The following table describes how TotalView treats each general register, and the actions you can take with each register.

Register	Description	Data Type	Edit	Dive	Specify in Expression

SP	Stack pointer	$int/$long	yes	yes	$sp
RTOC	TOC pointer	$int/$long	yes	yes	$rtoc
R3 - R31	General registers 3 - 31	$int/$long	yes	yes	$r3 - $r31
INUM		$int/$long	yes	no	$inum
PC	Program counter	$code[]	no	yes	$pc
SRR1	Machine status save/restore register	$int/$long	yes	no	$srr1
LR	Link register	$code[]	yes	no	$lr
CTR	Counter register	$int/$long	yes	no	$ctr
CR	Condition register (see below)	$int/$long	yes	no	$cr
XER	Integer exception register (see below)	$int/$long	yes	no	$xer
DAR	Data address register	$int/$long	yes	no	$dar
MQ	MQ register	$int/$long	yes	no	$mq
MSR	Machine state register	$int/$long	yes	no	$msr
SEG0 - SEG9	Segment registers 0 - 9	$int/$long	yes	no	$seg0 - $seg9

SAD2	SS_ADDR 2	$int/$long	yes	no	$sad2
SCD1	SS_CODE 1	$int/$long	yes	no	$scd1
SCD2	SS_CODE 2	$int/$long	yes	no	$scd2
TID		$int/$long	yes	no

CR Register

TotalView writes information for each of the eight condition sets, appending a a >, <, or = symbol. For example, if the summary overflow (0x1) bit is set, TotalView might display the following:

0x22424444 (574768196) (0=,1=,2>,3=,4>,5>,6>,7>)

XER Register

Depending upon what was set, TotalView can display up to five kinds of information, as follows:

STD:0x%02x

The string terminator character (bits 25-31)

SL:%d

The string length field (bits 16-23)

Displayed if the summary overflow bit is set (bit 0)

Displayed if the overflow bit is set (bit 1)

Displayed if the carry bit is set (bit 2)

For example:

0x20000002 (536870914) (STD:0x00,SL:2,CA)
