fma4 with fasmg?

The headers I published are focused on the instruction sets that ended up officially documented in Intel SDMs, and FMA4 was not among them - it was only officially supported with AMD's XOP, and I have not yet published packages for fasmg that would support AMD-specific extensions (like 3DNow! or XOP), mainly because there was no demand. With macro-based encoders it quite easy to implement new instruction sets, though, and you can support FMA4 with a simple header like:

Code:

include 'cpu/ext/avx.inc'

macro FMA4_instruction opcode,msize,dest,src,src2,src3
        AVX.parse_operand @dest,dest
        AVX.parse_operand @src,src
        AVX.parse_operand @src2,src2
        AVX.parse_operand @aux,src3
        if @dest.type = 'mmreg' & @src.type = 'mmreg' & (@src2.type = 'mem' | @src2.type = 'mmreg') & (@aux.type = 'mem' | @aux.type = 'mmreg')
                if msize & (@dest.size < msize | (@dest.size > msize & @dest.size <> 16) | (@src2.type = 'mem' & @src2.size and not msize) | (@aux.type = 'mem' & @aux.size and not msize))
                        err 'invalid operand size'
                else if @src.size <> @dest.size | (@src2.size and not @dest.size & (@src2.type = 'mmreg' | msize = 0))
                        err 'operand sizes do not match'
                end if
                if @aux.type = 'mmreg'
                        AVX.store_instruction @dest.size,VEX_66_0F3A_W0,opcode,@src2,@dest.rm,@src.rm,1,@aux.rm shl 4
                else if @src2.type = 'mmreg'
                        AVX.store_instruction @dest.size,VEX_66_0F3A_W1,opcode,@aux,@dest.rm,@src.rm,1,@src2.rm shl 4
                else
                        err 'invalid combination of operands'
                end if
        else
                err 'invalid combination of operands'
        end if
end macro

iterate <instr,opcode>, vfmaddsub,5Ch, vfmsubadd,5Eh, vfmadd,68h, vfmsub,6Ch, vfnmadd,78h, vfnmsub,7Ch

        macro instr#pd? dest*,src*,src2*,src3*
                FMA4_instruction opcode+1,0,dest,src,src2,src3
        end macro

        macro instr#ps? dest*,src*,src2*,src3*
                FMA4_instruction opcode,0,dest,src,src2,src3
        end macro

        if opcode > 60h

                macro instr#sd? dest*,src*,src2*,src3*
                        FMA4_instruction opcode+3,8,dest,src,src2,src3
                end macro

                macro instr#ss? dest*,src*,src2*,src3*
                        FMA4_instruction opcode+2,4,dest,src,src2,src3
                end macro

        end if

end iterate

I made it just now, so it not thoroughly tested - but it should be easy to tweak it if necessary.

PS. Perhaps you may also find these macros for fasm 1 interesting: Emulating FMA4 with FMA and vice versa.
