--- Comment #5 from Peter Smith <peter.smith at linaro dot org> ---
I think that the new error message for R_AARCH64_ABS32 from the linker makes
some sense if the destination symbol is section relative as there is no dynamic
relocation supported and truncating a 64-bit address is most likely a mistake.
However if the destination symbol is absolute the linker shouldn't make the
assumption that the symbol is an address so it should resolve the relocation at
static link-time.
I think the test:
case BFD_RELOC_AARCH64_16:
#if ARCH_SIZE == 64
case BFD_RELOC_AARCH64_32:
#endif
if (bfd_link_pic (info)
&& (sec->flags & SEC_ALLOC) != 0
&& (sec->flags & SEC_READONLY) != 0)
... Give error message
Should check that the symbol is not absolute as well.
Unfortunately I can't think of a workaround for the case where the value of the
symbols has to be in the RO-segment. For some reason the check only applies in
RO sections, which does not make a lot of sense to me as a R_AARCH64_ABS32 from
a RW section to an address will truncate it in the same way as if it were from
a RO section. No dynamic relocation is generated for either RO or RW so I don't
know why the distinction has been made.
