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] xtensa: fix memory corruption by broken sysregs
In some xtensa configurations there may be system/user registers in
xtensa-modules with negative index. ISA initialization for such config
may clobber heap and result in program termination.
Don't update lookup table entries for register with negative indices.
They are not directly accessible via RSR/WSR/XSR or RUR/WUR, so this
change should not affect processing of valid assembly/binary code.

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 1/4] xtensa: optimize check_section_ebb_pcrels_fit
The original check_section_ebb_pcrels_fit algorithm checks that text
actions proposed for current EBB are OK for every relocation in a
section. There's no need to check every relocation, because text actions
for EBB can only change size of that EBB, thus only affecting
relocations that in any way cross that EBB. In addition EBBs are
iterated in ascending order of their VMA, making it easier to track
relevant relocations.
Introduce a structure that can track relocations that cross the range of
VMAs of EBB and use it to only check relocations relevant to current EBB
in check_section_ebb_pcrels_fit.
It takes O(N log N) operations to build it and O(N) operations to move
current EBB VMA window through its entire range, where N is the number
of relocations in a section. The resulting complexity of
compute_text_actions is thus reduced from O(N^2) to O(N log N + N * M),
where M is the average number of relocations crossing each EBB.

Subject: [PATCH 2/4] xtensa: optimize removed_by_actions
The function removed_by_actions iterates through text actions to
calculate an offset applied by text actions to a given VMA. Although it
has a parameter p_start_action that allows for incremental offset
calculation, in many places it's used with p_start_action explicitly set
to the first action. After the first relaxation pass when the list of
text actions is finalized, an array of offsets sorted by VMA may be used
to speed up this function.

Subject: [PATCH 4/4] xtensa: replace action list with splay tree
text_action_add uses linear list search to order text actions list by
action VMA. The list is used at the first relaxation pass, when it's not
fixed yet.
Replace the list with splay tree from libiberty.

2015-04-03 Max Filippov <jcmvbkbc@gmail.com>
bfd/
* elf32-xtensa.c (splay-tree.h): include header.
(text_action_struct): drop next pointer.
(text_action_list_struct): drop head pointer, add count and
tree fields.
(find_fill_action): instead of linear search in text_action_list
search in the tree.
(text_action_compare, action_first, action_next): new functions.
(text_action_add, text_action_add_literal): instead of linear
search and insertion insert new node into the tree.
(removed_by_actions): pass additional parameter: action_list,
use it to traverse the tree.
(offset_with_removed_text): pass additional action_list parameter
to removed_by_actions.
(map_action_fn_context): new typedef.
(map_action_fn_context_struct): new structure.
(map_action_fn): new function.
(map_removal_by_action): use splay_tree_foreach to build map.
(find_insn_action): replace linear search in text_action_list
with series of splay_tree_lookups.
(print_action, print_action_list_fn): new functions.
(print_action_list): use splay_tree_foreach.
(init_xtensa_relax_info): drop action_list.head initialization.
Initialize the tree.
(compute_text_actions): use non-zero action_list_count instead of
non-NULL action list.
(xlate_map_context): new typedef.
(xlate_map_context_struct): new structure.
(xlate_map_fn): new function.
(build_xlate_map): use splay_tree_foreach to build map.
(action_remove_bytes_fn): new function.
(relax_section): use zero action_list_count instead of NULL
action list. Use splay_tree_foreach to count final section size.
Drop unused variable 'removed'.

Subject: [PATCH] xtensa: optimize trampolines relaxation
Currently every fixup in the current segment is checked when relaxing
trampoline frag. This is very expensive. Make a searchable array of
fixups pointing at potentially oversized jumps at the beginning of every
relaxation pass and only check subset of this cache in the reach of
single jump from the trampoline frag currently being relaxed.

