However, this actually needs to be tested on a SPAR= C T1 as both T2 and T4 have their own implementation that is being used. Testing= on a T4 will therefore not invoke this particular code unless you modify the ker= nel in head_64.S to employ the Niagara 1 code on Niagara 4. Do you happen to have a SPARC T1?
