The u command displays an assembly translation of the specified program code in memory.

Do not confuse this command with the ~u (Unfreeze Thread) command.

Syntax

u[b] Range 
u[b] Address
u[b] 

Parameters

Range

Specifies the memory range that contains the instructions to disassemble. For more information about the syntax, see Address and Address Range Syntax. If you use the b flag, you must specify Range by using the "Address LLength" syntax, not the "Address1 Address2" syntax.

Address

Specifies the beginning of the memory range to disassemble. Eight instructions (on an x86-based processor) or nine instructions (on an Itanium-based processor) are unassembled. For more information about the syntax, see Address and Address Range Syntax.

b

Determines the memory range to disassemble by counting backward. If ub Address is used, the disassembled range will be the eight or nine byte range ending with Address. If a range is specifed using the syntax ub Address LLength, the disassembled range will be the range of the specified length ending at Address.

Environment

Comments

If you do not specify a parameter for the u command, the disassembly begins at the current address and extends eight instructions (on an x86-based processor) or nine instructions (on an Itanium-based processor). When you use ub without a parameter, the disassembly includes the eight or nine instructions before the current address.

Do not confuse this command with the up (Unassemble from Physical Memory). The u command disassembles only virtual memory, while the up command disassembles only physical memory.
