#pragma reachable

Purpose

Informs the compiler that the point in the program after a named function can be the target of a branch from some unknown location.

By informing the compiler that the instruction after the specified function can be reached from a point in your program other than the return statement in the named function, the pragma allows for additional opportunities for optimization.

Note: The compiler automatically inserts #pragma reachable directives for the setjmp family of functions (setjmp, _setjmp, sigsetjmp, and _sigsetjmp) when you include the setjmp.h header file.

Syntax


                            .-,-------------.      
                            V               |      
>>-#--pragma--reachable--(----function_name-+--)---------------><

Parameters

function_name: The name of a function preceding the instruction which is reachable from a point in the program other than the function's return statement.
