From: Benjamin Gray Date: Wed, 17 Apr 2024 11:23:17 +0000 (+1000) Subject: selftests/powerpc/dexcr: Add -no-pie to hashchk tests X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d7228a58d9438d6f219dc7f33eab0d1980b3bd2f;p=linux.git selftests/powerpc/dexcr: Add -no-pie to hashchk tests 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.
