Re: [arm-gnu] Linker section mapping difference between ARM RVCT and CodeSoucery toolchain

Assuming that:

  A. The arm-none-eabi linker is based on a sufficiently recent version 
of the binutils sources and...
  B. You do not mind if the sections are placed in a section next to 
the .text section in the output file, (rather then actually inside the 
.text section) then...
You can use the INSERT linker script directive along with the -T linker 
command line switch to achieve what you want.  eg:
  % cat rcvt.inline.linker_script
  SECTIONS
  {
    .text.i{ *(i.*) }
  }
  INSERT BEFORE .text;

  % arm-none-eabi-gcc -Wl,-T,rcvt.inline.linker_script 
<rest-of-gcc-command-line>

An alternative approach is to use the objcopy program to rename the i.* 
sections.  You would have to create a script to scan an object file, 
extract the names of all of the i.* sections, convert these names into 
"--rename-section <old>=<new>" command line options and then run objcopy 
 with these options.
Cheers
