Bug ID: 25540
Summary: Relocation R_PPC64_REL24 overflow
Product: libraries
Version: trunk
Hardware: Other
OS: Linux
Status: NEW
Keywords: ABI
Severity: normal
Priority: P
Component: Generic Execution Engine Support
Assignee: unassignedb...@nondot.org

script to reproduce
We run into the following when JITting code on PowerPC:
Relocation R_PPC64_REL24 overflow
UNREACHABLE executed at
llvm/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp:987!
Attached is a script to reproduce the problem: it generates a single file with
a large number (100) of large functions, then JITs it. The offsets grow until
they hit out of bounds. One level up the stack trace, same file line 1457, is
supposed to handle the range overflow case, but still uses the same relocation
type.
The above is not what we actually do in our code, but this allows the same code
path to hit with only llvm+clang.
Thanks!
