From 80ffc7398b8302b2d54d783d8349e54d877a4250 Mon Sep 17 00:00:00 2001 From: Brooks Davis Date: Mon, 22 Apr 2024 20:13:35 +0100 Subject: [PATCH] libsys/arm: make vfork less of an outlier Following the pattern of other architectures, make __sys_vfork the main symbol and _vfork and vfork weak aliases. This avoids the need to special case vfork in the generated list of symbols.
