            Bug ID: 20126
           Summary: clang assertion failure with OpenCL function: "Only
                    storage fields have tail padding!"
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P

Preprocessed source

I'm getting an assertion when trying to compile an OpenCL function:

CGRecordLayoutBuilder.cpp:526: void <anonymous
namespace>::CGRecordLowering::clipTailPadding(): Assertion `Prior->Kind ==
MemberInfo::Field && !Prior->FD && "Only storage fields have tail padding!"'

It only happens when I compile using -triple r600.  When I compile for x86_64
there is no assertion failure.  I've attached the preprocessed .cl file and
script for reproducing. This may be related to bug 19514.
