[Qemu-devel] [PATCH 00/22] 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. Note that two of these still have outstanding issues identified
in code review : see the notes in their commit messages (and I haven't
applied my signed-off-by line to them).

This patchset sits on top of the previous ones; you can find a git tree at

New Year's Resolution for 2014: avoid using the phrase "yeah,
sure, we can get that done by the end of the year".

thanks
