[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.

If that doesn't clear things up, ask on the list or IRC channel. -- Misha Brukman :: http://misha.brukman.net :: http://llvm.cs.uiuc.edu

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. On 4/25/05, Misha Brukman <brukman at uiuc.edu> wrote:> On Sun, Apr 24, 2005 at 07:15:03PM +0800, Tzu-Chien Chiu wrote: > > i'd like to know if there is any plan or existing work to add a Aho's > > trig language like code generator generator? > > I'm not aware of either the trig language code generator nor any work to > implement it in LLVM. > > > "...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? > > 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).
