llvm dev - Apr 2005 - [LLVMdev] trig language-like code generator generator

i'd like to know if there is any plan or existing work to add a Aho's
trig language like code generator generator?

"...If you are starting a new port, we recommend that you write the
instruction selector using the SelectionDAG infrastructure."

any other things i should know before i write one?

thank you.

I'm not aware of either the trig language code generator nor any work to
implement it in LLVM.

You should read these:

http://llvm.cs.uiuc.edu/docs/WritingAnLLVMBackend.html
http://llvm.cs.uiuc.edu/docs/TableGenFundamentals.html

If you're unsure of how things are implemented, take a look at how
similar things are done in X86, PowerPC, Alpha or IA64, they all have
SelectionDAG-based instruction selectors (*ISelPattern.cpp).  If that
doesn't clear things up, ask on the list or IRC channel.

Trig is a code generator generator?  Is there any documentation for it 
available anywhere?

yes, i did read those document. but i don't target any existing
hardware. i need a compiler during the hareware design phase (i work
for an ihv). preferrable a bnf syntax/rule/cost-driven and code
generator generator. dynamic programming ones like twig, burg, beg,
etc.
