+* Added support for TSX lock elision of pthread mutexes on powerpc32, powerpc64
+  and powerpc64le.  This may improve lock scaling of existing programs on
+  HTM capable systems.  The lock elision code is only enabled with
+  --enable-lock-elision=yes.  Also, the TSX lock elision implementation for
+  powerpc will issue a transaction abort on every syscall to avoid side
+  effects being visible outside transactions.

+  AArch64.  Contributed by ARM Ltd.

+* Support for MIPS o32 FPXX, FP64A and FP64 ABI Extensions.
+  The original MIPS o32 hard-float ABI requires an FPU where double-precision
+  registers overlay two consecutive single-precision registers.  MIPS32R2
+  introduced a new FPU mode (FR=1) where double-precision registers extend the
+  corresponding single-precision registers which is incompatible with the
+  o32 hard-float ABI.  The MIPS SIMD ASE and the MIPSR6 architecture both
+  require the use of FR=1 making a transition necessary.  New o32 ABI
+  extensions enable users to migrate over time from the original o32 ABI
+  through to the updated o32 FP64 ABI.  To achieve this the dynamic linker now
+  tracks the ABI of any loaded object and verifies that new objects are
+  compatible.  Mode transitions will also be requested as required and
+  unsupportable objects will be rejected.  The ABI checks include both soft and
+  hard float ABIs for o32, n32 and n64.
+
+  GCC 5 with GNU binutils 2.25 onwards:
+  It is strongly recommended that all o32 system libraries are built using the
+  new o32 FPXX ABI (-mfpxx) to facilitate the transition as this is compatible
+  with the original and all new o32 ABI extensions.  Configure a MIPS GCC
+  compiler using --with-fp-32=xx to set this by default.
