Hello all,<br>
I was playing with LLVM pass. I changed the<br>
lib/Transforms/Hello/Hello.cpp 's content to be my own pass. Then I make<br>
install the pass and use an example test1.c to see whether it works or<br>
not. When I run example using the following command:<br>
clang -emit-llvm test1.c -c -o test1.bc<br>
opt -load ../build_llvm/Debug+Asserts/<u></u>lib/LLVMHello.so -hello < test1.bc<br>
> /dev/null<br>
<br>
It shows the following error:<br>
<br>
Unknown instruction type encountered!<br>
UNREACHABLE executed at include/llvm/InstVisitor.h:<u></u>120!<br>
</blockquote>
<br></div>
The error message here means that the type of instruction -- alloca, add, sub, load, store, etc. -- is one that did not exist in the compiler at the time that opt was built. This is a static list in the compiler, same as documented on <a href="http://llvm.org/docs/LangRef.html" target="_blank">llvm.org/docs/LangRef.html</a> .<br>
<br>
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?<br>
<br></blockquote><div> </div><div> I am sure that the version of llvm and opt are the same since I build them at the same time.<br><br>opt -version<br>LLVM (<a href="http://llvm.org/">http://llvm.org/</a>):<br>LLVM version 3.3svn<br>

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?<br>

1. Running pass 'Function Pass Manager' on module '<stdin>'.<br>
2. Running pass 'Hello Pass' on function '@main'<br>

I will illustrate the pass code, the test1 example, and the IR generated<br>
below, so that anyone could help me or give me some suggestion. Thanks.<br>
<br>
The Hello.cpp pass is as the following:<br>

You don't seem to ever use this builder?<br>

The test1.c example is as the following:<br>
<br>
#include<stdio.h><br>
void main() {<br>
int x;<br>
x = 5;<br>
}<br>
<br>
The IR for the example after adding the pass is as the following:<br>
define void @main() #0 {<br>
entry:<br>
%x = alloca i32, align 4<br>
%0 = icmp eq i32* %x, null<br>
br label %newBlock<br>
<br>
newBlock: ; preds = %entry<br>
store i32 5, i32* %x, align 4<br>
ret void<br>
}<br>
<br>
<br>
any suggestion?<br>
