PowerPC: Optimized isinf/isinff for POWER8
|
||
|
|
|
||
|
|
This patch add a optimized isinf/isinff implementation for POWER8
|
||
|
|
using the new Move From VSR Doubleword instruction to gains some
|
||
|
|
cycles from FP to GRP register move.

PowerPC: Fix little endian enconding for mfvsrd
|
||
|
|
|
||
|
|
This patch fixes the MFVSRD_R3_V1 macro that encodes 'mfvsrd r3,vs1'
|
||
|
|
(to support old binutils) for little endian.
