Feature added by: Richard Biener (rguenther) Feature #322957, revision 1 Title: Use DWZ to shrink the size of debuginfo Requested by: Richard Biener (rguenther) Partner organization: openSUSE.org Description: RPM can use DWZ (DWARF compressor) to shrink the size of debuginfo. This has the chance to shrink debuginfo to half or more dependent on how many libraries / binaries a package contains. DWZ generates regular DWARF, when applicable the consumers need to know about .gnu_debugaltlink which is eventually added to debuginfo objects to refer to another debuginfo object where common DWARF split out from multiple debuginfo objects is stored. Business case (Partner benefit): openSUSE.org: Smaller (debug-)media, less download time, smaller footprint on disk, faster gdb startup (parsing less dwarf). -- openSUSE Feature: https://features.opensuse.org/322957
