Example 5. The SECTIONS Directive

{
   .text:       load = EXT_MEM, run = 0x00000800
   .const:      load = FAST_MEM
   .bss:        load = SLOW_MEM
   .vectors:    load = 0x00000000
      {
         t1.c.obj(.intvec1)
         t2.c.obj(.intvec2)
         endvec = .;
      }
   .data:alpha: align = 16
   .data:beta:  align = 16
}

Figure 12-2 shows the output sections defined by the SECTIONS directive in Example 5 (.vectors, .text, .const, .bss, .data:alpha, and .data:beta) and shows how these sections are allocated in memory using the MEMORY directive given in Example 3.
