RE: Output sections

["Robles Román, José Miguel" <jmrroman at indra dot es>]

Hello,

You may use a command script for linking (ld -T <script_file>) with something similar to:
SECTIONS
{
.text1: 
  {
   file1 (.text)
   file2 (.text)
  }
.text2
  {
   file3 (.text)
   file4 (.text)
  }
}

In this example you are going to put in the section .text1 the sections .text of 
object files file1 and file2, and in the section .text2, the sections .text of
file3 and file4 (In sections .text, gcc put code and constants, in .data initialized
data, in .bss uninitialized data, ...).

In http://www.gnu.org/manual/ld-2.9.1/ld.html you can see the document 
"Using LD - the GNU Linker", where you will find much more valuable information.

Asunto: Output sections


I want to change the section all the functions in a file are put into.
For example, instead of putting them in 'text', I want them all in
'cpu1_text'.

I know I can use the __attribute__ modifier, but I'm hoping there's a
way to do it on and entire file at once.

The reason is I have a CPU with multiple cores, and some files have
functions that need to be in a core's local memory rather than the
shared text section.

Thanks for the help.
