powerpc64-ld infinite loopbinutils-2_31-branch
If this code dealing with possible conversion of inline plt sequences
is ever executed, ld will hang. A binary with such sequences and of
code size larger than approximately 90% the reach of an unconditional
branch is the trigger. Oops.
* elf64-ppc.c (ppc64_elf_inline_plt): Do increment rel in for loop.
(cherry picked from commit 435edf0bf231240ccecb474b74ebb49dc8db2633)
