   1 * local labels
   2 * two forms, $[0-9] and label? are allowed
   3 * Local labels are undefined/reset in one of four ways:
   4 * .newblock
   5 * changing sections
   6 * entering an include file
   7 * leaving an include file
   8         .global addra, addrb, addrc
   9 label1: ld      addra,a
  10         sub     addrb,a
  11         bc      $1, alt                 ; generates frag!
  12         ld      addrb, a
  13         b       $2
  14 $1:     ld      addra,a
  15 $2      add     addrc,a
  16         .newblock

  21 * #1, First definition of local label 'lab'
  22         nop
  23 lab?    add     #1,a                    ; reports as line 17?
  24         b       lab?
  25 * #2, Included file also defines local label 'lab'
  26         .copy labels.inc
  27 * #3, Next definition; exit from .copy clears all locals
  28 lab?    add     #3,a                    ; reports as line 22?
  29         b       lab?
  30 * #4, Next definition is within macro; supersedes previous definition while
  31 * within the macro
  32 mac     .macro
  33 lab?    add     #4,a                    ; line 31?
  34         b       lab?
  35         .endm
  36 * Macro invocation
  37         mac
  38 * This reference should resolve to definition #3
  39 after_macro:
  40         b       lab?
  41 * Section change clears all definitions; it's a CODE section if we see insns
  42         .sect   new_section
  43         nop
  44 lab?    add     #5,a
  45         nop
  46         nop
  47         b       lab?
  48 * Newblock directive clears local labels
  49         .newblock
