Understanding Haskell profiler output - what is ==_a3JO
ghc, haskell, profiling
Solution
Does `distanceRad` have an `Eq` instance as an argument? I've only used the profiler a few times, but it looks like it's an instance implementation of `(==)` that has been name-mangled to be unique.
(Posting the code might help.)
Problem
I am writing some optimization application in Haskell and I just ran it through profiler. I can see many functions and a strange symbol "==_a3JO" (sometimes different numbers and leters). What does it stand for? Sample output: ``` maxDistanceRaw Igc 360 471912 5.2 5.7 19.8 20.3 distance Igc 364 30143010 1.3 1.0 14.6 14.6 distanceRad Igc 365 30143010 10.4 8.8 13.3 13.6 ==_a3JO Igc 366 30143010 2.9 4.9 2.9 4.9 ==_a3JO Igc 350 233432454 35.3 36.9 35.3 36.9 ```
