Where is EVP_aes_256_gcm?

[Li, David]

Hi All,
I can't find this function in the source tree? It seems pointing to 
FIPS_aes_256_gcm.  All I see is:

grep -r FIPS_evp_aes_256_gcm .
./crypto/evp/evp_fips.c:const EVP_CIPHER *EVP_aes_256_gcm(void)  { return 
FIPS_evp_aes_256_gcm(); }

Anyone know where it is?

David
