Disabling LTO for merge request stage2 builds?
When submitting merge requests a lot of the CI time is spent doing link-time optimization of the stage2 LLVM build. This seems unnecessary for initial testing and could significantly reduce pipeline run time.
I have configured the CUCL LLVM Jenkins instance to build pull requests without LTO and only enable LTO for the master+dev branches. Possibly this also makes sense for the Morello CI setup?
