            Bug ID: 44770
           Summary: Library vectorization broken with new pass manager
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Loop Optimizer

$ cat veclib.c 
void foo(float *a) {
  for (int i = 0; i != 1024; ++i)
    a[i] = __builtin_expf(a[i]);
}

$ clang -O3 -S -o - veclib.c -fveclib=Accelerate
-fexperimental-new-pass-manager|grep vexpf
$ clang -O3 -S -o - veclib.c -fveclib=Accelerate |grep vexpf                    
        callq   vexpf
        callq   vexpf

The reason seems to be that InjectTLIMappings never runs.
