Example 2. Output Section for unordered() Operator

SECTIONS
{
  .text: unordered()
  {
    file.obj(.text:func_a)
    file.obj(.text:func_b)
    file.obj(.text:func_c)
    file.obj(.text:func_d)
    file.obj(.text:func_e)
    file.obj(.text:func_f)
    file.obj(.text:func_g)
    file.obj(.text:func_h)

    *(.text)
  } > PMEM
  ...
}

So that, given this list of --preferred_order options:

--preferred_order="func_g"
--preferred_order="func_b"
--preferred_order="func_d"
--preferred_order="func_a"
--preferred_order="func_c"
--preferred_order="func_f"
--preferred_order="func_h"
--preferred_order="func_e"

The placement of the functions in the .text output section is guided by this preferred function order list. This placement will be reflected in a linker generated map file, as follows:
