3 days	oasm: Introduce encoding for the NOP instruction	Ian Moffett
	The NOP (no operation) instruction simply tells the processor to do nothing. This can be useful for various things such as padding, timing, etc. -- nop nop nop ... -- Signed-off-by: Ian Moffett <ian@osmora.org>
3 days	oasm: Add encoding for MRO type instructions	Ian Moffett
	This commit introduces encoding logic for 4 additional instructions: - MROB (Mask Register Over [byte]) - MROW (Mask Register Over [word]) - MROD (Mask Register Over [dword]) - MROQ (Mask Register Over [qword]) This instruction is used to fill a register with a specific length of zeros or ones. For example, to fill a register (e.g., x2) with 16-bits of 1s: -- !! !! Clear bits x2[7:0]... Mrrp,, !! mrow!! !! mrow x2, #1 -- Similarly, an operand of zero sets it to zero. For example, to clear an entire 64-bit register with zeros. Something like this can be done: -- mroq x1, #0 -- Signed-off-by: Ian Moffett <ian@osmora.org>

6 days	oasm: emit: Don't use TAILQ_FOREACH for processing	Ian Moffett
	In order to have more control over the flow at which we grab the next tokens, we should roll our own loop by hand using TAILQ_FIRST() and TAILQ_NEXT() Signed-off-by: Ian Moffett <ian@osmora.org>
