That talk doesn't load for me, sorry if I ask something answered in there. How does this relate to debuginfo compression such as passing -Wl,--compress-debug-sections=zlib ? I haven't tested on very relevant programs but on a single C file (tested with vmtouch, compiled with f32's `gcc -g vmtouch.c` and `gcc -g vmtouch.c -Wl,--compress-debug-sections=zlib`) I see a fairly significant reduction in size: after strip --only-keep-debug it goes down from 32K to 23K, that's 28% down. On a slighly bigger project (wlroots), with LDFLAGS=-Wl,--compress-debug-sections=zlib meson builddir and the same strip; I'm going from 1512 to 732k that's over 50% reduction. As far as I can see, gdb and lldb both support it just fine; and the linux kernel builds with it if CONFIG_DEBUG_INFO_COMPRESSED is set so it looks widespread enough. If not related would it be worth using? Is support somehow still lacking?
