5 Pseudo-Instruction Set

In addition to the PA-RISC instruction set, which is described in

PA-RISC 1.1 Architecture and Instruction Set Reference Manual and

PA-RISC 2.0 Architecture, the Assembler provides a number of

pseudo-instructions that perform commonly used forms of the basic

instructions. These pseudo-instructions are listed with their

standard-instruction format in Table 5-1 on page 120.

NOTE When coding branch instructions, including those with nulliﬁcation

speciﬁed, pay attention to the instruction that follows the branch in the

source code. All branch instructions consider this following instruction to

be in their delay slot. You can use a NOP pseudo-instruction to ﬁll the

delay slot when there is no other useful work to be performed. This delay

slot is usually executed.
