* ================== PLATFORM CHANGES =================
mips64-linux support
* Support for MIPS64 LE and BE running Linux. Valgrind has been tested
on MIPS64 Debian Squeeze and Debian Wheezy distributions.
* Support for MIPS DSP ASE on MIPS32 platforms.
Support for s390x Decimal Floating Point instructions on hosts that
have the DFP facility installed.

Supported platforms
-------------------
- MIPS32 and MIPS32r2 platforms are currently supported.
- MIPS32 and MIPS64 platforms are currently supported.
- Both little-endian and big-endian cores are supported.
- MIPS DSP ASE on MIPS32 platforms is supported.
Building V for MIPS

expects that native GCC is configured correctly and optimized for the platform.
Yet, this may not be the case with some Debian distributions which configure
GCC to compile to "mips1" by default. Depending on a target platform, using
CFLAGS="-mips32r2" or CFLAGS="-mips32" will do the trick and compile Valgrind
correctly.

Limitations
-----------
- Currently, memcheck, massif, lackey, callgrind and none are supported.
- Support for helgrind, drd and exp-ptrcheck is still incomplete.
- Some Valgrind tests for MIPS expect mips32r2 architecture and will not
compile when target is one of the older instruction sets.
- Some gdb tests will fail when gdb (GDB) older than 7.5 is used and gdb is
not compiled with '--with-expat=yes'.
- You can not compile tests for DSP ASE if you are using gcc (GCC) older
then 4.6.1 due to a bug in the toolchain.
- Older GCC may have issues with some inline assembly blocks. Get a toolchain
based on newer GCC versions, if possible.
