and with NIR, that already emits MADs always:

There are some particularly exciting individual improvements too:
kerbal-space-program/667: FS SIMD8: 1024 -> 561 (-45.21%)
kerbal-space-program/676: FS SIMD8: 1021 -> 558 (-45.35%)
From how old Kerbal version these shaders are from?
I just noticed that recent Kerbal outputs large amount of register spill
& alloc failure messages with INTEL_DEBUG=perf, whereas output I've
saved from a last year Kerbal version, had much less of them.
rocketbirds-hardboiled-chicken/fp-2: FS SIMD8: 1076 -> 582 (-45.91%)
Changing the fs_visitor and fp backend to always emit MADs is a little
like moving the goal posts for switching to NIR, but I think always
emitting MADs this is the right direction, and of course we'll discover
more improvements the more we work with the code.

PS. output from games using Unity3D engine goes to:
~/.config/unity3d/<company>/<game>/Player.log
Using Apitrace replay makes seeing the warnings easier. :-)
