Target Milestone: ---
This one is mine, started with r249903:
$ cat c11-atomic-1.c
void a (_Atomic volatile int b) { b; }
$ gcc c11-atomic-1.c -c -fsanitize=address
c11-atomic-1.c: In function ‘a’:
c11-atomic-1.c:1:6: error: invalid rhs for gimple memory store
void a (_Atomic volatile int b) { b; }
^
b
b
# .MEM_32 = VDEF <.MEM_3(D)>
b ={v} b;
during GIMPLE pass: sanopt
