Constants ¶

const (
	ODynam   = 1 << 0
	OAddable = 1 << 1
)

const (
	V_CC = 1 << 0 // xCC (affect CR field 0 flags)
	V_V  = 1 << 1 // xV (affect SO and OV flags)
)

Many Power ISA arithmetic and logical instructions come in four standard variants. These bits let us map between variants.

const (
	LeftRdwr  uint32 = gc.LeftRead | gc.LeftWrite
	RightRdwr uint32 = gc.RightRead | gc.RightWrite
)

const (
	NREGVAR = 64 /* 32 general + 32 floating */
)

Variables ¶

var MAXWIDTH int64 = 1 << 50
