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 table to keep track of labels	Ian Moffett
	Implement a hash table used to store a maximum of 128 labels. This commit adds functions such as label_enter() to add labels to the table, label_lookup() to lookup labels as well as various utility functions used internally by the assembler. Signed-off-by: Ian Moffett <ian@osmora.org>
4 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>

4 days	oasm: Add initial support for labels	Ian Moffett
	A label is like a pin on a map with a number attached to it. OASM keeps track of a number referred to as the psuedo instruction pointer (PIP). This value is initially zero by default and is incremented every instruction. The purpose of this value is to pin a location in the code and mark it to be at a specific address so that further references to that label would be translated to the previous PIP value at the time of encountering the label.
