Syntax

Predicate Register 

Remarks

A predicate register is supported by the following versions:

Pixel shader versions	1_1	1_2	1_3	1_4	2_0	2_sw	2_x	3_0	3_sw
predicate register							x	x	x

Here are the register properties.

Register type	Count	R/W	# Read ports	# Reads/inst	Dimension	RelAddr	Defaults	Requires DCL
Predicate(p)	1	R/W	1	1	4	N/A	None	N

The predicate register can be modified with setp. There are no default values for this register; an application needs to set the register before it is used.
