dwarves-dfsg 1.20-1 source package in Ubuntu

Changelog

dwarves-dfsg (1.20-1) unstable; urgency=medium

  * New upstream release.
    Changes since 1.19:

    BTF encoder:
      - Improve ELF error reporting using elf_errmsg(elf_errno()).
      - Improve objcopy error handling.
      - Fix handling of 'restrict' qualifier, that was being treated
        as a 'const'.
      - Support SHN_XINDEX in st_shndx symbol indexes, to handle ELF
        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.
      - Cope with functions without a name, as seen sometimes when
        building kernel images with some versions of clang, when a
        SEGFAULT was taking place.
      - 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.
      - Use kernel module ftrace addresses when finding which functions
        to encode, which increases the number of functions encoded.
    DWARF loader:
      - Support DW_AT_data_bit_offset
      - DW_FORM_implicit_const in attr_numeric() and attr_offset()
      - Support DW_TAG_GNU_call_site, its the standardized rename of
        the previously supported DW_TAG_GNU_call_site.
    build:
        - Fix compilation on 32-bit architectures.

  * Refresh patches.
  * Remove ctfdwdiff and README.cross so to reuse upstream tarball as-is.
  * Update Standards-Version to 4.5.1
  * Update debhelper compatibility to 13:
    - install missing binaries: btfdiff and fullcircle
  * Add upstream metadata file
  * gbp: set upstream tarball compression to xz
  * Add lintian override for orig-tarball-missing-upstream-signature,
    see #882694.
