NAME [Toc] [Back]
odump - dump information contained in SOM object files
SYNOPSIS [Toc] [Back]
odump [-option...] file...
DESCRIPTION [Toc] [Back]
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 [Toc] [Back]
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:
V T B -Option Description
- - - -all Print all information
V - - -auxheader Print SOM auxilary headers
V - - -auxunwind Print the stack auxiliary unwind table

RETURN VALUE [Toc] [Back]
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.

Environment Variables
The following variable affects the execution of odump:
Hewlett-Packard Company - 3 - HP-UX 11i Version 2: Sep 2004
odump(1) odump(1)
PA-RISC System Only
SHLIB_PATH A colon separated list of path names used to search
for shared libraries. Used by -sllibsearch and
-sllibloadlist options.
EXAMPLES [Toc] [Back]
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 $DEBUG$
