logical compiler naming from
    DWARF6.  dwarfstd.org says these are things which
    will not change (more may be added) and compilers
    are explicitly allowed to generate DW_LNAME.
            modified:   src/lib/libdwarf/libdwarf.h
    Added the function prototype dwarf_get_LNAME_name()
    which returns the ascii string, such as
    "DW_LNAME_C" when 0x03 is passed in.

    commit 43831b87e10e1e2503b625611ab66e00e256e4aa

    This completes the work for release 0.12.0
    (release date not yet scheduled) which enables
    use of mmap or malloc/read when libdwarf
    accesses object section data.

    A major compatibility break requiring
    code calling the library be recompiled with
    the new library.

    Systems without the functions/data to use mmap
    will compile normally, though the compatibility
    break is still applicable.

    Small changes may be required before release.

    Normal automatic update.

    commit 1295c345a7990f6600df56ff22f9db41e1a51efd

    Now handles unmap and record keeping
    for using mmap instead of malloc/read on section content.
    Nothing here yet for mapping or choices of which
    to use.

    commit 304e3b74896c4010fdddcb3ba9fd1f60a4f8c765

    For large sections (like .debug_info) avoid preloading the
    hash table recording allocation with a gigantic
    allocation.  If necessary it will later increase
    the allocation automatically.

    commit ed74b438dcbbf74759a15324c93d924191823ea7

    As of 6 January 2025 the DWARF committee
    voted to make W_AT_language_name
    and DW_AT_language_version from DWARF6
    immutable values now.  So compilers wishing
    to add either or both to DWARF5
    compiler output are officially allowed to use
    these now.
