From 239054f48439c18b93e1a70ff29dbcb0c4742cff Mon Sep 17 00:00:00 2001 From: Tommaso Marinelli Date: Sun, 6 Oct 2019 21:12:06 +0200 Subject: arch: Drop sysctl support if built against glibc Since glibc 2.30 the sysctl() function has been declared deprecated and it will be deleted in future versions. This patch removes the support for the sysctl system call in SE mode (which is currently serviced calling the sysctl() function) if gem5 is built against glibc, keeping it with other libc implementations, as a temporary measure to prevent the generation of a compilation error. Note that this system call in gem5 is only supported for the arm/freebsd architecture.
