[Qemu-devel] [PATCH v2 00/24] A64 decoder patchset 6: rest of floating point

[Peter Maydell]

This patchset completes the FP emulation, leaving us with only
Neon (and CRC32) to go to complete the user-mode emulation.
Most of this is fixing issues and adding new features to softfloat.
(As usual, all Linaro authored softfloat patches are licensed under
either softfloat-2a or softfloat-2b, at your option.)
We need Tom Musta's softfloat patches too, so I have included them
here (updated to the latest versions with the issues fixed).

Changes v1->v2:
 * updated versions of Tom Musta's patches "Fix float64_to_uint64"
   and "Add float32_to_uint64"
 * 16 bit int-to-float fns now take exact-width types
 * new patch: "softfloat: Make the int-to-float functions take
   exact-width types", to make the other int-to-float functions
   consistent
 * "Prepare VFP_CONV_FIX helpers for A64 uses" now also drops the
   cast in the int_to_float call, since the above changes make it
   unnecessary
 * use 32 bit type as the intermediate when doing float-to-16-bit-int
   conversions
 * new patch: "softfloat: Refactor code handling various rounding modes"
   which is a pure refactoring of the rounding mode code to
   consistently use switches; this makes the "ties-away" support
   patch nicer and ends up with more readable code

Alex: we should coordinate about whether these softfloat patches
should go through my tree or yours, otherwise there's going to be
a clash...

thanks
