NAME

dis − SPARC disassembler

SYNOPSIS

dis  [ -o ]  [ -g ]  [ -V ]  [ -F function ] file [ file . . . ]

DESCRITPION

dis disassembles SPARC object code into assembly language. 

OPTIONS

-o Print all numeric values in octal.  Default is hex. 

-V Print dis version number. 

-F function
Disassemble only the named function.  function is a function in one of the file parameters.  When file has been run through strip(1), the -F option will not work.  More than one -F option may be specified. 

-g Tell dis that file was compiled with -g and to use that additional symbol table information. 

EXAMPLE

An example output from dis is shown below.
