[Julian Seward <jseward@ac...>]

Greetings, y'all.

I just committed to the cvs head, initial support for MMX instructions.
Just MMX, not SSE or SSE2.  SSE and SSE2 are for later; a staged approach
keeps the resulting code simpler and more maintainable (I hope).

Most MMX instructions now work.  What would be very useful is for
people who have apps with MMX instructions, to check out and build the
head [details below] and then run their MMXish apps on it.  There will 
be initial breakage, but the sooner this is done, the sooner we will 
have working MMX support :-)

So, can anyone help out?

If this all works out satisfactorily, I will seriously consider backporting
it to the stable branch (the >= 1.9.4 series).

Building from anon cvs:
You need autoconf >= 1.5.  Apart from that it should be easy.

Here's how:

cvs -d:pserver:anonymous@...:/cvsroot/valgrind login

When prompted for a password for anonymous, simply press the Enter key.

cvs -z3 -d:pserver:anonymous@...:/cvsroot/valgrind 
          co valgrind

cd valgrind
./autogen.sh
./configure --prefix=....
make
make install
