The l Command l The l command disassembles instructions from memory. Format The format for the l command is: l [-bctT] [adr [cnt]] where: -b lists only branches. -c lists only calls. -t lists the trace buffer. -T assume TinyRISC (MIPS16) instructions. 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 EPC register and is output to the more command. Functional Description The l command disassembles the memory contents, starting either at the EPC 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 determines whether the Monitor displays hardware or software register names. Hardware register names are simply $0 through $31. Software registers are defined by the MIPS software conventions. Set regstyle to "hw" for hardware register names. Set regstyle to "sw" for software register names. Examples illustrating the use of the l command follow. PMON> set regstyle sw Normally the default.
