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.
