Your function:

PHP Code:

swap(&a, &b)
{
    a = a + b - (b = a);
} 


Code:

proc	; swap
lref.s.pri c
push.pri
lref.s.pri 10
pop.alt
add
push.pri
lref.s.pri c
sref.s.pri 10
pop.alt
sub.alt
sref.s.pri c
zero.pri
retn

The simplest function:

PHP Code:

swap(&a, &b)
{
    new
        c = a;
        
    a = b;
    b = c;
} 


Code:

proc	; swap
stack fffffffc
lref.s.pri c
stor.s.pri fffffffc
lref.s.pri 10
sref.s.pri c
load.s.pri fffffffc
sref.s.pri 10
stack 4
zero.pri
retn

Fatest function without using a 3rd var.

PHP Code:

swap(&a, &b)
{
    #emit LREF.S.pri a
    #emit LREF.S.alt b
    #emit SREF.S.pri b
    #emit SREF.S.alt a
}
