Hello Simon!
The compiler improvements look great!
Although running 'fulltest' one test caught core lint error:
> typecheck/should_compile T7891 [exit code non-0]
> (hpc,optasm,profasm,optllvm)
It can be reran as:
$ make fulltest THREADS=12 TEST=T7891
The result of optasm run:
=====> T7891(optasm) 3365 of 4096 [0, 0, 0]
cd ./typecheck/should_compile &&
'/home/slyfox/dev/git/ghc-validate/inplace/bin/ghc-stage2' -fforce-recomp

-fno-ghci-history -c T7891.hs -O -fasm -fno-warn-incomplete-patterns
>T7891.comp.stderr 2>&1
Compile failed (status 256) errors were:
*** Core Lint errors : in result of Simplifier ***

Thank you!
