Hi, I'm trying to do a Debug build for the 1st time and I keep getting this assertion: llvm-tblgen: CodeGenDAGPatterns.cpp:64: llvm::EEVT::TypeSet::TypeSet(llvm::ArrayRef<llvm::MVT::SimpleValueType>): Assertion `!VTList.empty() && "empty list?"' failed. I do not know what list this assertion is referring to. Does anyone know? I always did Release builds before without any problem.

Hi Tom, Matt, I'm working on a project that needs few coherent atomic operations (HSA mode: load, store, compare-and-swap) for std::atomic_uint in HCC. the attached patch implements atomic compare and swap for SI+ (untested). I tried to stay within what was available, but there are few issues that I was unsure how to address: 1.) it currently uses v2i32 for both input and output. This

thanks for the help ..I do add the chain and the result. My code is like this ... SDValue Ops[] = { load->getChain(), load->getOperand(1), load->getBasePtr(), des }; DAG.getNode(CustomOpc, NodeTys, Ops, 4); thanks again! shrey On Thu, Nov 12, 2009 at 4:41 PM, Anton Korobeynikov <anton at korobeynikov.info> wrote: >> My problem is that the second call asserts inside

Hi Sanjay, Thanks, I saw this flag and it's definitely should be considered, but it appeared to me to be static characteristic of target platform. I'm not sure how appropriate it would be to change its value from a front-end. It says "Has", while optional flag would rather say "Uses" meaning that implementation cares about floating point exceptions. Regards, Sergey
