[Qemu-devel] [PATCH v2 2/3] ARM: Set softfloat cumulative exc flags from correct FPSCR bits

[Peter Maydell <peter.maydell@linaro.org>]

When handling a write to the ARM FPSCR, set the softfloat cumulative
exception flags from the cumulative flags in the FPSCR, not the
exception-enable bits. Also don't apply a mask: vfp_exceptbits_to_host
will only look at the correct bits anyway.
