Directive funcorg

You can use the #pragma funcorg directive to specify the starting address of a routine in ROM using routine name

only:

#pragma funcorg <func_name> <starting_address>

Indirect Function Calls

If the linker encounters an indirect function call (by a pointer to function), it assumes that any of the functions addresses

of which were taken anywhere in the program, can be called at that point. Use the #pragma funcall directive to instruct

the linker which functions can be called indirectly from the current function:

#pragma funcall <func_name> <called_func>[, <called_func>,...]

A corresponding pragma must be placed in the source module where the function func_name is implemented. This

module must also include declarations of all functions listed in the called_func list.

These functions will be linked if the function func_name is called in the code no matter whether any of them was called

or not.

Note : The #pragma funcall directive can help the linker to optimize function frame allocation in the compiled

stack.
