gcov apis are hidden in libgcov.a of arm-none-eabi

[Ben vin <benvinkorea@xxxxxxxxx>]

I am new to gcc and downloaded the built toolchain version
gcc-arm-none-eabi-5.2.2015q4.

But the gcov apis like __gcov_flush and init apis are hidden in libgcov.a.

How can I link this library with my test application and invoke these apis?

What am I doing wrong ?

Regards,
Ben.
