Hence my suggestion to use label rather than constants.  (They could be
.Lsparc_get_pc_thunk_foo labels instead of numeric ones to avoid Dave's
concern about users of the macro already using numeric labels, unless the
macro is used more than once in a file--in which case, perhaps the whole
thing should be in gas macros that can use \@ for gensym labels.)


Thanks,
