-Subject: [PATCH] Use ucontext_t not struct ucontext in linux-unwind.h files.
-
-Current glibc no longer gives the ucontext_t type the tag struct
-ucontext, to conform with POSIX namespace rules.  This requires
-various linux-unwind.h files in libgcc, that were previously using
-struct ucontext, to be fixed to use ucontext_t instead.  This is
-similar to the removal of the struct siginfo tag from siginfo_t some
-years ago.
-
-This patch changes those files to use ucontext_t instead.  As the
-standard name that should be unconditionally safe, so this is not
-restricted to architectures supported by glibc, or conditioned on the
-glibc version.
-
-Tested compilation together with current glibc with glibc's
-build-many-glibcs.py.

-
-The change that made xtensa backend go ICE looks completely unrelated,
-and indeed, the issue is caused by the side effect of
-compute_frame_size() function call hidden in the
-INITIAL_ELIMINATION_OFFSET macro. This call updates the value of the
-xtensa_current_frame_size static variable, used in "return" instruction
-predicate. Prior to the change the value of xtensa_current_frame_size was
-set to 0 after the end of epilogue generation, which enabled the "return"
-instruction for the CALL0 ABI, but after the change the additional
-INITIAL_ELIMINATION_OFFSET calls make xtensa_current_frame_size non-zero
-and "return" pattern unavailable.
-
-Get rid of the global xtensa_current_frame_size and
-xtensa_callee_save_size variables by moving them into the
-machine_function structure. Implement predicate for the "return" pattern
-as a function. Don't communicate completion of epilogue generation
-through zeroing of xtensa_current_frame_size, add explicit epilogue_done
-variable to the machine_function structure. Don't update stack frame
-layout after the completion of reload.

-Subject: [PATCH] Use ucontext_t not struct ucontext in linux-unwind.h files.
-
-Current glibc no longer gives the ucontext_t type the tag struct
-ucontext, to conform with POSIX namespace rules.  This requires
-various linux-unwind.h files in libgcc, that were previously using
-struct ucontext, to be fixed to use ucontext_t instead.  This is
-similar to the removal of the struct siginfo tag from siginfo_t some
-years ago.
-
-This patch changes those files to use ucontext_t instead.  As the
-standard name that should be unconditionally safe, so this is not
-restricted to architectures supported by glibc, or conditioned on the
-glibc version.
-
-Tested compilation together with current glibc with glibc's
-build-many-glibcs.py.

-Subject: [PATCH] gcc: xtensa: fix fprintf format specifiers
-
-HOST_WIDE_INT may not be long as assumed in print_operand and
-xtensa_emit_call. Use HOST_WIDE_INT_PRINT_DEC/HOST_WIDE_INT_PRINT_HEX
-format strings instead of %ld/0x%lx. This fixes incorrect assembly code
-generation by the compiler running on armhf host.
-
-2017-05-28  Max Filippov  <jcmvbkbc@gmail.com>
-gcc/
-	* config/xtensa/xtensa.c (xtensa_emit_call): Use
-	HOST_WIDE_INT_PRINT_HEX instead of 0x%lx format string.
-	(print_operand): Use HOST_WIDE_INT_PRINT_DEC instead of %ld
-	format string.
