2012-10-04target-ppc: get rid of the HANDLE_NAN{1, 2, 3} macrosAurelien Jarno1-21/+0
We can finally get rid of the ugly HANDLE_NAN{1,2,3} macros. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-10-04target-ppc: use the softfloat float32_muladd functionAurelien Jarno1-43/+14
Use the new softfloat float32_muladd() function to implement the vmaddfp and vnmsubfp instructions. As a bonus we can get rid of the call to the HANDLE_NAN3 macro, as the NaN handling is directly done at the softfloat level.

2012-10-04target-ppc: use the softfloat min/max functionsAurelien Jarno1-21/+2
Use the new softfloat float32_min() and float32_max() to implement the vminfp and vmaxfp instructions. As a bonus we can get rid of the call to the HANDLE_NAN2 macro, as the NaN handling is directly done at the softfloat level.

2012-10-04target-ppc: simplify NaN propagation for vector functionsAurelien Jarno1-19/+7
Commit e024e881bb1a8b5085026589360d26ed97acdd64 provided a pickNaN() function for PowerPC, implementing the correct NaN propagation rules. Therefore there is no need to test the operands manually, we can rely on the softfloat code to do that.

2012-06-24ppc: Make hbrev table constBlue Swirl1-1/+1
Lookup table 'hbrev' is never written to, so add a 'const' qualifier. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-06-24ppc: Avoid AREG0 for integer and vector helpersBlue Swirl1-47/+73
Add an explicit CPUPPCState parameter instead of relying on AREG0.
