+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.

+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.

+
+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'
+

+gas/
+	* config/tc-xtensa.c (search_trampolines): Move post-loop
+	condition check outside the search loop.
+
+gas/testsuite/
+	* gas/xtensa/trampoline.d: Add expected output for branches.
+	* gas/xtensa/trampoline.s: Add test case for branches.

+
+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.
