Go doesn't have an instruction (execution) or function call tracer. Go's tracer is primarily tracing scheduler events. So maybe the term scheduler tracer should have been used?

Anyway, using the term "execution tracer" in Go goes back to the initial design doc from 2014: https://docs.google.com/document/u/1/d/1FP5apqzBgr7ahCCgFO-y...
