package/gcc: remove version 5.5.5 

gcc 9.2 is around, gcc 8.4 is the default version, so drop
5.5 in order to reduce the gcc choice.

GCC 5.5 was disabled for Glibc based toolchain since Glibc
2.30 needs GCC 6.2 or later.

See:
https://sourceware.org/ml/libc-alpha/2019-08/msg00029.html

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.

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

Date: Thu, 6 Aug 2015 01:16:02 +0300
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.
