I bisected the failure for all but the IEEE6 test to: commit 602f6e42cfbfe9278be34e9b91d2ceb695837e02 Author: Peter Maydell <peter.mayd...@linaro.org> Date: Thu Feb 28 10:55:16 2019 +0000
target/arm: Use MVFR1 feature bits to gate A32/T32 FP16 instructions Instead of gating the A32/T32 FP16 conversion instructions on the ARM_FEATURE_VFP_FP16 flag, switch to our new approach of looking at ID register bits. In this case MVFR1 fields FPHP and SIMDHP indicate the presence of these insns. This change doesn't alter behaviour for any of our CPUs.

I'm attaching a tarball containing several GCC tests (binaries), needed shared libs, and a short script to run all the tests. All tests used to pass w/o error, but with a recent qemu, all of them make qemu crash. This was noticed with GCC master configured with --target arm-none-linux-gnueabihf --with-cpu cortex-a57 --with-fpu crypto-neon-fp-armv8 Thanks To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1836078/+subscriptions
