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: unassignedb...@nondot.org
Reporter: axel.naum...@cern.ch

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:
