I've been pretty busy in my life recently, but I finally got around writing this blog post. Hopefully, things are sorted out in my personal life and I should be able to be more regular about these updates in the future.

I'm very happy to see good progress towards rustup distribution (thanks to Kobzol again!).

The setup to be able to use LTO is non-trivial for now (I hope to be able to fix this soon so that liblto_plugin.so is not required for the case where a linker plugin wasn't not asked by the user, which is the default).

You need to have in your path the gcc built with the same version as libgccjit, which contains libexec/gcc/x86_64-pc-linux-gnu/15.0.0/liblto_plugin.so.
