            Bug ID: 32650
           Summary: RuntimeDyldELF: Relocation R_PPC64_REL24 overflow
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: PowerPC
          Assignee: unassignedbugs at nondot.org

IR reproducing the assertion

Running attached IR file as

$ lli -jit-kind=orc-mcjit R_PPC64_REL24.ir

triggers

Relocation R_PPC64_REL24 overflow
UNREACHABLE executed at
.../src/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp:761!


The IR is the minimized IR for

$ echo '#include <vector>
std::vector<char> l; int main() { return 0;}' | clang -x c++  -std=c++14 -c
-Xclang -emit-llvm -fno-use-cxa-atexit - -o -

on a Power8 PPC64le. llvm was built as Debug on CentOS 7.3 with GCC 6.3.0.



I bisected; the commit that introduced this failure was the (otherwise crucial,
wonderful) commit:



commit 04d404bad2a4338841d5ab5f0ec3908bbd62fa1a
Author: Lang Hames <lhames at gmail.com>

    Re-apply r278065 (Weak symbol support in RuntimeDyld) with a fix for ELF.
