Re: Bug report on GNU linker for ARC processor

[Nick Clifton]

Hi Lucas,

>    I've tried the patch, but failed to work.

That is strange.  I tried assembling the main.s file that you
attached, linking with LinkCmd script you supplied and using the
command line from the Makefile and everything worked!  Here is part of
the objdump of the resulting a.out file:

009000f0 <x0>:
  9000f0:       00 20 7f 08     087f2000     lr         r3,[0xffed_0001]
  9000f4:       01 00 ed ff 
  9000f8:       ff ff ff 7f     7fffffff     nop

  900100:       ff ff ff 7f     7fffffff     nop

  90011c:       ff ff ff 7f     7fffffff     nop        
  900120:       ff ff ff 7f     7fffffff     nop        


The branch to _etmain does appear to have been correctly computed.

Did you rebuild the BFD library and then the linker after applying the
patch that I sent ?  Do you install the rebuilt linker ?

I would prefer not to do this.  I am working on your problem in my
spare time, so I am doing this as a service to the net community.  If
you would like to have official support and technical help for the
ARC toolchain, please feel free to contact Red Hat or any other GNU
software specialist company.  I am sure that they would be happy to
sell you their services.

Cheers
