-
-On glibc the libc.so carries a copy of the math function copysignl() but
-on uClibc math functions like copysignl() live in libm. Since libgcc_s
-contains unresolved symbols, any attempt to link against libgcc_s
-without explicitely specifying -lm fails, resulting in a broken
-bootstrap of the compiler.
-
-Forward ported to gcc 4.7.3

-Commit 199570 fixed the --disable-install-libiberty behavior, but it also

-Add musl support to gcc
-
-This patch comes from the musl-cross project at
-https://bitbucket.org/GregorR/musl-cross/src. Compared to the upstream version:
-
- * the config.sub modifications have been removed, because Buildroot
-   already overwrites all config.sub with a more recent config.sub
-   that has musl support.
-
- * change to ensure that a dummy dynamic linker path
-   MUSL_DYNAMIC_LINKER<foo> is defined for all architectures,
-   otherwise building gcc for architectures not supported by musl was
-   causing build failure. Bug reported upstream at
-   https://bitbucket.org/GregorR/musl-gcc-patches/issue/4/musl-gcc-patches-break-the-build-on.
-
- * change the USE_PT_GNU_EH_FRAME logic to keep the existing gcc logic
-   and only add the musl one as an addition, not as a replacement. Not
-   doing this breaks C++ exception handling with glibc, because
-   USE_PT_GNU_EH_FRAME doesn't get defined due to the configure script
-   not testing dl_iterate_phdr() on any system except Solaris.

+Subject: [PATCH 1/2] 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.
+
+2016-10-26  Max Filippov  <jcmvbkbc@gmail.com>
+gcc/
+	* config/xtensa/xtensa-protos.h
+	(xtensa_use_return_instruction_p): New prototype.
+	* config/xtensa/xtensa.c (xtensa_current_frame_size,
+	xtensa_callee_save_size): Remove.
+	(struct machine_function): Add new fields: current_frame_size,
+	callee_save_size, frame_laid_out and epilogue_done.
+	(compute_frame_size, xtensa_expand_prologue,
+	xtensa_expand_epilogue): Replace xtensa_callee_save_size with
+	cfun->machine->callee_save_size and xtensa_current_frame_size
+	with cfun->machine->current_frame_size.
+	(compute_frame_size): Update cfun->machine->frame_laid_out and
+	don't update frame layout after reload completion.
+	(xtensa_expand_epilogue): Set cfun->machine->epilogue_done
+	instead of zeroing xtensa_current_frame_size.
+	(xtensa_use_return_instruction_p): New function.
+	* config/xtensa/xtensa.h (xtensa_current_frame_size): Remove
+	declaration.
+	(INITIAL_ELIMINATION_OFFSET): Use return value of
+	compute_frame_size instead of xtensa_current_frame_size value.
+	* config/xtensa/xtensa.md ("return" pattern): Use new predicate
+	function xtensa_use_return_instruction_p instead of inline code.

+[PATCH] cilk: fix build without wchar
+
+When building against uClibc with wchar support disabled, WCHAR_MIN and
+WCHAR_MAX are not defined leading to compilation errors.
+
+Fix it by only including the wchar code if available.
