dwarves-1.27-3.1 RPM for x86_64

From OpenSuSE Tumbleweed for x86_64

dwarves is a set of tools that use the DWARF debugging information
inserted in ELF binaries by compilers such as GCC, used by well known
debuggers such as GDB, and more recent ones such as systemtap.

Utilities in the dwarves suite include pahole, that can be used to
find alignment holes in structs and classes in languages such as C,
C++, but not limited to these.

It also extracts other information such as CPU cacheline alignment,
helping pack those structures to achieve more cache hits.

A diff like tool, codiff can be used to compare the effects changes
in source code generate on the resulting binaries.

Another tool is pfunct, that can be used to find all sorts of
information about functions, inlines, decisions made by the compiler
about inlining, etc.

  - update to 1.24:
    * Add support to BTF_KIND_ENUM64 to represent enumeration
      entries with more than 32 bits.
    * Support multithreaded encoding, in addition to DWARF
      multithreaded loading, speeding up the process. Selected just
      like DWARF multithreaded loading, using the 'pahole -j'
      option.
    * Encode 'char' type as signed.
    * Add support to BTF_KIND_ENUM64.
    * Introduce --lang and --lang_exclude to specify the language
      the DWARF compile units were originated from to use or
      filter.
    * Introduce --compile to generate compilable code in a similar
      fashion to: bpftool btf dump file vmlinux format c >
      vmlinux.h As with 'bpftool', this will notice type shadowing,
      i.e. multiple types with the same name and will disambiguate
      by adding a suffix.
    * Don't segfault when processing bogus files.
  - add dwarves.keyring for source validation

      objects with more than 65534 sections, for instance, which
      happens with kernels built with KCFLAGS="-ffunction-sections
    - fdata-sections", Other cases may include when using FG-ASLR,
      LTO.
    * Fix BTF variable generation for kernel modules, not skipping
      variables at offset zero.
    * Fix address size to match what is in the ELF file being
      processed, to fix using a 64-bit pahole binary to generate
      BTF for a 32-bit vmlinux image.
* Wed Jan 06 2021 Gary Ching-Pang Lin <glin@suse.com>
  - Drop the version requirement of libdw-devel
    + DW_AT_alignment is defined in 1.19 so dwarves now is compatible
      with older libdw.
