Does GHC supports/has a command for counting total beta reductions taken by a
program?
Thanks.

This doesn't make a whole lot of sense. One of the reasons
GHC-compiled code is so fast is that it turns into straight-line code
whenever possible, via inlining, primitive optimizations, etc.
I suppose there could be an option for the STG machine[1] to increment
a counter on every Enter, which

I heard that a Gofer compiler (a Haskell dialect) supports counting the Beta
reductions.
Hence I thought GHC/Hugs would have a similar facility.

Hugs has, afaik, a output reduction count option somewhere. At
least it had one the last time I used it.

Yes Hugs has a option +s but it counts some sort of reductions not exactly
the beta reductions.
Thanks.
