We're already using 5.x as default, and have 4.9.x on the lower side
together with 7.x (7.1) on the higher side.

http://gcc.gnu.org/ml/gcc-patches/2008-10/msg00269.html
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.

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] PR other/56780
* libiberty/configure.ac: Move test for --enable-install-libiberty
outside of the 'with_target_subdir' test so that it actually gets
run. Add output messages to show the test result.
* libiberty/configure: Regenerate.
* libiberty/Makefile.in (install_to_libdir): Place the
installation of the libiberty library in the same guard as that
used for the headers to prevent it being installed unless
requested via --enable-install-libiberty.

libiberty: fix --enable-install-libiberty flag [PR 56780]
Commit 199570 fixed the --disable-install-libiberty behavior, but it also
added a bug where the enable path never works because the initial clear
of target_header_dir wasn't deleted. So we end up initializing properly
at the top only to reset it at the end all the time.

From 6d852ffb43b111a39162135c95249e749c4e285b Mon Sep 17 00:00:00 2001

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>

* 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.

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.
