Unlike the memory case, where "the destination operand receives a write cycle without regard to the result of the comparison", rm must not be touched altogether if the write fails, including not zero-extending it on 64-bit processors. This is not how the movcond currently works, because it is always followed by a gen_op_mov_reg_v to rm. To fix it, introduce a new function that is similar to gen_op_mov_reg_v but writes to a TCG temporary. Considering that gen_extu(ot, oldv) is not needed in the memory case either, the two cases for register and memory destinations are different enough that one might as well fuse the two "if (mod == 3)" into one. So do that too.

README
This directory contains various interesting guest programs for regression testing. Tests are either multi-arch, meaning they can be built for all guest architectures that support linux-user executable, or they are architecture specific. CRIS ==== The testsuite for CRIS is in tests/tcg/cris. You can run it with "make test-cris".
