            Bug ID: 29584
           Summary: gdb: support zstd compressed .gnu_debugdata
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: i at maskray dot me
  Target Milestone: ---

.gnu_debugdata is compressed with xz, which is very slow to compress and
decompress.

zstd compressing with a large level (e.g. 18 used by Arch Linux packaging, =
19
used by openSUSE packaging) can be slower than xz, but the output is much
faster to decompress (e.g. time(xz -18) / time(zstd -18) > 5 for some
workload).

This depends on PR29563 .
