            Bug ID: 40312
           Summary: LTO fails with "Called function is not the same type
                    as the call"
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Interprocedural Optimizations
          Assignee: unassignedbugs at nondot.org
          Reporter: pirama at google.com
                CC: llvm-bugs at lists.llvm.org

This happens with LTO and CFI:

Called function is not the same type as the call!
  tail call void @EC_KEY_free(%struct.ec_key_st* %5) #22, !dbg !33425
in function _ZN9keymaster5EcKey13EvpToInternalEPK11evp_pkey_st
LLVM ERROR: Broken function found, compilation aborted!

The failures are caused by Clang change r335385 (originally landed as r335284)
and LLVM change r335145.

I am attaching lld's repro.tar which can be run as:
  $ tar xvf repro.tar
  $ cd repro
  $ <path-to-lld> @response.txt

The problem is likely in the Clang change as reverting the two changes above
and running the link step doesn't fix the issue.  I am working on narrowing
down the failure to a smaller repro (any tips on doing so with LTO are much
appreciated :)
