Hi All, I ran into what I think is a linker bug around structural uniquing of types when trying to make a long-overdue upgrade from LLVM 3.3 to LLVM 3.8.0. Verification can fail after linking together two well-formed modules due to mismatched pointer types. What happens is that both of the types in the source module get mapped to the same type in the destination module. The old behaviour was

Thanks for the quick response Rafael, that's what I hoped to hear - I'll see what I can do! The original repro is ~150000 lines of IR so I'll see if I can reduce it :) - Tim On Thu, Mar 24, 2016 at 10:08 AM, Rafael Espíndola < rafael.espindola at gmail.com> wrote: > On 24 March 2016 at 12:18, Tim Armstrong via llvm-dev > <llvm-dev at lists.llvm.org> wrote: >
