code that is candidate for object flattening optimization

gistfile1.cpp

// pgas pseudocode, borrowing syntax from Chapel and UPC

struct global_ptr_string {
  int len;
  global const char* str;
   
  global_ptr_string(...) { ... }
}

const global_ptr_string x(...);
on(10) {
  for (int i=0; x.str[i]!='\0'; i++) {
    printchar (x.str[i]) 
  }
  print ("\n")
}

ok updated with more const to make it easier.

anyway, shouldn't we be considering a SC for DRF model?

making it const should do the trick (assuming you can trust const, unlike in C++). ;)

sure, but you're proposing moving a load up, so you have to at least prove nothing in your on block modifies it between where you hoisted it.

this is exactly the kind of thing I remember wishing Chapel would do for me. That or just make const things available everywhere so I didn't have to worry about where they lived.
