Op-codes
Here follows a listing of all currently implemented op-codes for the assembler, and their meaning.
add dest, src
Compute dest += src, where dest and src are operands of the same size, either
signed or unsigned.
sub dest, src
Compute dest -= src, where dest and src are operands of the same size, either
signed or unsigned.
mov dest, src
Copy one value from src to dest, i.e. dest = src.
cmp a, b
Compare a and b, and store information in the flags. Use a jmp or setCond to read the
flags.
jmp to
Jump to another location in the code (usually a label). Jumping into or out of blocks is not supported at the moment, as that will not properly handle creation and destruction of variables in the local scope. As scopes are not yet implemented, this is not a problem.
jmp cond, to
As above, but only jumps if the condition is true.
