Following the arrangement in GCC select a 64-bit ABI by default, either
n32 or n64, rather than o32 for `mipsisa64*-*-linux*' targets, just as
with the corresponding `mips64*-*-linux*' targets.
|
|
Use targ_size=64 and targ_extra_size=32
|
|
So we can enable 64bit ELF support for MIPS32 toolchain.
|
|
Only mips*el triples are supported by binutils. The mips*le
or mips*el* may cause some problem with other components of
binutils, since they will consider them as big endian.
|

EM_MIPS_RS3_LE has been deprecated quite long ago, and in fact
most of current LE ELF files are using EM_MIPS.
This problem didn't make some trouble for us, is due to that
gold is a linker, and all of the inputs to it has right EM values.
|
|
This option will be used by architectures which is big endian
by default, while little-endian support is also needed.
Mips(eb) ports are the examples.

Caused by commit 5a97377e5513, specifically this code added to
Target_powerpc::do_relax
+ if (parameters->options().output_is_position_independent())
+ this->rela_dyn_size_
+ = this->rela_dyn_section(layout)->current_data_size();
The problem here is that if .rela.dyn isn't already created then the
call to rela_dyn_section creates it, and as this comment in
Target_powerpc::do_finalize_sections says:
// Annoyingly, we need to make these sections now whether or
// not we need them. If we delay until do_relax then we
// need to mess with the relaxation machinery checkpointing.
We can't be creating sections in do_relax.

* powerpc.cc (Target_powerpc::do_relax): Only set rela_dyn_size_

PowerPC64 gold and ld.bfd implement an indirect branch trampoline,
used when the destination of a branch exceeds a bounce through another
"b" instruction. When generating PIEs or shared libraries, the
addresses need dynamic relocations. This was implemented in gold
using a dedicated relocation section, but this means the relative
relocations for these addresses are not sorted properly with other
dynamic relative relocations: gold doesn't support merging relocation
sections, then sorting. Instead we need to use a single .rela.dyn
section.
This is done by increasing the size of rela_dyn_ during do_relax to
account for needed dynamic relocations, delaying adding the actual
relocations until the end of relaxation once the layout has
stabilised.
* powerpc.cc (Target_powerpc): Add rela_dyn_size_;
(update_current_size): New function.
(Target_powerpc::do_relax): Capture the size of rela_dyn_ at

DT_RELACOUNT was calculated incorrectly, and relative relocs not
sorted as they should be to the start of .rela.dyn, due to adding one
particular class of dynamic reloc using the wrong "add" method.

In commit 0961e631575b, the fix for PR30217, make_lplt_section and
make_brlt_section were changed to use rela_dyn_ rather than their own
separate dynamic reloc sections. This fails miserably whenever brlt_
is needed for long branches, due to needing to iterate sizing and thus
reset brlt_ sizes.

Let's recognize them by `mips*64*(el)`.
For 64bit Ports, like Debian's mips64el and mips64r6el ports,

glibc's ld.so ignores local dynamic symbols. It's been that way
forever. We therefore can't use them on dynamic relocations. Fixing
that problem uncovered another problem in sorting of dynamic relocs,
caused no doubt by copying make_iplt_section (where we don't want
reloc sorting by the generic gold function, we want iplt relocs last)
to make_lplt_section (where we do want sorting).
