            Bug ID: 36798
           Summary: [PPC64] V2 ABI: relocation R_PPC64_ADDR16_DS out of
                    range when linking against c-runtime
           Product: lld
           Version: unspecified
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: ELF
          Assignee: unassignedbugs at nondot.org
          Reporter: sfertile at ca.ibm.com
                CC: llvm-bugs at lists.llvm.org

*** Note that testing was done with https://reviews.llvm.org/D44483 and an
experimental fix for https://bugs.llvm.org/show_bug.cgi?id=36755. The first
patch is needed to add support for the PPC64LE target as well as add the
missing .TOC. symbol.

When linking against the C runtime, a relocation in _start is out of range.
min_main.c:
int main(void) {
  return 55;
}

I got the verbose link command with:
~/install/LLD/bin/clang -fuse-ld=/home/sfertile/install/LLD/bin/ld.lld  -v
min_main.c
