This series is now just the ARM bits and expects to have the V4 softfloat patches as a prerequisite: https://lists.nongnu.org/archive/html/qemu-devel/2018-02/msg01330.html Alternatively you can grab the full tree from: https://github.com/stsquad/qemu/tree/arm-fp16-v2 I've tested with the following RISU test binaries: http://people.linaro.org/~alex.bennee/testcases/arm64.risu/testcases.armv8.2_hp.tar.xz And of course I ran the original RISU tests with: -cpu any,fp16=off But I guess we really just need to carefully regenerate the testcases to not include UNDEF's which get added with future revisions of the specification. Anyway please review.
