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.

ucontext_t instead of struct ucontext.

Subject: [PATCH] xtensa: don't use unwind-dw2-fde-dip with elf targets
Define LIB2ADDEH_XTENSA_UNWIND_DW2_FDE to unwind-dw2-fde.c in
xtensa/t-elf and to unwind-dw2-fde-dip.c in xtensa/t-linux and use
LIB2ADDEH_XTENSA_UNWIND_DW2_FDE in LIB2ADDEH definition.
This fixes build for elf target with windowed xtensa core that currently
breaks with the following error message:
unwind-dw2-fde-dip.c:36:40: fatal error: elf.h: No such file or directory

definition.
* config/xtensa/t-windowed (LIB2ADDEH): Use

Subject: [PATCH] xtensa: Fix PR target/78118
It started failing after the following commit: 32e90dc6a0cda45 ("PR
rtl-optimization/61047").
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] 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.

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.

From 06689e5973647f5c65d1984b164f2531f5418d7a Mon Sep 17 00:00:00 2001
From: Max Filippov <jcmvbkbc@gmail.com>
Date: Sun, 28 May 2017 19:56:56 -0700
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.
