How do you determine if a shift is signed or not? ashr = always signed? lshr = always unsigned? shl = always signed? The CmpInst has the "isSigned()" function, but it appears that every other Instruction I've looked at doesn't seem to have this. -------------- next part -------------- An HTML attachment was scrubbed...

There isn't an isSigned() function because the query doesn't really make sense. LLVM IR doesn't in general track whether a value is signed or unsigned. -Eli

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 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 value uint64_t stored in the va...

...u're going to be pattern-matching the constant arguments anyway. I guess our opinions differ there, then. I think the code savings/generalization/simplification you get from expressing the parameterization as constant parameters compared to having separate intrinsics is not huge. if (Ty->isSigned())   IID = fixsmul else   IID = fixumul if (Ty->isSigned())   SignedParam = ConstantInt(1) else   SignedParam = ConstantInt(0) The same goes for legalization/expansion. The semantics would be described in specific operations, not generalized ones ('ext') so there isn't much...
