The pseudo-ops shown in this example are .align, .global, .type, and .size.

The following C subroutine:

int sum(a, b)
    int a, b;
    return(a + b);

can be translated into the following assembly code:

    .section            ".text"

    .global            sum

    .align            4


    add        %o0,%o1,%o0                ! (a + b) is done in the

    .type        sum,#function                ! sum is of type function

                            ! of current location
