[Qemu-devel] [PATCH 11/22] softfloat: Provide complete set of accessors for fp state |
Date: |

Tidy up the get/set accessors for the fp state to add missing ones
and make them all inline in softfloat.h rather than some inline and
some not.
Signed-off-by: Peter Maydell <address@hidden>

The specific one we want for A64 is to get the rounding mode,
but we might as well fill in the gaps.
