gcc-plugins: arm_ssp_per_task_plugin: Fix for older GCC < 6
commit 259799ea5a9aa099a267f3b99e1f7078bbaf5c5e upstream.
Use gen_rtx_set instead of gen_rtx_SET. The former is a wrapper macro
that handles the difference between GCC versions implementing
the latter.
This fixes the following error on my system with g++ 5.4.0 as the host
compiler
HOSTCXX -fPIC scripts/gcc-plugins/arm_ssp_per_task_plugin.o
scripts/gcc-plugins/arm_ssp_per_task_plugin.c:42:14: error: macro "gen_rtx_SET" requires 3 arguments, but only 2 given
mask)),
