From 0de175b8d6722cca2221bbb52772f975058ac183 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Mon, 8 Jul 2019 06:21:05 +0000 Subject: [PATCH] Make guality.h handle Yama restricted ptrace mode guality.exp is silently skipped on Linux systems with kernel.yama.ptrace_scope=1 because gdb fails to attach to the sanity check test. This patch uses PR_SET_PTRACER (where available) to avoid this. prctl was apparently added in Linux 2.1.57, so I don't think we need any tests other than __linux for the #include. 2019-07-08 Richard Sandiford gcc/testsuite/ * gcc.dg/guality/guality.h: Include on Linux targets. (main): Use PR_SET_PTRACER where available.
