Examining and Changing Register Values

Memory and Disassembling Code” on page 85). If $regstyle is set to 0, then

dbx uses the alternate form of the register name (for example, “zero” instead

of “r0,” and “t1” instead of “r9”); if $regstyle is anything other than 0, the

machine names are used (“r0” through “r31”).

Printing Register Values

Use the printregs command to print the values stored in all registers.

The base in which the register values are displayed depends on the values of

the dbx variables $octints and $hexints. By default, dbx prints the register

values in decimal. You can set the output base to octal by setting the dbx

variable $octints to a nonzero value. You can set the output base to

hexadecimal by setting the dbx variable $hexints to a nonzero value. If you

set both $octints and $hexints to nonzero values, $hexints takes precedence.

To examine the register values in hexadecimal, enter the following:

(dbx) set $hexints = 1
