[opensuse-factory] Using DWZ to shrink -debuginfo package size
SR#477417 changes us (rpm) to use DWZ to shrink the size of debuginfo
(by optimizing the DWARF for size and splitting out common parts from
multiple binaries / libraries into a DWARF library). Preliminary results
show a reduction in -debuginfo package size of up to 50% (it really
depends on the number of binaries/libraries plus the source language).
Projects not wanting this need to block dwz from inside their project
config via
Ignore: rpm-build:dwz
thus DWZ support is not via explicit Support: but with an added
Requires to rpm-build (like all of our core BuildRequires).

Very cool. Btw, what happened to https://gcc.gnu.org/wiki/DebugFission ? Are there plans to support that as well? -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

The implementation is far from production ready but it has been
standardized in DWARF4/5. Not sure how far tooling support is for
.dwo / .dwp. Plus I think fission doesn't actually reduce the size
of the info but is supposed to be leaner on the linker only.
