-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.

-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.

-* 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.

-Subject: [PATCH] UPDATE: Fix handling complex PIC moves.
-
-fwprop is putting in the REG_EQUIV notes which are involving the
-constant pic unspecs.  Then, loop may use those notes for
-optimizations rezulting in complex patterns that are not supported by
-the current implementation. The following piece of code tries to
-convert the complex instruction in simpler ones.
-
-The fix is done in development tree: [arc-4.8-dev b55922d] 
-and will be a part of the next release of ARC GNU tools.
-Once that new release happens this patch must be removed.

-
-The arc_legitimate_pc_offset_p condition is too lax. Updated it.
-
-The fix is done in development tree: [arc-4.8-dev f00b0f1] 
-and will be a part of the next release of ARC GNU tools.
-Once that new release happens this patch must be removed.

-Subject: [PATCH] Don't allow mcompact-casesi for ARCv2
-
-The compact casesi is not working for arcv2 processors family as it
-makes use of the add_s rx,rx,pcl instruction which is only valid for
-arc6xx and arc700 processors. Also not having this instruction makes
-no much sens to change the compact-casesi pattern to use normal add
-instructions as it nullifies the advantage of short instruction use.
-The default casesi pattern betters suits the arcv2 architecture.
-
-The fix is done in development tree: [arc-4.8-dev 0946382] 
-and will be a part of the next release of ARC GNU tools.
-Once that new release happens this patch must be removed.
