 @deftypefn {Target Hook} int TARGET_SCHED_VARIABLE_ISSUE (FILE *@var{file}, int @var{verbose}, rtx @var{insn}, int @var{more})
 This hook is executed by the scheduler after it has scheduled an insn
 from the ready list.  It should return the number of insns which can
-still be issued in the current cycle.  Normally this is
-@samp{@w{@var{more} - 1}}.  You should define this hook if some insns
