[Qemu-devel] [PATCH 0/3] target-ppc: improve FPU emulation

[Aurelien Jarno]

The PowerPC CPU has a lot more precise FPU exception than the IEEE754
specifications. 7 independant exceptions corresponding to the invalid
exception IEEE754. They are currently not implemented in softfloat code,
though they are detected to compute the result, that's why the target-ppc
code checks for the operands before calling the softfloat code.

This patch series fixes some issues with the FPU emulation, though the
long term solution is to implement the various flags in the softfloat 
code, and rely to compute the result.

Aurelien Jarno (3):
  target-ppc: remove PRECISE_EMULATION define
  target-ppc: fix default qNaN
  target-ppc: fix sNaN propagation
