NAME

dis - object code disassembler

SYNOPSIS

dis [-onqCLV] [-d sec] [-D sec] [-F function]
[-l string] [-t sec] file...

DESCRIPTION

The dis command produces an assembly language listing of file, which can
be an object file or an archive of object files. The listing includes
assembly statements and an octal or hexadecimal representation of the
binary that produced those statements.

OPTIONS

Options are interpreted by the disassembler and can be specified in any
order.


The following options are supported:

-C
Displays demangled symbol names in the disassembly.


-d sec
Disassembles the named section as data, printing the
offset of the data from the beginning of the section.


-D sec
Disassembles the named section as data, printing the
actual address of the data.


-F function
Disassembles only the named function in each object file
specified on the command line. The -F option can be
specified multiple times on the command line.


-l string
Disassembles the archive file specified by string. For
example, one would issue the command dis -l x -l z to
disassemble libx.a and libz.a, which are assumed to be in
LIBDIR.

This option is obsolete and might be removed in a future
release of Solaris.


-L
Invokes a lookup of C-language source labels in the symbol
table for subsequent writing to standard output.

This option is obsolete and might be removed in a future
release of Solaris.


-n
Displays all addresses numerically. Addresses are
displayed using symbolic names by default.


-o
Prints numbers in octal. The default is hexadecimal.


-q
Quiet mode. Does not print any headers or function entry
labels.


-t sec
Disassembles the named section as text.


-V
Prints, on standard error, the version number of the
disassembler being executed.

This option is obsolete and might be removed in a future
release of Solaris.


If the -d, -D, or -t options are specified, only those named sections
from each user-supplied file is disassembled. Otherwise, all sections
containing text is disassembled.


On output, a number enclosed in brackets at the beginning of a line, such
as [5], indicates that the break-pointable line number starts with the
following instruction. These line numbers is printed only if the file was
compiled with additional debugging information.

OPERANDS

The following operand is supported:

file
A path name of an object file or an archive (see ar(1)) of object
files.

ENVIRONMENT VARIABLES

See environ(7) for descriptions of the following environment variables
that affect the execution of dis: LC_CTYPE, LC_MESSAGES, and NLSPATH.

LIBDIR
If this environment variable contains a value, use this as the
path to search for the library. If the variable contains a null
value, or is not set, it defaults to searching for the library
under /usr/lib.

EXIT STATUS

The following exit values are returned:

0
Successful completion.


>0
An error occurred.

FILES

/usr/lib
default LIBDIR

ATTRIBUTES
