[GiNaC-list] Term ordering and compiling C++ code

[jros]

Very nice code, I like it a lot.

It's a pity that "ex::gethash() is not unique", that
would certainly improve things a lot.

Thanks,

Javier

Hi All,

Attached is the code for generating C/C++ code from a GiNaC expression
that pulls out subexpressions and declares them up front so that they
only have to be evaluated once.  The .hh file has documentation and a
simple usage example.

I hope this is useful.

I used it to reduce 50MB of code to under 300K and improved the running
time dramatically.
