#4856: Performance regression in the type checker regression for GADTs and type
families
---------------------------------+------------------------------------------
Reporter: chak | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler (Type checker)
Version: 7.0.1 | Keywords:
Testcase: | Blockedby:
Os: Unknown/Multiple | Blocking:
Architecture: Unknown/Multiple | Failure: Compile-time performance bug
---------------------------------+------------------------------------------
Comment(by chak):
I should probably point out that the performance regression is dramatic.
Instead of a few seconds, `Smart.hs` takes something like 10min on my
laptop to compile. It makes it practically infeasible to work at
Data.Array.Accelerate with 7.0.1 (or the HEAD).
