[llvm-dev] Link error: undefined reference to APIInt functions

[Hayrapetyan, Anahit via llvm-dev]

Hi,


I’m getting link error when compiling an executable where llvm::APIInt is used.

Following is the error:


/usr/local/include/llvm/ADT/APInt.h:1372: undefined reference to `llvm::APInt::countLeadingZerosSlowCase() const'

The source file is a simple program, where ConstantInt’s getZExtValue function is called. If I comment out this part, everything goes just fine.


uint64_t val = or_const_op->getZExtValue();


Could you please suggest what the cause of this problem might be?


Thanks,

Anahit.
