I'm not knowledgeable about x86 but I don't believe it has a relocation equivalent to the PLABEL32 reloc. Everything in .rel.dyn may be relative.

The exceptions that I see are mips and score. Doing this will increase link time, so I tend to think it should be avoided if possible.

No. I was just thinking of trying to link the dynamic loader with this option. Didn't noticeThe dynamic loader is a special case, but there are some requirements.Have you tried the ld "-z combreloc" option to see if that works? It combines reloc sections and sorts them.I haven't tried that yet, are you saying we should change binutils to *default* to "-z combreloc?"
any other targets making it the default. Dave -- John David Anglin dave.anglin@xxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-parisc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
