fakeEnvironment :: env Source #
A dummy environment that is passed to functions that create benchmarks from environments when no concrete environment is available.
nf' :: (b -> ()) -> (a -> b) -> a -> Int64 -> IO () Source #
Generate a function which applies an argument to a function a given number of times, reducing the result to normal form.
whnf' :: (a -> b) -> a -> Int64 -> IO () Source #
Generate a function which applies an argument to a function a given number of times.
SPEC is used by GHC in the SpecConstr pass in order to inform
the compiler when to be particularly aggressive. In particular, it
tells GHC to specialize regardless of size or the number of
specializations. However, not all loops fall into this category.
Libraries can specify this by using SPEC data type to inform which
loops should be aggressively specialized.
