The PRECISE_EMULATION is "hardcoded" to one in target-ppc/exec.h and not something easily tunable. Remove it and non-precise emulation code as it doesn't make a noticeable difference in speed. People wanting speed improvement should use softfloat-native instead. Acked-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
