Peter Maydell - Aug. 7, 2012, 1:51 p.m.
Move the DUMP_FPU and DUMP_CCOP flags for cpu_dump_state() from being
x86-specific flags to being generic ones. This allows us to drop some
TARGET_I386 ifdefs in various places, and means that we can (potentially)
be more consistent across architectures about which monitor commands or
debug abort printouts include FPU register contents and info about
QEMU's condition-code optimisations.
