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This option is obsolete and might be removed in a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This option is obsolete and might be removed in a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This option is obsolete and might be removed in a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
