Doesn't work for me, either: [EMAIL PROTECTED]:/home/axboe $ ./a cvttps2dq_1 ... not ok result0.sd[0] = 0 (expected 12) result0.sd[1] = 0 (expected 56) result0.sd[2] = 0 (expected 43) result0.sd[3] = 0 (expected 87) cvttps2dq_2 ... not ok result0.sd[0] = 0 (expected 12) result0.sd[1] = 0 (expected 56) result0.sd[2] = 0 (expected 43) result0.sd[3] = 0 (expected 87) movdq2q_1 ... not ok result0.uq[0] = 240518168588 (expected 5124095577148911) movq2dq_1 ... not ok result0.uq[0] = 0 (expected 5124095577148911) result0.uq[1] = 0 (expected 0) [EMAIL PROTECTED]:/home/axboe $ ./a Segmentation fault Varies between the two. Compiling without -O2 makes the last two suceed, the others still not. This CPU has sse2. -- Jens Axboe _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
