but does it have default values ?

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

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

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

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

I have a function address held in an uint64_t. I would like to cast the function address to a function prototype and create a call to the function in LLVM. How could I do this ? Thanks Xin

You mean besides fixing the source of your benchmark so it's valid C? Not at the moment...

Is there any way to stop this ? /home/socrates/llvm/llvm-3.0.src/benchmarks/powerstone/crc/crc.c:67:1: error: 'main' must return 'int' void main() ^ 1 error generated. Thanks

I understand that we need to push the address to a register then branch using the register. But i am asking why there is a trampoline there such that a call to foo is first branched to an snippet and the snippet branches to the X86CompilationCallback. is this snippet necessary ?

Using uintptr_t is the way to hold pointer values.
