6 hoursoemu: cpu: Decode the BR instructionIan Moffett
Add support for interpreting the BR (branch) instruction. This instruction takes in a single register operand containing an address to reassign the instruction pointer to. Signed-off-by: Ian Moffett <ian@osmora.org>
6 hoursoemu: types: Add addr_t typeIan Moffett
The addr_t type represents any kind of memory address. We also assign paddr_t to addr_t. Signed-off-by: Ian Moffett <ian@osmora.org>
