B.1 Example 1

This example shows how to use the following pseudo-ops to specify the bindings of variables in C:

common, .global, .local, .weak

The following C definitions/declarations:

    int            foo1 = 1;
    #pragma                weak foo2 = foo1
    static            int foo3;
    static            int foo4 = 2;

can be translated into the following assembly code.

Example B-1 Using Pseudo-ops to Specify C Variable Bindings

    .pushsection    ".data"

    .global    foo1    ! int foo1 = 1
    .align    4
foo1:
    .word    0x1
    .type        foo1,#object                ! foo1 is of type data object,
    .size        foo1,4                ! with size = 4 bytes
       
    .weak            foo2            ! #pragma weak foo2 = foo1
    foo2 = foo1

    .local            foo3            ! static int foo3
    .common            foo3,4,4

    .align            4            ! static int foo4 = 2
   foo4:
    .word            0x2
    .type            foo4,#object
    .size            foo4,4

    .popsection
