Title:
ARM/Neon: vcvt rounding error
Status in QEMU:
Fix Released
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?
