binutils: remove support for version 2.23 

Now that we have added support for the lastest binutils version 2.26,
it is time to remove the oldest version we currently support, 2.23, in
order to keep only 3 versions: 2.24, 2.25 and 2.26.

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).

From a35d5e823fdfe8a6e7e05ca8e3fb8bb5697335b1 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix alignment for the first section frag on xtensa
Linking object files produced by partial linking with link-time
relaxation enabled sometimes fails with the following error message:
dangerous relocation: call8: misaligned call target: (.text.unlikely+0x63)
This happens because no basic block with an XTENSA_PROP_ALIGN flag in the
property table is generated for the first basic block, even if the
.align directive is present.
It was believed that the first frag alignment could be derived from the
section alignment, but this was not implemented for the partial linking
case: after partial linking first frag of a section may become not
first, but no additional alignment frag is inserted before it.
Basic block for such frag may be merged with previous basic block into
extended basic block during relaxation pass losing its alignment
restrictions.
Fix this by always recording alignment for the first section frag.
2014-04-22 Max Filippov <jcmvbkbc@gmail.com>
gas/
* config/tc-xtensa.c (xtensa_handle_align): record alignment for the
first section frag.

Subject: [PATCH] Fix xtensa ld segfault when linking linux modules
is_inconsistent_linkonce_section makes an assumption that section name
that starts with ".gnu.linkonce.prop." has one more dot in its suffix.
However gas generates such section name by insertion of "prop." right
after ".gnu.linkonce." part of the name of the original section. So, for
section named ".gnu.linkonce.this_module" corresponding property section
name does not satisfy the assumption. Such section names are common in
linux modules. This bug was exposed by the patch "a35d5e8 Fix alignment
for the first section frag on xtensa", that makes gas produce property
section for each section that has ".align" directive in it.
Use suffix that immediately follows ".gnu.linkonce.prop." when there are
no more dots following it.

During link-time relaxation distance between cross-section call site and
its target may grow, producing 'call target out of range' error for
relaxed calls. Be more conservative when calculating whether or not a
callx can be converted to a straight call.

Subject: [PATCH] Fix trampolines search code for conditional branches
For conditional branches that need more than one trampoline to reach its
target assembler couldn't always find suitable trampoline because
post-loop condition check was placed inside the loop, resulting in
premature loop termination. Move check outside the loop.
This fixes the following build errors seen when assembling huge files
produced by gcc:
Error: jump target out of range; no usable trampoline found
Error: operand 1 of 'j' has out of range value '307307'

Subject: [PATCH] xtensa: fix localized symbol refcounting with --gc-sections

BFD (GNU Binutils) 2.24 internal error, aborting at elf32-xtensa.c line
3372 in elf_xtensa_finish_dynamic_sections
elf_xtensa_gc_sweep_hook determines symbol reference type (PLT or GOT) by
relocation type. Relocation types are not changed when symbol becomes
local, but its PLT references are added to GOT references and
plt.refcount is set to 0. Such symbol cannot be unreferences in the
elf_xtensa_gc_sweep_hook and its extra references make calculated GOT
relocations section size not match number of GOT relocations.
Fix it by treating PLT reference as GOT reference when plt.refcount is
not positive.

Subject: [PATCH] xtensa: fix .init/.fini literals moving
Despite the documentation and the comment in xtensa_move_literals, in
the presence of --text-section-literals and --auto-litpools literals are
moved from the separate literal sections into .init and .fini, because
the check in the xtensa_move_literals is incorrect.
This moving was broken with introduction of auto litpools: some literals
now may be lost. This happens because literal frags emitted from .init
and .fini are not closed when new .literal_position marks new literal
pool. Then frag_align(2, 0, 0) changes type of the last literal frag to
rs_align. rs_align frags are skipped in the xtensa_move_literals. As a
result fixups against such literals are not moved out of .init.literal/
.fini.literal sections producing the following assembler error:
test.S: Warning: fixes not all moved from .init.literal
test.S: Internal error!
Fix check for .init.literal/.fini.literal in the xtensa_move_literals
and don't let it move literals from there in the presence of
--text-section-literals or --auto-litpools.
