Target specific relocation ld integration.

[Dominique Torette <Dominique dot Torette at spacebel dot be>]

Hi,

I'm porting the GNU binutils to an' in-house' microcontroller.
I've followed the http://www.opensourceforu.com/2010/01/binutils-porting-guide-to-a-new-target-architecture/
It seems that the libbfd is quite complete. I can use most of binutils, except the . linker.
It works except the relocations. My input format is elf32.
I have only one simple relocation schema for 'jump' like instructions.
The format for these instructions are the opcode on 32 bits, followed by the absolute 32 bits address of the jump.
I have defined an 'elf32-myArch.c' file to define the reloc_map, reloc_howt_type, the reloc_type_lookup and the reloc_name_lookup.
I've tried to run the ld command under debugger and set breakpoint on my reloc_type_lookup and reloc_name_lookup functions.
But I never reach these breakpoints! I've tried a step-by-step execution, but I didn't seen where and how the target specific relocation functions are registered.
Could you give some additional hints to integrate my target specific relocation schema.

Thanks in advance, Dominique Torette.
