void* p1;
void* p2;
p2 = function(p1);
Do p1 and p2 alias? Note: function() is in a *.so file, no source available.
How many times do you have all of the source code available for analysis?
- gcp 15y agoI pointed out specifically that all source code is available exactly for this reason. The original claim was that "for Fortran this is expected" which isn't true at all in this condition. So aliasing information can't explain the performance difference.
