Fix descriptions (disassembly) for movss instructions in x86 tester #1230

Closed Trust04zh closed 1 year ago

Trust04zh commented 1 year ago

descriptions for movss instructions in x86 tester do not match the real instructions, this impacts the debugging information but does not undermine the effectiveness of the testing.
