From 435edf0bf231240ccecb474b74ebb49dc8db2633 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Wed, 11 Mar 2020 14:43:16 +1030 Subject: [PATCH] powerpc64-ld infinite loop 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.
