@node Alternate Entry Points
@section Alternate Entry Points
Some languages, like Fortran, have the ability to enter procedures at
some place other than the beginning. One can declare an alternate entry
point. The @code{N_ENTRY} stab is for this; however, the Sun FORTRAN compiler
doesn't use it. According to AIX documentation, only the name of a
@code{C_ENTRY} stab is significant; the address of the alternate entry
point comes from the corresponding external symbol. A previous revision
of this document said that the value of an @code{N_ENTRY} stab was the
address of the alternate entry point, but I don't know the source for
that information.
