Always enable precise emulation when softfloat is used

The patch below changes the way to enable softfloat on the PPC target. It
is now enabled when softfloat is used. The rationale behind this change
is that persons who want precise emulation prefer precision over emulation...

Math functions helper for CONFIG_SOFTFLOAT=yes

The patch below adds isfinite() and isnormal() functions which can
work with float64 type, used when CONFIG_SOFTFLOAT=yes.

Use float32/64 instead of float/double

The patch below uses the float32 and float64 types instead of the float
and double types in the PPC code. This doesn't change anything when
using softfloat-native as the types are the same, but that helps
compiling the PPC target with softfloat....

mtfsf: fix FPSCR_VX and FPSCR_FEX computation

The patch below fixes the computation of FPSCR_VX and FPSCR_FEX when
using the mtfsf instruction. As stated in the PowerPC manual the mtfsf
instruction can't alter those bit, and thus it should always be
computed....

Remove not-needed-anymore ppcemb-linux-user target.
Keep ppcemb-softmmu target, which provides 1kB pages support

PowerPC 601 need specific callbacks for its BATs setup.
Implement PowerPC 601 HID0 register, needed for little-endian mode support.
As a consequence, we need to merge hflags coming from MSR with other ones.
Use little-endian mode from hflags instead of MSR during code translation....
faadf50e 11/03/2007 03:37 pm j_mayer PowerPC MMU and exception fixes:
  • PowerPC 601 (and probably POWER/POWER2) uses a different BAT format than
    later PowerPC implementation.
  • Bugfix in BATs check: must not stop after 4 BATs when more are provided.
  • Enable POWER 'rac' instruction.
  • Fix exception prefix for all supported PowerPC implementations....
