[LLVMdev] C-to-verilog

Hello,

I wanted to tell the LLVM developers list about http://www.c-to-verilog.com.

I created this website to provide free on-line compilation of C into
Verilog. I use LLVM as the C parser and optimizer. I have been working on
this project for 2 years now.

I would like to thank Chris, Vikram and the rest of the LLVM developers. I
am very happy with the LLVM infrastructure, documentation, and
organization.  Thanks to LLVM, I was able to focus on hardware-circuit
optimizations.

After clang parses the code and LLVM optimizes the IR, I wrap the IR with my
own structures. I extract parallelism from loops whenever possible and
create pipelined designs.

I've implemented a limited "Modulo Scheduler" (Software pipelining). This
pass pipelines loops and works on LLVM IR. I would like to donate the
pipelining code back to LLVM.
