From 50b40d37fa7e659531b118c6d73119bf4b8939cf Mon Sep 17 00:00:00 2001 From: Benjamin Gray Date: Wed, 17 Apr 2024 21:23:17 +1000 Subject: [PATCH] selftests/powerpc/dexcr: Add -no-pie to hashchk tests BugLink: https://bugs.launchpad.net/bugs/2073603 [ Upstream commit d7228a58d9438d6f219dc7f33eab0d1980b3bd2f ] The hashchk tests want to verify that the hash key is changed over exec. It does so by calculating hashes at the same address across an exec. This is made simpler by disabling PIE functionality, so we can re-execute ourselves and be using the same addresses in the child. While -fno-pie is already added, -no-pie is also required.
