.ptr pseudo-op

Edit online

Purpose

Assembles expressions into consecutive pointer-size elements.

Syntax

Item Description
.ptr Expression[, Expression, ...]

Description

The .ptr pseudo-op assembles expressions into consecutive words in 32-bit mode and consecutive doublewords in 64-bit mode. The .ptr pseudo-op allows the same source code to be used in both 32 and 64-bit modes, and is most useful when the expression includes a relocatable reference. The .ptr pseudo-op is equivalent to the .long pseudo-op in 32-bit mode and the .llong pseudo-op in 64-bit mode.

Fullword alignment occurs as necessary, unless the current section is a DWARF section.

Parameters

Item Description
Expression An absolute expression.

Examples

The following example illustrates the use of the .ptr pseudo-op: 

       .extern             foo{RW]    
       .csect              mydata[RW]
       .ptr                foo[RW]       # Pointer to foo with appropriate relocation
                                         # 4 bytes in 32-bit mode
                                         # 8 bytes in 32-bit mode
