l

The l command disassembles instructions from memory.

Format

The format for the l command is:

l [-bct] [adr [cnt]]

where:

-b	lists only branches.
-c	lists only calls.
-t	lists the trace buffer.
adr	is the base address from which to disassemble instructions.
cnt	is the number of lines to disassemble.

When invoking this command with no options, disassembly starts at the address in the PC register and is output to the more command.

Functional Description

The l command disassembles the memory contents, starting either at the PC register's current value or at the specified address. The output of this command is passed to the more command, letting the user view one screenful of disassembled output at a time. Optionally, the user can specify a count value, which limits the number of disassembled lines to that number.

The regstyle Variable

The regstyle environment variable is an architecture dependent variable which determines whether the Monitor displays hardware or software register names. Hardware register names are simply r00 throughr31. Software registers are defined by the PowerPC software conventions

Examples illustrating the use of the l command follow.
This example are for the MIPS architecture but looks similar on other architectures,
