在Cpu0ISelLowering.cpp 中,注册了 setOperationAction(ISD::SREM, MVT::i32, Expand) 等操作,将 ISD::SREMlowering到 ISD::SDIVREM(有关于 Expand 的参考资料,可以查看http://llvm.org/docs/WritingAnLLVMBackend.html#expand)。然后实现了 PerformDAGCombine() 函数,将 ISD::SDIVREM 根据它是除法还是求余(...
LLVM IR处理这个问题的方式是引入Phi节点,Phi节点是一种特殊的操作,它允许操作中通过判断控制流的流向,来选择要赋值的值,从而避免了多赋值问题。 这种操作只有在 clang 启用优化的情况下才会生成,如果是 O0 不开优化时,LLVM 则会使用内存访问来解决问题,也就是将值写入同一个内存位置,再在需要赋值时从内存位置读...

Fromthis post, it looks like this error is expected as the CPU fp16 backend does not have support for Conv layers. For now, I am just working with a fp32 version of my model since that is all I was able to convert to ONNX, but ideally I would like to convert it to ONNX using...
Its purpose is to detect if there are any llvm::UIToFP or llvm::SIToFP vector cast instructions from [u]long to float. If so all the functions in the module are marked with the attribute -neon to disable Neon in the backend. We have to do this for all functions, rather than just...

🐛 Describe the bug Situation I'm reporting a "bug", however there is no explicit error message and it's a change in the observed behavior during inference. This begun with torch==2.4.0 but only on Windows and when running inference on CP...
