NAME

odump — dump information contained in SOM object files

SYNOPSIS

odump [-option...] file...

DESCRIPTION

odump takes one or more 32-bit native code files (object files, shared and archive libraries, executables) and dumps information about them.

Note: odump skips non-SOM input files and issues a warning.

  • $ odump -all /usr/lib/pa20_64/libc.sl

    File is not a SOM, skipping: /usr/lib/pa20_64/libc.sl.

Options

Some odump options have additional support or provide additional information when used in combination with the modifier options:

V (VERIFY)

Indicate that the structure specified by its corresponding option is verified when run with the -verifyall option.

T (TITLES)

Provides additional output format information for the structure specified by its corresponding option when run with the -titles option.

B (VERBOSE)

Prints a more descriptive message for the structure specified by its corresponding option when run with the -verbose option.

The table below indicates the available support for each option.

odump recognizes the following options and their modifiers:

RETURN VALUE

odump exits with one of the following values:

0:

All input files were listed successfully.

>0:

odump aborted because errors occurred when accessing files. The following conditions cause an error:

  • Specified file not found.

  • User has no permission to read the directory.

  • Process could not get enough memory.

  • Invalid option specified.

EXTERNAL INFLUENCES

Environment Variables

The following variable affects the execution of odump:

SHLIB_PATH

A colon separated list of path names used to search for shared libraries. Used by -sllibsearch and -sllibloadlist options.

EXAMPLES

To see what compiler options and version an executable was compiled with:

$ odump -compunit a.out

To list the shared libraries (.sl) that a program loads, even if SHLIB_PATH is set:

$ odump -sllibload a.out

To see how much space a program needs in Quadrant 2 to hold the data, bss, stack, and other areas, look at the values in the som_exec_auxhdr:

$ odump -auxheader a.out

Auxiliary Header Record (HP-UX) for a.out: mandatory = 0 copy = 0 append = 0 ignore = 1 type = 4 length = 40 exec_tsize = 0x000023ec exec_tmem = 0x00001000 exec_tfile = 0x00002000 exec_dsize = 0x00001000 exec_dmem = 0x40001000 exec_dfile = 0x00005000 exec_bsize = 0x3bfff120 exec_entry = 0x000029c8 exec_flags = 0x00000004 exec_bfill = 0x00000000

To see if a program was built for debugging with -g and not for optimization with -O, look for a $DEBUG$ space (programs built for both show $PINFO$ instead of $DEBUG$):

$ odump -spaces a.out

Space dictionary for a.out: Ind LDPIT Sort Space Subspaces Ldr Fixups Init Ptrs Name 0 LD... 8 1 0 8 -1 0 0 1 $TEXT$ 1 LDP.. 16 0 8 9 -1 0 1 1 $PRIVATE$ 2 .DP.. 80 2 17 5 -1 0 -1 0 $DEBUG$
