Language Implementation

For information on the
function table, refer to the i960 Processor Assembler User's Guide.
You must associate a single system procedure table index with each
system function before the final link of your program. The linker
generates an error message for any system function that has no index or
multiple conflicting indexes.
You can make this association in either or both of the following ways, if
the defined index is consistent across all definitions:
•
Specify
function. The compiler then generates the appropriate symbol table
information, including the index.
•
Use the
name with an index.
Since register
cannot return a value larger than four words. Refer to the i960 Processor
Software Utilities User's Guide for more information.
