2013-01-31target-mips: use DSP unions for binary DSP operatorsAurelien Jarno
This allow to reduce the number of macros. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2013-01-31target-mips: add unions to access DSP elementsAurelien Jarno
Instead of playing with bit shifting, add two unions (one for 32-bit values, one for 64-bit ones) to access all the DSP elements with the correct type. This make the code easier to read and less error prone, and allow GCC to vectorize the code in some cases.

2013-01-31target-mips: generate a reserved instruction exception on CPU without DSPAurelien Jarno
On CPU without DSP ASE support, a reserved instruction exception (instead of a DSP ASE sate disabled) should be generated. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2013-01-31target-mips: copy insn_flags in DisasContextAurelien Jarno
Copy insn_flags in DisasContext to avoid passing a CPUMIPSState pointer to subroutines, as suggested by Richard Henderson. Change subroutines to use this new field and remove the first argument. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2013-01-30qemu-pixman.h: Avoid mutual inclusion loop with console.hPeter Maydell
Remove an unnecessary mutual inclusion loop between qemu-pixman.h and console.h, since the former was only including the latter for 'PixelFormat*', which can be provided by typedefs.h. This requires a minor adjustment to the files which included qemu-pixman.h, since they were relying on it implicitly dragging in all of console.h.
