Follow-up on the toolchain+mold topic: gcc's --with-lto builds a compiler with lto support, it doesn't lto the compiler itself. So as-is using mold to link the toolchain won't gain much.

To repeat myself from irc: Those ^ are the data.tar.gz file sizes in the package files, so already compressed. buildbot does things differently to my setup, so the size_compare.sh results...

Updated, with those ugly PKG_NO_* vars removed, they're now build flags, for which I created #11928. Since this build upon that I included the patches from that PR here too....

Some basic stats with the new flags. This is a basic armvirt32 filesystem with most of "Base system" selected: ``` $ du -cks root-armvirt+*|sort 18464 root-armvirt+mold+gc+lto 18488 root-armvirt+mold+lto 18692 root-armvirt+mold+gc...

Yeah, if I didn't mess it up the config knobs should reflect that already. I build a ramips image and it didn't offer any mold option and used bfd just...

Rebased, but this isn't WIP anymore for quite some time now, I've been building all my non-MIPS images with mold for month now. It's "done" in the sense that it...

While you're at it, I noticed this by coincidence: ``` -fwhole-program [snip] This option should not be used in combination with -flto. Instead relying on a linker plugin should provide...

There's probably more to it than just meson, but from that point of view I've always tried to avoid this because having to build the interpreter for a build system...
