dis - Disassemble an object file
As shipped in IRIX 6.5.5. Last changed in IRIX 6.5.5.
NAME dis - Disassemble an object file SYNOPSIS dis [ options ] file IMPLEMENTATION IRIX systems DESCRIPTION dis disassembles object files into machine instructions. The following options are accepted: -b beginaddress Disassemble starting at the given address. The address can be in decimal, octal (with a leading 0), or hexadecimal (with a leading 0x). -d "section" Disassemble the named section as data, printing the offset from the beginning of the section. -C Demangle C++ names. -D section Disassemble the named section as data, printing the actual address of the data. -e endaddress Disassembly stops at the given address. The address can be in decimal, octal (with a leading 0), or hexadecimal (with a leading 0x). -F function Disassemble the named function only in each object file specified on the command line. This option may be specified multiple times on the command line. -f Prefixes the line number on disassembly lines with the source file basename. -h Substitute the general register names for the software register names in the output. -H Remove the leading source line, leaving hex value and the instructions. -i Remove the leading source line and hexadecimal value of disassembly, leaving only the instructions. -I directory Use the directory to help find the source code. -l string Disassemble the archive file specified by string. For example, dis -l x would add usr/lib/libx.a to the files to be disassembled. -L Look up source labels for subsequent printing. This option works only if the file was compiled with debugging information. -o Print addresses and contents in octal. The default is hexadecimal. -p "function" The same meaning as -F function -pixie For pixie(1)d files, display original and pixified instructions intermixed with source. This is the default with pixified files, so this option obsolete and will eventually be removed. -s Attempts to print j, jal target names. Not very relevant since with PIC code j, jal are little used. This is the default unless the -svr4 option is specified. -svr4 Print using svr4 output format. This means (if no other options given) no externals are named (when loading data off of the $gp register). -S Display source code intermixed with the assembly code. There is no guarantee that the source code displayed is the source code used to compile the function, since dis simply looks for a source file starting with name/path given in the object and continuing by looking in directories specified with -I (if any) and accepts the first appropriately-named file it finds as the source file. If -S is repeated on the command line dis will, in addition, name the source file involved (with whatever path was used to acess the file), as in the example "Skipping source listing to line 10 of /b/t.c...". -T Trace flag is for debugging of the disassembler itself. -t section Disassemble the named section as a text section. -v Attempts to print the names of inlined functions where the function is inlined. The information about inlines is not always present in the debug information, so this option will not always produce the inlined function names. -V Print the version of dis being executed. -w Attempts to print source information (names of user variables involved) after (to the right of) assembly codes. This option comes into effect only if -s is also specified, but does not imply -s. (But recall from above that -s is on by default unless -svr4 is specified, so -w is effective by itself unless -svr4 was specified.) -x Prints offsets and constants in instructions as hex numbers. The default is to print instruction offsets and constants as decimal. If the -d, -D or -t options are specified, only those named sections from each user-supplied filename will be disassembled. Otherwise, all sections containing text will be disassembled. FILES /usr/bin/dis SEE ALSO This man page is available only online.
