            Bug ID: 86729
           Summary: address of vector element requested
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: zhonghao at pku dot org.cn
  Target Milestone: ---

gcc accepts the following code:

void a() {
 typedef float v4sf __attribute__ ((vector_size (16)));
 static v4sf q;
 float* r = &q[0];
}

clang rejects it:

clang code1.c 
code1.c:4:13: error: address of vector element requested
 float* r = &q[0];
            ^~~~~
1 error generated.


The error message of clang seems to be reasonable?
