Question about the function "find_pc_sect_partial_function"


Dear all:

        I have meet a problem and try to solve it for about two days, but 
it's still there, so wish you help me.

        my gdb version is 6.1.1

        suppose the following program :

         .section .text
        .proc   main
        .global main
         main:
        .BB1_main:   <-- 0x80000100
         ... ...
        ... ...
         .BB2_main:  <-- 0x80000200 
        ... ...
        ... ...

        if I call find_pc_partial_function (0x80000201, &name,&start,&end)
       the name will be .BB2_main and the value of start is 0x80000200 (Is 
this right?)

        then I call find_pc_partial_function (0x80000199, 
&name,&start,&end)
        the name will be main and the value of start is 0x80000100

        if I call find_pc_partial_function (0x80000201, &name,&start,&end) 
again,
        the name will be main and the value of start is 0x80000100. (why?)

        Why in the first step it just gets a label ?
