I want to get a reference to this time series object
I'm trying to get a reference to this object in C SWX.RET[1:6,c("SBI,"SPI","SII")] While i am able to access and use a plain SWX.RET object, I'm getting confused on how to create an object with the array subscripts like above. Here is what I tried to do. It doesn't work because "[" is obviously not an operation or function on SWX.RET. So how do I

[RFC] A new multidimensional array indexing intrinsic
...on from. The remaining arguments are a list of pairs. Each pair contains a dimension stride, and an offset with respect to that stride. ### Semantics: `llvm.multidim.array.index.*` represents a multi-dimensional array index, In particular, this will mean that we will assume that all indices `<idx_i>` are non-negative. Additionally, we assume that, for each `<str_i>`, `<idx_i>` pair, that `0 <= idx_i < str_i`. Optimizations can assume that, given two llvm.multidim.array.index.* instructions with matching types: ``` llvm.multidim.array.index.* <ty> <ty>* <...

[LLVMdev] RE: Question about Global Variable
...all those IR instructions, for the first three, it is ok, as the following GetElementPtrInst *GEP = new GetElementPtrInst( pGVars, idxVec, "GetAryElement", InsertPos); Value *ldAddr = new LoadInst(GEP,"LdAryAddr",InsertPos); Value *ldAddr1 = new LoadInst(numidx, "idx_i", InsertPos); After this I need construct another getelementptr, and from the above IR code, the second getelementptr take the result of load as parameters. But there is no such prototype construction api for this case. The correct one should be as the following, GetElementPtrInst(Value *P...
