I was referring more to the front-end aspects here. Let's say we have:
__kernel void foo() {
float privateBuffer[8];
__local float localBuffer[8];
}
What mechanisms, other than address spaces, can we use to tell the X86
back-end that privateBuffer is private to the thread, and localBuffer is
shared among all threads in a work-group?
