    Use .rept

    .rept 4
  ……
  vadd.u8 q0, q2
  ……
.endr

    Edit: OK, turns out the iPhone SDK is using an ancient version of GNU as (1.38), so .rept cannot be used. You could use a macro to simulate this though, e.g.

    .macro dummy_macro_ahjd
 .if $0
  vadd.u8 q0, q2
  dummy_macro_ahjd ($0-1)
 .endif
.endmacro

main:
 dummy_macro_ahjd 4