Subject: [PATCH] xtensa: fix localized symbol refcounting with --gc-sections
elf_xtensa_gc_sweep_hook doesn't correctly unreference symbols that were
made local, that results in link failure with the following message:
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: add --auto-litpools option
Auto-litpools is the automated version of text-section-literals: literal
pool candidate frags are planted every N frags and during relaxation
they are turned into actual literal pools where literals are moved to
become reachable for their first reference by L32R instruction.
2015-08-12 David Weatherford <weath@cadence.com>
gas/
* config/tc-xtensa.c (struct litpool_frag, struct litpool_seg):
New structures.
(xtensa_maybe_create_literal_pool_frag): New function.
(litpool_seg_list, auto_litpools, auto_litpool_limit)
(litpool_buf, litpool_slotbuf): New static variables.
(option_auto_litpools, option_no_auto_litpools)
(option_auto_litpool_limit): New enum identifiers.
(md_longopts): Add entries for auto-litpools, no-auto-litpools
and auto-litpool-limit.
(md_parse_option): Handle option_auto_litpools,
option_no_auto_litpools and option_auto_litpool_limit.
(md_show_usage): Add help for --[no-]auto-litpools and
--auto-litpool-limit.
(xtensa_mark_literal_pool_location): Record a place for literal
pool with a call to xtensa_maybe_create_literal_pool_frag.
(get_literal_pool_location): Find highest priority literal pool
or convert candidate to literal pool when auto-litpools are used.
(xg_assemble_vliw_tokens): Create literal pool after jump
instruction.
(xtensa_check_frag_count): Create candidate literal pool every
auto_litpool_limit frags.
(xtensa_relax_frag): Add jump around literals to non-empty
literal pool.
(xtensa_move_literals): Estimate literal pool addresses and move
unreachable literals closer to their users, converting candidate
to literal pool if needed.
(xtensa_switch_to_non_abs_literal_fragment): Only emit error
about missing .literal_position in case auto-litpools are not
used.
* config/tc-xtensa.h (xtensa_relax_statesE): New relaxation
state: RELAX_LITERAL_POOL_CANDIDATE_BEGIN.
2015-08-12 Max Filippov <jcmvbkbc@gmail.com>
gas/testsuite/
* gas/xtensa/all.exp: Add auto-litpools to the list of xtensa
tests.
* gas/xtensa/auto-litpools.s: New file: auto-litpools test.
* gas/xtensa/auto-litpools.s: New file: auto-litpools test
result pattern.

Subject: [PATCH] xtensa: fix signedness of gas relocations
Change 1058c7532d0b "Use signed data type for R_XTENSA_DIFF* relocation
offsets." changed signedness of BFD_RELOC_XTENSA_DIFF* relocations
substituted for BFD_RELOC_*. This made it impossible to encode arbitrary
8-, 16- and 32-bit values, which broke e.g. debug info encoding by .loc
directive. Revert this part and add test.

substitutions for BFD_RELOC_* as unsigned.

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.

Subject: [PATCH] xtensa: fix signedness of gas relocations
Change 1058c7532d0b "Use signed data type for R_XTENSA_DIFF* relocation
offsets." changed signedness of BFD_RELOC_XTENSA_DIFF* relocations
substituted for BFD_RELOC_*. This made it impossible to encode arbitrary
8-, 16- and 32-bit values, which broke e.g. debug info encoding by .loc
directive. Revert this part and add test.

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.
2016-02-17 Max Filippov <jcmvbkbc@gmail.com>

* config/tc-xtensa.c (xtensa_move_literals): Fix check for
.init.literal/.fini.literal section name.

* testsuite/gas/xtensa/init-fini-literals.d: New file:

From fdb0d1d63d8dc30b319db174f2a90e681d8cd2ed Mon Sep 17 00:00:00 2001
From: Romain Naour <romain.naour@gmail.com>
Date: Fri, 25 Dec 2015 11:38:13 +0100
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).
[Romain: rebase on top of 2.26]
Signed-off-by: Romain Naour <romain.naour@gmail.com>
[Thomas: rebase on top of 2.29, in which sh64 support was removed.]

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).
