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 loosely corresponds to a beta reduction, but the STG machine is only an island in the sea of compiled code GHC creates. - ryan [1] http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.53.3729 On Fri, Nov 21, 2008 at 8:46 PM, kk08 <kdamodar2000@gmail.com> wrote:
Does GHC supports/has a command for counting total beta reductions taken by a program?
Thanks.
