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? If pType isIntegerType, I need to know if it is signed or unsigned... How to achieve this? Thx Alex llvm::Type * getRandomValid_IntegerType(llvm::LLVMContext &C) { using namespace llvm; //--- determine num of bits between allowed bits int rI=randInt(IntegerType::MIN_INT_BITS,IntegerType::MAX_INT_...

Hi All, I am trying to check if a Value type is a int32 pointer by using if(T == Type::getInt1PtrTy(Context, AS)) ... I am trying to understand the AS (address space). How do I get it? Thanks.

Hi, You don't need to care about address spaces to check for an int32*: if (T->isPointerTy()) { const Type* intT = cast<PointerType>(T)->getElementType(); if (intT->isIntegerTy() && intT->getPrimitiveSizeInBits() == 32) cout << "Yeah!" << endl; } Also, to create a pointer type, if you don't care about address space at all, use the unqualified version: const Type* ptrT = PointerType::getUnqual(intT); cheers, --renato

Hi Sanjay, unfortunately that patch does not help in my case. Here's the IR that fails to get fully optimized: target datalayout = "e-m:e-i64:64-f80:128-n8:16:32:64-S128" target triple = "x86_64-unknown-linux-gnu" define fastcc zeroext i1 @testfunc(i8** noalias nocapture readonly dereferenceable(8)) unnamed_addr { entry-block: %1 = load i8*, i8**

Hello, I am trying to figure out, what vrp propagation does in llvm. I tried this program: #include <stdio.h> int main() { int s = 0; int j = 0; for (int i = 0; i < 100; i++) { j = j+i+1; s+=j; } return (s+j); } And got this under optimized version ( I don't want everything to be eliminated) define i32 @main()
