Use gcov for line coverage info of GIMPLE code

[Shuai Wang via Gcc]

Hello,

I am aware of how to use gcov for c code line coverage collection. However,
currently I am working on a piece of GIMPLE code (did some instrumentation
on the GIMPLE code and therefore is more complex compared to the original C
code)l, and would like to collect the line coverage info of GIMPLE code
with gcov. Is it possible to do so? If so, could anyone shed some light on
this? Thank you very much.

Best,
Shuai
