What is your current gcc/as line? Do you have a cross compiler tool chain?
We just use -mcpu=403 and that also works for 405 (iccci, dccci).

Question on effort to port Diab Tools developed Power PC 405 assembly source to GNU

Hi,

We are trying to compile with gcc assembler some Power PC 405 test code that was developed with the Diab toolset and are getting various errors in an assembly test module.  There are problems with certain machine instructions not being  recognized (for example, iccci, dccci, mticcr, mtdccr),  and with certain style comments (semi-colon followed by dashes) resulting in mis-parsing of subsequent (semi-colon word word) style comments (with attempts to parse 'word' as an assembly instruction).

Is there a gcc assembler switch of some kind to allow for PPC405 differences?

Thanks,
David Goble
