llvm dev - Nov 2009 - [LLVMdev] Poolalloc asserts when passing in pool descriptors

Hi,

The poolalloc library fails in TransformFunctionBody.cpp, line 746

---
Value *ArgVal = ConstantAggregateZero::get(PoolAllocate::PoolDescPtrTy);
---

opt -load /path_to_lib/libpoolalloc.dylib -poolalloc constaggr.bc -o 
opt.bc -f

triggers the problem (bc file attached).

Assertion failed: ((isa<StructType>(Ty) || isa<ArrayType>(Ty) || 
isa<VectorType>(Ty)) && "Cannot create an aggregate zero of 
non-aggregate type!"), function get, file lib/VMCore/Constants.cpp, line 
859.

Changing it to
Value *ArgVal = Constant::getNullValue(PoolAllocate::PoolDescPtrTy);

which was used in revision 72001, fixes the problem.

Dear Harmen,

You're correct.  I've applied the fix.

Thanks!
