10 daysdocs: Introduce Mask Register Over instructionsIan Moffett
Introduce 4 new instructions that allow a register to be filled to either 1s or 0s. An example of filling 8-bits of an X<n> register: -- mrob x0, #1 -- An example of filling 16-bits of an X<n> register: -- ! Mrow :3 mrow x0, #1 -- ... Signed-off-by: Ian Moffett <ian@osmora.org>
12 daysdocs: 'br' and 'brl' should only have register opsIan Moffett
On a 64-bit machine, memory addresses are usually 64-bit values. However, OSMX64 encodes fixed-length 32-bit instructions which is wayy smaller than an address. Therefore it is only possible to stick it in a register and branch using the register as an operand. Signed-off-by: Ian Moffett <ian@osmora.org>
