| | | | | | It avoids dividing by 8 when deserializing a tx, which is a slow operation, and multiplies by 8 when verifying and extracing the amount, which is much faster as well as less frequent

* Remove unused variables in monero codebaseKevin Barbour2021-02-091-2/+0
| | | | | | | | | | | There are quite a few variables in the code that are no longer (or perhaps never were) in use. These were discovered by enabling compiler warnings for unused variables and cleaning them up. In most cases where the unused variables were the result of a function call the call was left but the variable assignment removed, unless it was obvious that it was a simple getter with no side effects.

* | device: untangle cyclic depenencystoffu2018-03-141-7/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | When #3303 was merged, a cyclic dependency chain was generated: libdevice <- libcncrypto <- libringct <- libdevice This was because libdevice needs access to a set of basic crypto operations implemented in libringct such as scalarmultBase(), while libringct also needs access to abstracted crypto operations implemented in libdevice such as ecdhEncode(). To untangle this cyclic dependency chain, this patch splits libringct into libringct_basic and libringct, where the basic crypto ops previously in libringct are moved into libringct_basic. The cyclic dependency is now resolved thanks to this separation: libcncrypto <- libringct_basic <- libdevice <- libcryptonote_basic <- libringct This eliminates the need for crypto_device.cpp and rctOps_device.cpp. Also, many abstracted interfaces of hw::device such as encrypt_payment_id() and get_subaddress_secret_key() were previously implemented in libcryptonote_basic (cryptonote_format_utils.cpp) and were then called from hw::core::device_default, which is odd because libdevice is supposed to be independent of libcryptonote_basic. Therefore, those functions were moved to device_default.cpp.
