Hi,

I have found the problem with generation of dll on SGI IRIX 6.2.
The problem was located in generation of base file in ld, and not in dlltool
....
In bfd/cofflink.c we have this kind of code:

	bfd_vma addr = ...
	...
	fwrite (&addr, 1,4, (FILE *) info->base_file);

the problem is that on SGI a bfd_vma is a "long long" (size 64 bits), so only
the 4 first bytes (which are always 0) are written.

For fixing this bug we only have to cast addr in a 32 bits value. My problem is
that the type "uint32" doesn't exist anymore, so I used a cast to "long",
hoping that the size of "long" is always 32 bits (???????).
May be can somebody find a cleaner solution, in this case send me a mail.

You can find, attached to this mail, the corresponding diff file.

Best regards.
