From f88f4c77266b9669b285ab64386cf39e183661bb Mon Sep 17 00:00:00 2001

Subject: [PATCH] sh-conf
Likewise, binutils has no idea about any of these new targets either, so we
fix that up too.. now we're able to actually build a real toolchain for
sh2a_nofpu- and other more ineptly named toolchains (and yes, there are more
inept targets than that one, really. Go look, I promise).

Subject: [PATCH] or1k: Fix issue with plt link failure for local calls
When building protobuf we were seeing the assert failure:

BFD (GNU Binutils) 2.36.1 assertion fail elf32-or1k.c:2377
collect2: error: ld returned 1 exit status
This failure happens while writing out PLT entries, there is a check
"BFD_ASSERT (h->dynindx != -1)" to confirm all plt entries have dynamic
symbol attributes. This was failing for symbols that were
"forced_local" in previous linking code.
The fix adds logic to or1k_elf_adjust_dynamic_symbol to identify
"forced_local" symbols and exclude them from the the PLT.

Subject: [PATCH] or1k: Implement relocation R_OR1K_GOT_AHI16 for gotha()
The gotha() relocation mnemonic will be outputted by OpenRISC GCC when
using the -mcmodel=large option. This relocation is used along with
got() to generate 32-bit GOT offsets. This increases the previous GOT
offset limit from the previous 16-bit (64K) limit.
This is needed on large binaries where the GOT grows larger than 64k.

Subject: [PATCH] or1k: Avoid R_OR1K_GOT16 overflow failures in presence of
R_OR1K_GOT_AHI16
Now that we support R_OR1K_GOT_AHI16 we can relax the R_OR1K_GOT16
overflow validation check if the section has R_OR1K_GOT_AHI16.
We cannot simple disable R_OR1K_GOT16 overflow validation as there will
still be binaries that will have only R_OR1K_GOT16. The
R_OR1K_GOT_AHI16 relocation will only be added by GCC when building with
the option -mcmodel=large.
This assumes that R_OR1K_GOT_AHI16 will come before R_OR1K_GOT16, which
is the code pattern that will be emitted by GCC.
bfd/ChangeLog:
PR 21464
* elf32-or1k.c (or1k_elf_relocate_section): Relax R_OR1K_GOT16
overflow check if we have R_OR1K_GOT_AHI16 followed by
R_OR1K_GOT16.

Subject: [PATCH] or1k: Support large plt_relocs when generating plt
entries
The current PLT generation code will generate invalid code when the PLT
relocation offset exceeds 64k. This fixes the issue by detecting large
plt_reloc offsets and generare code sequences to create larger plt
relocations.
The "large" plt code needs 2 extra instructions to create 32-bit offsets.
bfd/ChangeLog:
PR 27746
* elf32-or1k.c (PLT_ENTRY_SIZE_LARGE, PLT_MAX_INSN_COUNT,
OR1K_ADD, OR1K_ORI): New macros to help with plt creation.

Subject: [PATCH] bfd/elf32-or1k: fix building with gcc version < 5
Gcc version >= 5 has standard C mode not set to -std=gnu11, so if we use
an old compiler(i.e. gcc 4.9) build fails on:
```
elf32-or1k.c:2251:3: error: 'for' loop initial declarations are only allowed in
C99 or C11 mode
for (size_t i = 0; i < insn_count; i++)
^
```
So let's declare `size_t i` at the top of the function instead of inside
for loop.

Subject: [PATCH] or1k: fix pc-relative relocation against dynamic on PC
relative 26 bit relocation
When building openal we were seeing the assert failure:

pc-relative relocation against dynamic symbol alSourcePlayv
collect2: error: ld returned 1 exit status
This happens because in R_OR1K_INSN_REL_26 case we can't reference local
symbol as previously done but we need to make sure that calls to actual
symbol always call the version of current object.
bfd/Changelog:
* elf32-or1k.c (or1k_elf_relocate_section): use a separate entry
in switch case R_OR1K_INSN_REL_26 where we need to check for
!SYMBOL_CALLS_LOCAL() instead of !SYMBOL_REFERENCES_LOCAL().

Subject: [PATCH] or1k: Avoid R_OR1K_GOT16 signed overflow by using special
howto
Previously when fixing PR 21464 we masked out upper bits of the
relocation value in order to avoid overflow complaints when acceptable.
It turns out this does not work when the relocation value ends up being
signed.
To fix this this patch introduces a special howto with
complain_on_overflow set to complain_overflow_dont. This is used in
place of the normal R_OR1K_GOT16 howto when we detect R_OR1K_GOT_AHI16
relocations.
bfd/ChangeLog:
PR 28735
* elf32-or1k.c (or1k_elf_got16_no_overflow_howto): Define.
(or1k_elf_relocate_section): Use new howto instead of trying to
mask out relocation bits.
