-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_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.

-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.

-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.

-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] libiberty: fix --enable-install-libiberty flag [PR 56780]
-
-Commit 199570 fixed the --disable-install-libiberty behavior, but it also
-added a bug where the enable path never works because the initial clear
-of target_header_dir wasn't deleted. So we end up initializing properly
-at the top only to reset it at the end all the time.

-Subject: [PATCH] Fix library paths on PowerPC
-
-First, need to match against just the CPU name, not the whole triplet.
-Otherwise, the test picks up "*le-*" pattern from x86_64-apple-darwin
-triplet.
-
-Second, it should be testing for $target, not $host. Host may be
-little endian by default, and the sysroot directory layout shouldn't
-depend on whether it is built on LE or BE machine.

- 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.

-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.

-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.
-

-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.

-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.

-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.

-
-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.
-

-First, need to match against just the CPU name, not the whole triplet.
-Otherwise, the test picks up "*le-*" pattern from x86_64-apple-darwin
-triplet.
-
-Second, it should be testing for $target, not $host. Host may be
-little endian by default, and the sysroot directory layout shouldn't
-depend on whether it is built on LE or BE machine.

-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.

-find_removed_literal uses linear search to find removed literal by its
-VMA. The list of literals is fixed at that point, build an ordered index
-array and use binary search instead.

-
-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.

-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.

-
-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.

-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.

-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>
-gas/
- * config/tc-xtensa.c (xtensa_move_literals): Fix check for
- .init.literal/.fini.literal section name.
- * testsuite/gas/xtensa/all.exp: Add init-fini-literals to the

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

-Otherwise, the test picks up "*le-*" pattern from x86_64-apple-darwin

-Second, it should be testing for $target, not $host. Host may be

-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.
-

-First, need to match against just the CPU name, not the whole triplet.
-Otherwise, the test picks up "*le-*" pattern from x86_64-apple-darwin
-triplet.
-
-Second, it should be testing for $target, not $host. Host may be
-little endian by default, and the sysroot directory layout shouldn't
-depend on whether it is built on LE or BE machine.

-Subject: [PATCH] Fix library paths on PowerPC
-
-First, need to match against just the CPU name, not the whole triplet.
-Otherwise, the test picks up "*le-*" pattern from x86_64-apple-darwin
-triplet.
-
-Second, it should be testing for $target, not $host. Host may be
-little endian by default, and the sysroot directory layout shouldn't
-depend on whether it is built on LE or BE machine.
