[Qemu-devel] [PATCH 2/6] target/arm: Ignore float_flag_input_denormal from fp_status_f16

2018-08-10 Thread Richard Henderson
When FZ is set, input_denormal exceptions are recognized, but this does not happen with FZ16. The softfloat code has no way to distinguish these bits and will raise such exceptions into fp_status_f16.flags, so ignore them when computing the accumulated flags. Cc: qemu-sta...@nongnu.org (3.0.1)
