Yes.

However there is an alternative that I often use: directly use A7 as the BASE register.
So simply:

    lea -gl_SIZEOF(a7),a7

  if needed
  {
    move.l    a7,A3
    move.l    #gl_SIZEOF/4-1,d1
.clr
    clr.l    (a3)+
    dbf        d1,.clr
  }
 ...
    move.l    (A1)+,(gl_chipptr,a7)

You need to have a total control over subroutine call nesting!
LINK is for high level languages where the subroutine calls is not known at priori..

You even gain a spare A register
