            Bug ID: 29563
           Summary: gdb: support zstd for SHF_COMPRESSED debug sections
           Product: gdb
           Version: unknown
            Status: NEW
          Severity: normal
          Priority: P2

  Target Milestone: ---

Zstandard is a "universal" compression algorithm which scales from
low-ratio-very-fast to high-ratio-pretty-slow.
The generic-abi proposal https://groups.google.com/g/generic-abi/c/satyPkuM=
isk
("Add new ch_type value: ELFCOMPRESS_ZSTD") has been approved.

See https://sourceware.org/bugzilla/show_bug.cgi?id=3D29397 for binutils fe=
ature
request.

gdb will need to support SHF_COMPRESSED (ch_type=3DELFCOMPRESS_ZSTD) .debug=
_*
sections in executables, shared objects, and (split DWARF) .dwo files.
