> This is still work in progress as it currently breaks a few tests. Mainly, it seems to influence which copies are local and which are non-local, which influences the order in which the RegisterCoalescer visits copies. Coalescing the wrong registers first has unwanted side-effects.
What does this mean for the livability of this patch?
