+Subject: [PATCH] Fix uninitialised use in mips_split_move
+
+While testing the fix for PR91068, I hit an rtl checking failure
+while building newlib.  mips_split_move was decomposing an address that
+happened to be symbolic and then tried to access the REGNO of the base
+register field, which wasn't initialised but which by chance pointed to
+valid memory.

+Subject: [PATCH] gotools: fix compilation when making cross compiler
+
+libgo is "the runtime support library for the Go programming language.
+This library is intended for use with the Go frontend."
+
+gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but
+the linker will complain that it cannot find it.  That's because shared libgcc
+is not present in the install directory yet.  libgo.so was made without problem
+because gcc will emit -lgcc_s when compiled with -shared option.  When gotools
+were being made, it was supplied with -static-libgcc thus no link option was
+provided.  Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec
+for linking with libgo.so
+
+- GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation
+- Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html
+
+When 3-pass GCC compilation is used, shared libgcc runtime libraries will be
+available after gcc pass2 completed and will meet the gotools link requirement
+at gcc pass3

-    gcc: prevent the use of LDRD/STRD on ARMv5TE
-    
-    These instructions are for 64-bit load/store. On ARMv5TE, the CPU
-    requires addresses to be aligned to 64-bit. When misaligned, behavior is
-    undefined (effectively either loads the same word twice on LDRD, or
-    corrupts surrounding memory on STRD).
-    
-    On ARMv6 and newer, unaligned access is safe.
-    
-    Removing these instructions for ARMv5TE is necessary, because GCC
-    ignores alignment information in pointers and does unsafe optimizations
-    that have shown up as bugs in various places.

-    toolchain/gcc: .init and .fini need to pick one ISA
-    
-    The .init and .fini sections are built by concatenating code
-    fragments. Putting mips16 code in the middle of a mips32 code block
-    doesn't work. Make gcc built the magic crt stuff in no-mips16 mode.
-    
-    This is specific to 4.6-linaro but is probably portable to other gcc
-    flavors. Adding this to the t-libgcc-mips16 makefile fragment is a
-    hack not suitable for pushing upstream, but there is no mips/t-linux
-    or mips/t-uclibc and I am not going to touch gcc/configure for two
-    lines.

-    gcc: don't clobber stamp-bits with a symlink to itself
-    
-    Several versions of gcc have an issue in libstdc++v3 where the build may
-    clobber stamp-bits with a link to itself.  This doesn't manifest itself
-    on all systems.  On several Ubuntu systems, this doesn't appear to be a
-    problem, but it is an issue on Fedora 16 systems.
-    
-    To fix the issue, we'll simply filter out stamp-bits from the symlinks
-    to be generated.
-    
-    Note: gcc 4.4.7 is unaffected by this issue, so no fix is necessary
-    there.
