Now I have to find why.
I don't really understand, because that is the part of the code (at least from the op point of view) that is almost unchanged. Looking at the code again and again I can't see any problem. Could you please try to find the values of T1 at the end of helper_ld_asi (adding a printf or using gdb). That may help us to understand what is the problem. -- .''`.
