I updated my QEMU git tree such that it includes commit bd49e6027cbc207c, and the test now passes.
Thanks for the prompt fix! ** Changed in: qemu Status: New => Fix Committed -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1761401 Title: ARM/Neon: vcvt rounding error Status in QEMU: Fix Committed Bug description: Hello, While using QEMU commit 47d3b60858d90ac8a0cc3a72af7f95c96781125a (March 28, 2018), I've noticed failures in one of the GCC ARM/Neon tests. 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?
