Re: PATCH: support for NEC SX architecture


You'd better to submit your patches inline (not as a tar.gz) as it is
easier to review.
well, the patches are quite big, so I though it would be nicer to pack
them - didnt really expect someone would review them in their email
client ... I can resubmit them inline, if necessary.

One usual way is to split the patch (as you did) and post part by part.


It is strange to use bfd_vma type for f_nsyms in include/coff/ internal.h
true. however, I needed a type with the same domain as the virtual
addresses of the target CPU: any suggestions?

Requiring the same domain is too strong here. You can have 32bits targets even when
bfd_vma is 64bits. If you need a domain larger or equal than virtual addresses domain,
bfd_vma will fit this purpose although you may prefer bfd_size_type.


Why are you using SX_PACKED in declaration of external_filhdr,
external_aouthdr ... ?
just to make sure that the compiler does not introduce any padding as
these structures should correspond to the memory/file contents of an SX
COFF file, bit by bit. it's an sx target specific define that translates
to gcc packed attribute. I tend to abstract gccisms away with defines
whenever possible.

All the structures (but external_syment) have only char[] fields. external_syment has a char * field
but within a union with at least a larger field. So padding won't be inserted and I think this is not
necessary.
Using a gcc specific attribute may break other compilers (but I agree this is not critical).


Although I am ready to read your patch (when inlined), I can't approve
it.
I thought so, it was more a question for Nick or anybody else who can
say yes to some of the changes in the core coff code - it's those that
probably need review most, not the target specific code.

Fine!


BTW: in there a documentation for the cpu ?
sure there is. ;) it is unfortunately not (or, better, is not supposed
to be) publicly available. however, asking google about it, you just
might find something. ;)

Thanks,


Tristan.
