The test passes on hardware, and with QEMU-2.11.0, so it looks like a recent regression. + +The test builds a vector of 4 float32 with "125.9" as value, then converts them to 4 uint32_t. +The expected result is 125, but we get 126 instead. + +Maybe it's just a matter of default rounding mode? + +Hi Christophe -- we think that commit bd49e6027cbc207c, now in master, should have fixed this bug. Could you retry your testcase with a QEMU build including that fix? + + +I updated my QEMU git tree such that it includes commit bd49e6027cbc207c, and the test now passes. + +Thanks for the prompt fix! + + |
