It is in crypto/ec.

Which version of OpenSSL are you using? In both 0.9.8 and 1.0.0-beta it

I'm afraid that it is not a good code to study ecc.

Implementation, which is currently in OpenSSL is full of obscure
performance hacks and is not well-documented. 

When I've used it to implement GOST R 34.10-2001 algorithm in the ccgost
engine, it took some pain to understand even knowing the math and having
standard text handy.
