SSA incorporates two new
high-level intermediate languages (GENERIC and 
GIMPLE), an optimization
framework for GIMPLE based on the Static Single 
Assignment (SSA)
representation, several SSA-based optimizers and various 
other improvements to
the internal structure of the compiler that allow new 
optimization
opportunities that were difficult to implement before." 
 
This is a language
independent internal representation and is goood news 
for the d.gnu project,

Cool. Thanks for posting the links.

I'm looking forward to being able to use GENERIC. I'm starting to
bump up against "the hard stuff" in converting the D tree from DMD
to a C++ tree. I've almost got classes supported but it's temporarily
put on the back burner until I get the method name mangled. For some
reason the call site mangles the name fine but the function definition is
unmangled. very strange. Maybe once the CPP front end is converted
to GENERIC/GIMPLE will be easier to see what is going on. Of course
the mangling should be done by D but I haven't even tried that yet...
