PPC assembler problem

- Subject: PPC assembler problem
Hello,
I am using a cross GCC 4.5.0 configured for a PPC-ELF target. The
compiler generates code like this:
-- snip --
lis 0,symbol+520@ha
addic 4,0,symbol@l+520
-- snip --
FWIW, GCC 4.4 generates similar code for the same source file. GAS
(a very old one, but that shouldn't matter) assembles this without
a complaint. Using a non-GNU assembler yields in an error for the
addic instruction. That assembler doesn't like the addition _after_
the @l reloc. In the lis instruction the addition is emitted before
the reloc. Is the placement of the addition after the @l reloc a GCC
bug and GAS is simply to lenient?
Regards,
Gunther Nikl
