From 247d6c4c14769b7576d810a381a68e35388ee874 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Thu, 16 Feb 2017 12:23:12 +1030 Subject: [PATCH] PR21132, hppa-linux pie support doesn't work This fixes a long-standing hppa bug seen when generating PIEs, and I think possible to trigger with forced local symbols in shared libraries. Not allocating enough space for PLT relocs results in ld writing outside of the buffer.
