Question

Suppose i have two functions in x86 assembly language defined as :

.globl func_name1;      
.type func_name1, @function;
.align 2;
 func_name1:
 //Some assembly instructions here.

and similarly second function:

.globl func_name2;      
.type func_name2, @function;
.align 2;
 func_name2:
 //Some assembly instructions here.

Now what is the meaning of the following-

.data
.globl var_temp
 var_temp:
   .long func_name1
   .long func_name2

Thanks in advance !

Answer 1

Those .long’s define pointers to functions. var_temp looks like an array of 2 pointers to functions.
