[LLVMdev] Assertion: replaceAllUses of value with new value of different type! being thrown all of a sudden

Hello,

I wonder if someone would know what is going on below.


All of a sudden I’m getting this assertion thrown:

Assertion failed: (New->getType() == getType() &&
"replaceAllUses of value with new value of different type!"), function
replaceAllUsesWith, file
/Users/meister/Development/externals-clasp/llvm36/lib/IR/Value.cpp, line 345.

It’s happening when DIBuilder::finalize is being called at the end of a source
file compilation.

Here’s the most illuminating debugging information I could pull out of a frame:


(lldb) 
frame #6: 0x0000000103a67c3e
clasp_boehm_d`llvm::DIDescriptor::replaceAllUsesWith(this=0x00007fff5fb9e288,

   396 	  MDNode *Node = const_cast<MDNode *>(DbgNode);
   397 	  const MDNode *DN = D;
   398 	  const Value *V = cast_or_null<Value>(DN);
-> 399 	  Node->replaceAllUsesWith(const_cast<Value *>(V));
   400 	  MDNode::deleteTemporary(Node);
   401 	}
   402 	
(lldb) print Node
(llvm::MDNode *) $3 = 0x00000001180b74c0
(lldb) call Node->dump()
!{i32 786468}

(lldb) call V->dump()
!{}

(lldb) 




Here’s the first part of the backtrace:

[LLVMdev] Assertion: replaceAllUses of value with new value of different type! being thrown all of a sudden

I'm not sure what's going on, but I do know this code wouldn't 
(or, shouldn't) compile on ToT for the last couple of months,
since `Value` and `MDNode` belong to different class hierarchies.

[LLVMdev] Assertion: replaceAllUses of value with new value of different type! being thrown all of a sudden

I forgot to mention this in my initial email.

The build of LLVM that I was using was commit
a0d5d7aed8e177cea381b3d054d80c212ece9f2c
The date on the commit is: Date:   Fri Sep 26 12:34:06 2014

Also:
Today I grabbed the ToT llvm/clang/clang-extra-tools  and I’m working on getting
my code to be compatible with it.

I can switch back and forth between the current ToT llvm and the old one.

Thanks,

.Chris.
