.extendedexpects zero or more flonums, separated by commas; for each flonum, ‘.extended’ emits an ieee extended-format (80-bit) floating-point number.
calljinstruction to enable faster calls of leaf procedures. If a procedure is known to call no other procedures, you may define an entry point that skips procedure prolog code (and that does not depend on system-supplied saved context), and declare it as the bal-lab using ‘.leafproc’. If the procedure also has an entry point that goes through the normal prolog, you can specify that entry point as call-lab.
A ‘.leafproc’ declaration is meant for use in conjunction with the
optimized call instruction ‘callj’; the directive records the data
needed later to choose between converting the ‘callj’ into a
bal or a
call-lab is optional; if only one argument is present, or if the
two arguments are identical, the single argument is assumed to be the
bal entry point.
Both arguments are required; index must be between 0 and 31 (inclusive).
