|
|
<p>Most languages allow the main program to have any name. The
|
|
<code>N_MAIN</code> stab type tells the debugger the name that is used in this
|
|
program. Only the string field is significant; it is the name of
|
|
a function which is the main program. Most C compilers do not use this
|
|
stab (they expect the debugger to assume that the name is <code>main</code>),
|
|
but some C compilers emit an <code>N_MAIN</code> stab for the <code>main</code>
|
|
function. I’m not sure how XCOFF handles this.
