|
<p>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</code> 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</code> 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</code> stab
|
||
|
|
was the address of the alternate entry point, but I don’t know the
|
||
|
|
source for that information.
