binutils: remove 2.20.1, 2.21 and 2.23.1 

- The 2.20.x series is old, it no longer makes sense to support it.

 - In the 2.21.x series, we still have 2.21.1, so keeping 2.21 doesn't
   make much sense, so this patch removes it.

 - Similarly for the 2.23.x series, having both 2.23.1 and 2.23.2
   doesn't make much sense, so this patch removes 2.23.1 and keeps
   2.23.2.

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 a82c7d9030b67a6a76a5403d0e1641f9e42141ac Mon Sep 17 00:00:00 2001
From: David Weatherford <weath@cadence.com>
Date: Fri, 21 Mar 2014 11:53:42 +0000
Subject: [PATCH] Add support to the Xtensa target for creating trampolines for
out-of-range branches.
* tc-xtensa.c (xtensa_check_frag_count, xtensa_create_trampoline_frag)
(xtensa_maybe_create_trampoline_frag, init_trampoline_frag)
(find_trampoline_seg, search_trampolines, get_best_trampoline)
(check_and_update_trampolines, add_jump_to_trampoline)
(dump_trampolines): New function.
(md_parse_option): Add cases for --[no-]trampolines options.
(md_assemble, finish_vinsn, xtensa_end): Add call to
xtensa_check_frag_count.
(xg_assemble_vliw_tokens): Add call to
xtensa_maybe_create_trampoline_frag.
(xtensa_relax_frag): Relax fragments with RELAX_TRAMPOLINE state.
(relax_frag_immed): Relax jump instructions that cannot reach its
target.
* tc-xtensa.h (xtensa_relax_statesE::RELAX_TRAMPOLINE): New relax
state.
* as.texinfo: Document --[no-]trampolines command-line options.
* c-xtensa.texi: Document trampolines relaxation and command line
options.
* frags.c (get_frag_count, clear_frag_count): New function.
(frag_alloc): Increment totalfrags counter.
* frags.h (get_frag_count, clear_frag_count): New function.
* all.exp: Add test for trampoline relaxation.
* trampoline.d: Trampoline relaxation expected dump.
* trampoline.s: Trampoline relaxation test source.

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.
