[fasmg][x86] Missing/incomplete instructions macros

I generaly use fasmg for write high performance functions. So sometimes I have to use "seldom used instructions". I've noticed that instruction "prefetchw" have no macro in "fasmg package". I wrote my own based on macros for "prefetcht* instructions:

Code:

macro prefetchw? src*
        x86.parse_operand @src,src
        if @src.type = 'mem'
                if @src.size and not 1
                        err 'invalid operand size'
                end if
                x86.store_instruction <0Fh,0Dh>,@src,1
        else
                err 'invalid operand'
        end if
end macro

Also I found that "movnti" macro works only with 32 bits registers. I try to improve this macro to use also 64 bits registers:

Code:

macro movnti? dest*,src*
        x86.parse_operand @dest,dest
        x86.parse_operand @src,src
        local size
        if @dest.size = 0 & @src.size = 0
                err 'operand size not specified'
        else if @dest.size <> 0 & @src.size <> 0 & @dest.size <> @src.size
                err 'operand sizes do not match'
        else
                size = @dest.size or @src.size
        end if

        if @dest.type = 'mem' & @src.type = 'reg'
                if size <> 4 & size <> 8
                        err 'invalid operand size'
                end if
                x86.select_operand_prefix @dest,size
                x86.store_instruction <0Fh,0C3h>,@dest,@src.rm
        else
                err 'invalid combination of operands'
        end if
end macro
