Dear Alan,

thanks for your response. Indeed, adding the flag -mregnames alowed to assemble the problematic section of code. (Although I don't understand why I don't need this flag when generating code for the 403). However I have experienced more problems, e.g. with the iccci and dccci instructions, which are as well defined for the 403 only, but not for the 440.

I know some projects (e.g. BlueGene, QCDOC) are using the 440 and the GNU tool chain. Therefore I assume there should be an updated version of the binutils existing somewhere ?

Thanks for your help.

Error: unsupported relocation against r9

I would guess that you need to assemble using -mregnames, or you need to
write either %r9 or plain 9 to mean gpr9.
