llvm dev - Mar 2010 - [LLVMdev] PTX target for LLVM?

Hi

I am interested to know: are there are any LLVM targets in the works
for Nvidia's PTX ISA?

Also if anyone knows about Ocelot (a project done by some students at
my school): it does the opposite of what I am trying to do (translates
PTX to LLVM  IR to run Cuda kernels on the CPU).

Thanks in advance.

I don't know of any, but that would be a great project if the nvidia
toolchain is sufficiently available for it to be useful to open source folks.

Helge Rhodin, a student at Saarland University, has already written a 
PTX backend for LLVM as part of his bachelor's thesis. We currently use 
it for a deferred shading system of a rasterizer.
The plan is to reintegrate it into the LLVM trunk, but we have not yet 
made any steps into this direction.
