+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.

+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.
