GraphBuilder::try_inline_intrinsics() does profiling (lines 3654 - 3669 and line 3678). append_crypto_cbc_aes() doesn’t. You should probably move the profiling code lines 3654 - 3669 and line 3678 in their own methods and call them from append_crypto_cbc_aes().

In GraphBuilder::append_crypto_cbc_aes(), InstanceOf should be passed NULL instead of copy_state_exhandling().

Otherwise, it looks good to me.

Roland.
