Hello. Could you please tell me why am I not able to recognize (with LLVM built from the SVN code in Apr 25, 2018) the LLVM IR intrinsic ctpop (described at https://llvm.org/docs/LangRef.html#llvm-ctpop-intrinsic) in the following program: int PopCnt_Simple(int x) { int numBits = 0; int i; //for (i = 0; i < 32; i++) { for (i = 0; x != 0; i++) { if (x & 1) numBits++; x >>= 1; } return numBits; } I also did check the following code, getting ins...

Hello, I'm compiling LLVM with MSVC at the moment, I've got the following warning: BitstreamReader.h(327) : warning C4334: '<<' : result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift intended?) in line uint64_t Piece = Read(NumBits); if ((Piece & (1U << (NumBits-1))) == 0) Is this warning relevant?

I think I might have found a bug in the exection engine's 'constants folding'. Basically APInt's parameters are the wrong way round. Line 577 for lib/ExecutionEngine/ExecutionEngine.cpp :- case Instruction::PtrToInt: { GenericValue GV = getConstantValue(Op0); uint32_t PtrWidth = TD->getPointerSizeInBits(); GV.IntVal = APInt(PtrWidth,

Hi, I have a Type * which may come from an IntegerType as shown below: Type.getIntegerBitWidth() tells me numBits. But how to extract the IntegerType.getSignBit?

Hi, I want to compute the bitwise 'and' between two values of type int1:  %x = and %a, %b  . Which is the LLVM instruction that creates this? I only found the APInt class, whose constructor is:  APInt(unsigned numBits, uint64_t val, bool isSigned = false) and which provides the bitwise AND operation: APInt  llvm::APIntOps::And (const APInt &LHS, const APInt &RHS)   Bitwise AND function for APInt. Is this the best way to build the 'and' instruction that I need? If so, how can I send the valu...

It will use llc to compile code rather than gcc, and llc does handle arbitrary sized integers. Ciao, Duncan.

Dear all, I have following kind of character vector: Vec <- c("344426", "dwjjsgcj", "123sgdc", "aagha123", "sdh343asgh", "123jhd51") Now I want to split each element of this vector according to?numeric?and string element. For example in the 1st element of that vector, there is no string element. Therefore I should get a vector of

Hi all, We're hitting some walls here when generating the correct structure layout for specific C++ ABI requirements, and I was wondering how much StructLayout could help. For instance, the ABI has some complicated rules on the size of derived classes (http://www.codesourcery.com/public/cxx-abi/abi.html#class-types) and LLVM struct type cannot reflect that in full. Example: // CHECK:
