私のllvm
コードでは、次のコードを使用して、イテレータInsertPosが基本ブロックの最後の命令を指しているかどうかを確認しようとしています。
BasicBlock::iterator InsertPos = BB->begin();
LLVMContext &Context = BB->getContext();
while ( !( isa<CallInst>(InsertPos) ||
( InsertPos == BB->getTerminator() ) ) ) // <-- Error here
++InsertPos;
ただし、clang
次のエラーが表示されます。
Basic2.cpp:82:54: error: use of overloaded operator '==' is ambiguous (with operand types 'BasicBlock::iterator' (aka 'ilist_iterator<llvm::Instruction>')
and 'llvm::TerminatorInst *')
while ( !( isa<CallInst>(InsertPos) || ( InsertPos == BB->getTerminator() ) ) )

これを行う正しい方法は何ですか?
