[PATCH 00/72] Convert floatx80 and float128 to FloatParts |
Date: |

Reorg everything using QEMU_GENERIC and multiple inclusion to
reduce the amount of code duplication between the formats.
The use of QEMU_GENERIC means that we need to use pointers instead
of structures, which means that even the smaller float formats
need rearranging.
I've carried it through to completion within fpu/, so that we don't
have (much) of the legacy code remaining. There is some floatx80
stuff in target/m68k and target/i386 that's still hanging around.
