fasmw 1.73

Code:

macro vecAdd v1=we1,v2=we2 { local .a
                             movups xmm0,dqword [v1]
                             movups xmm1,dqword [v2]
                             addps  xmm1,xmm0
if ~defined we1 | @f
jmp .a
we1 dd 0,0,0,0
we2 dd 0,0,0,0
.a:
end if
}
Start:  vecAdd ;ok
        vecAdd  ;fasm error symbol we1 already defined.

I want ignored data we1 and we2 in second vecAdd

this work.

Code:

macro vecAdd v1=we1,v2=we2 { local aa
                             movups xmm0,dqword [v1]
                             movups xmm1,dqword [v2]
                             addps  xmm1,xmm0
if ~definite we1

 jmp aa
we1 dd 0,0,0,0
we2 dd 0,0,0,0
aa:
end if

}
Start:  vecAdd
        vecAdd

You can try multisection mode:

Code:

macro vecAdd v1=we1,v2=we2 { local aa
                             movups xmm0,dqword [v1]
                             movups xmm1,dqword [v2]
                             addps  xmm1,xmm0
  .dataonce vecAdd
     we1 dd 0,0,0,0
     we2 dd 0,0,0,0
  .code
}
Start:  vecAdd
        vecAdd

Or even like this:

Code:

macro vecAdd v1=we1,v2=we2 { local aa
                             movups xmm0,dqword [v1]
                             movups xmm1,dqword [v2]
                             addps  xmm1,xmm0
  ..dataonce we1, we1 dd 0,0,0,0
  ..dataonce we2, we2 dd 0,0,0,0
}
Start:  vecAdd
        vecAdd

Or even by stream:

Code:

macro vecAdd v1=we1,v2=we2 { local aa
                             movups xmm0,dqword [v1]
                             movups xmm1,dqword [v2]
                             addps  xmm1,xmm0
  .frameonce vecAdd
     we1 dd 0,0,0,0
     we2 dd 0,0,0,0
  .code
}
.multisection
section .data data readable writeable
  .stream vecAdd
section .code code readable executable
Start:  vecAdd
        vecAdd

Any of this examples will free your code from using extra jumps at least
