similar to: [LLVMdev] llvm interpreter

I do not know too much about clang, is opencl publicly supported in clang ? how about cuda ? Thanks Xin

It seems llvm interpreter only supports a limited number of external functions. fmod, in particular is not supported. any reason why it is not supported ?

I don't think so, but you should check source code.

but does it have default values ?

You specify shader model, bit size and etc. arch-specified parameters though -march, -mattr and -mcpu, but AFAIK, PTX backend does not use the GPU thread/block/grid size information in optimization yet.

It might be as simple as modifying the TableGen file to not know that the register exists. 2) Use inline asm to put the constant into that register and fetch it from that register. The real question is: what larger goal are you

can we get a confirmation on who is coming tomorrow ?

I have a constant parameter in a LLVM function. Is there a way to reserve a CPU register such that it also holds the value of the parameter in LLVM x86 codegen ? Thanks Xin

I am wondering that how does the LLVM PTX backend find out the constraints on executing GPU thread/block/grid size ( i.e. a block can at most have 1024 threads). Can anyone point me to the code ? I need information in the optimizer, how can I get it ? Thanks Xin

sounds like a good idea to me. but one of the current issues of back-patching in the LLVM is that the back-patching is not done atomically on some of the architectures, i.e. Intel x86. and this makes LLVM JIT not thread-safe in lazy compilation mode. what we need to make sure is that the "updating the resolution for a given symbol" you mentioned is done in an atomic fashion. also, how

It would be fun to meet some other LLVM developers in TO, 7:00 on wed at beer bistro should work for me.
