[LLVMdev] Any suggestion for "Unknown instruction type encountered" error?
Hello all,
I was playing with LLVM pass. I changed the
lib/Transforms/Hello/Hello.cpp 's content to be my own pass. Then I make
install the pass and use an example test1.c to see whether it works or not.
When I run example using the following command:
clang -emit-llvm test1.c -c -o test1.bc
opt -load ../build_llvm/Debug+Asserts/lib/LLVMHello.so -hello < test1.bc >
/dev/null
It shows the following error:
Unknown instruction type encountered!
UNREACHABLE executed at include/llvm/InstVisitor.h:120!

1. Running pass 'Function Pass Manager' on module
'<stdin>'.
2. Running pass 'Hello Pass' on function '@main'
I will illustrate the pass code, the test1 example, and the IR generated
below, so that anyone could help me or give me some suggestion. Thanks.
The Hello.cpp pass is as the following:
#define DEBUG_TYPE "hello"
#include "llvm/Pass.h"
#include "llvm/IR/Module.h"
#include "llvm/InstVisitor.h"
#include "llvm/IR/Constants.h"
#include "llvm/IR/IRBuilder.h"
#include "llvm/Support/raw_ostream.h"
namespace {
struct Hello : public llvm::FunctionPass, llvm::InstVisitor<Hello> {
private:
llvm::BasicBlock *FailBB;
public:
static char ID;
Hello() : llvm::FunctionPass(ID) {FailBB = 0;}
virtual bool runOnFunction(llvm::Function &F) {
visit(F);
return false;
}
llvm::BasicBlock *getTrapBB(llvm::Instruction &Inst) {
if (FailBB) return FailBB;
llvm::Function *Fn = Inst.getParent()->getParent();
llvm::LLVMContext& ctx = Fn->getContext();
llvm::IRBuilder<> builder(ctx);
FailBB = llvm::BasicBlock::Create(ctx, "FailBlock", Fn);
llvm::ReturnInst::Create(Fn->getContext(), FailBB);
return FailBB;
}
void visitLoadInst(llvm::LoadInst & LI) {
}
void visitStoreInst(llvm::StoreInst & SI) {
llvm::Value * Addr = SI.getOperand(1);
llvm::PointerType* PTy =
llvm::cast<llvm::PointerType>(Addr->getType());
llvm::Type * ElTy = PTy -> getElementType();
if (!ElTy->isPointerTy()) {
llvm::BasicBlock *OldBB = SI.getParent();
llvm::errs() << "yes, got it \n";
llvm::ICmpInst *Cmp = new llvm::ICmpInst(&SI,
llvm::CmpInst::ICMP_EQ, Addr,
llvm::Constant::getNullValue(Addr->getType()), "");
llvm::Instruction *Iter = &SI;
OldBB->getParent()->dump();
llvm::BasicBlock *NewBB = OldBB->splitBasicBlock(Iter,
"newBlock");
OldBB->getParent()->dump();
}
}
};
char Hello::ID = 0;
static llvm::RegisterPass<Hello> X("hello", "Hello
Pass", false, false);
}
The test1.c example is as the following:
#include <stdio.h>
void main() {
int x;
x = 5;
}
The IR for the example after adding the pass is as the following:
define void @main() #0 {
entry:
%x = alloca i32, align 4
%0 = icmp eq i32* %x, null
br label %newBlock
newBlock: ; preds = %entry
store i32 5, i32* %x, align 4
ret void
}
any suggestion?

This is a static list in the compiler, same as documented on llvm.org/docs/LangRef.html . My guess is that your .bc file is from a very different version of llvm than your 'opt' binary. Perhaps you're using a clang installed on the system and an opt your built yourself? We sometimes change the instruction numbering for the encoding in the .bc files. Does 'opt -verify < test1.bc' work? Another alternative is that you've managed to form invalid IR in some other way, or corrupted memory. Have you tried building 'opt' and LLVMHello.so with debug (so that llvm's assertions are enabled)? And what about running the 'opt' command under valgrind?
