This is the second patch of the group.\r\n\r\nThis patch updates the generated encoding.h (generated from riscv-opcodes) and adds empty implementations for the custom instructions.\n\n----\n\n_**[arunthomas](https://github.com/arunthomas)** included the following code: https://github.com/ucb-bar/riscv-isa-sim/pull/4/commits_\n"}}
