[AVR] clang++ crashes when building c++ program with virtual functions
For the following program
class HardwareSerial {
public:
virtual int available(void);
};
int HardwareSerial::available(void) {
return 1;
}
Build it with command clang++ --target=avr -mmcu=atmega328 -O3 -S b.cc, the following error rises
clang++: /home/benshi/work/llvm-project/llvm/lib/IR/Constants.cpp:2201: static llvm::Constant* llvm::ConstantExpr::getBitCast(llvm::Constant*, llvm::Type*, bool): Assertion `CastInst::castIsValid(Instruction::BitCast, C, DstTy) && "Invalid constantexpr bitcast!"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
