| | | Associating Labels with Procedure Entry Points |
To enable you to generate correct code for calls, I have included
a component in the declaration descriptor format used for
procedures named entrylbl. It is intended
to hold the "code label" placed on the first line of the actual
code for the procedure. It will be used whenever you need to generate
a JSR to the procedure.
The type of the entrylbl field is determined by the value of
the #define CODELBL. If you do not include a #define
for CODELBL, it defaults to the type char.
However, if you have declared a special type to hold code labels,
you can #define CODELBL to be the name of that type.
For example, if your type's name was
codelabel, you would
simply include the define
#define CODELBL codelabelsomewhere before the
#include for symtab.h. The definition
of codelabel will also have to precede this include in most cases.
While I have included the entrylbl field in each procedure declaration
descriptor, it is up to your code to set this field.
