OpenCL: __local semantics

I am just wondering what is the semantic of the following kernel

#define T float
__kernel foo(){
    __local T bar[32];
    __local T a;
}

is bar/a shared between a work-group or every work-item will create a separate copy of bar/a?

They are both shared between the work-group, so there will only be one copy of bar and a per workgroup.
