Hi @eugenis, I didn't understood your suggestion clearly.
I understand OVERFLOW() and NO_POISON() will have same definition.

In this revision, I initiialized arguments that start in param-tls and end outside of it upto till param-tls size, so they will match condition of OVERFLOW().
Without initialing, they will match NO_OVERFLOW in archs other than x86.

What will be functionality of PARTIAL_OVERFLOW(), and if you want to keep same test for all archs, than should we initialize overflow arguments ?
