-Allow C99-depending features of libstdc++ with uClibc
-
-The libstdc++ code is fairly restrictive on how it checks for C99
-compatibility: it requires *complete* C99 support to enable certain
-features. For example, uClibc provides a good number of C99 features,
-but not C99 complex number support. For this reason, libstdc++
-completely disables many the standard C++ methods that can in fact
-work because uClibc provides the necessary functions.
-
-This patch is similar and highly inspired from
-https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58393, but implemented in
-a way that doesn't involve changing the configure.ac script, as
-autoreconfiguring gcc is complicated. It simply relies on the fact
-that uClibc defines the __UCLIBC__ definition.

-[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.

-Subject: [PATCH] xtensa: add -mauto-litpools option
-
-With support from assembler this option allows compiling huge functions,
-where single literal pool at the beginning of a function may not be
-reachable by L32R instructions at its end.
-
-Currently assembler --auto-litpools option cannot deal with literals
-used from multiple locations separated by more than 256 KBytes of code.
-Don't turn constants into literals, instead use MOVI instruction to load
-them into registers and let the assembler turn them into literals as
-necessary.
-
-2015-08-12 Max Filippov <jcmvbkbc@gmail.com>
-gcc/
- * config/xtensa/constraints.md (define_constraint "Y"): New
- constraint.
- * config/xtensa/elf.h (ASM_SPEC): Add m(no-)auto-litpools.
- * config/xtensa/linux.h (ASM_SPEC): Likewise.
- * config/xtensa/predicates.md (move_operand): Match constants
- and symbols in the presence of TARGET_AUTO_LITPOOLS.
- * config/xtensa/xtensa.c (xtensa_valid_move): Don't allow
- immediate references to TLS data.
- (xtensa_emit_move_sequence): Don't force constants to memory in
- the presence of TARGET_AUTO_LITPOOLS.
- (print_operand): Add 'y' format, same as default, but capable of
- printing SF mode constants as well.
- * config/xtensa/xtensa.md (movsi_internal, movhi_internal)
- (movsf_internal): Add movi pattern that loads literal.
- (movsf, movdf): Don't force constants to memory in the presence
- of TARGET_AUTO_LITPOOLS.
- (movdf_internal): Add 'Y' constraint.
- * config/xtensa/xtensa.opt (mauto-litpools): New option.

-Subject: [PATCH 1/3] xtensa: reimplement register spilling
-
-Spilling windowed registers in userspace is much easier, more portable,
-less error-prone and equally effective as in kernel. Now that register
-spilling syscall is considered obsolete in the xtensa linux kernel
-replace it with CALL12 followed by series of ENTRY in libgcc.
-
-2015-08-18 Max Filippov <jcmvbkbc@gmail.com>
-libgcc/
- * config/xtensa/lib2funcs.S (__xtensa_libgcc_window_spill): Use
- CALL12 followed by series of ENTRY to spill windowed registers.
- (__xtensa_nonlocal_goto): Call __xtensa_libgcc_window_spill
- instead of making linux spill syscall.

-Subject: [PATCH 3/3] xtensa: fix _Unwind_GetCFA
-
-Returning context->cfa in _Unwind_GetCFA makes CFA point one stack frame
-higher than what was actually used by code at context->ra. This results
-in invalid CFA value in signal frames and premature unwinding completion
-in forced unwinding used by uClibc NPTL thread cancellation.
-Returning context->sp from _Unwind_GetCFA makes all CFA values valid and
-matching code that used them.

-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.

+Allow C99-depending features of libstdc++ with uClibc
+
+The libstdc++ code is fairly restrictive on how it checks for C99
+compatibility: it requires *complete* C99 support to enable certain
+features. For example, uClibc provides a good number of C99 features,
+but not C99 complex number support. For this reason, libstdc++
+completely disables many the standard C++ methods that can in fact
+work because uClibc provides the necessary functions.
+
+This patch is similar and highly inspired from
+https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58393, but implemented in
+a way that doesn't involve changing the configure.ac script, as
+autoreconfiguring gcc is complicated. It simply relies on the fact
+that uClibc defines the __UCLIBC__ definition.

+[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.

+Subject: [PATCH] xtensa: add -mauto-litpools option
+
+With support from assembler this option allows compiling huge functions,
+where single literal pool at the beginning of a function may not be
+reachable by L32R instructions at its end.
+
+Currently assembler --auto-litpools option cannot deal with literals
+used from multiple locations separated by more than 256 KBytes of code.
+Don't turn constants into literals, instead use MOVI instruction to load
+them into registers and let the assembler turn them into literals as
+necessary.
+
+2015-08-12 Max Filippov <jcmvbkbc@gmail.com>
+gcc/
+ * config/xtensa/constraints.md (define_constraint "Y"): New
+ constraint.
+ * config/xtensa/elf.h (ASM_SPEC): Add m(no-)auto-litpools.
+ * config/xtensa/linux.h (ASM_SPEC): Likewise.
+ * config/xtensa/predicates.md (move_operand): Match constants

+ (movsf_internal): Add movi pattern that loads literal.

+
+Spilling windowed registers in userspace is much easier, more portable,
+less error-prone and equally effective as in kernel. Now that register
+spilling syscall is considered obsolete in the xtensa linux kernel
+replace it with CALL12 followed by series of ENTRY in libgcc.

+ (__xtensa_nonlocal_goto): Call __xtensa_libgcc_window_spill
+ instead of making linux spill syscall.
