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)), ^ scripts/gcc-plugins/arm_ssp_per_task_plugin.c: In function ‘unsigned int arm_pertask_ssp_rtl_execute()’: scripts/gcc-plugins/arm_ssp_per_task_plugin.c:39:20: error: ‘gen_rtx_SET’ was not declared in this scope emit_insn_before(gen_rtx_SET
