This option prints image information in text format. You can decode an ELF image or ELF object file using this option.
If you do not specify a code output format, --text is
assumed. That is, you can specify one or more options without having
to specify --text. For example, fromelf
-a is the same as fromelf --text -a.
If you specify a code output format, such as --bin,
then any --text options are ignored.
If destination--output option, or --output is
not specified, the information is displayed on stdout.
Syntax
--text [options]
Where options
-aPrints the global and static data addresses (including addresses for structure and union contents).
This option can only be used on files containing debug information. If no debug information is present, a warning is displayed.
Use the
--selectoption to output a subset of the data addresses.If you want to view the data addresses of arrays, expanded both inside and outside structures, use the
--expandarraysoption with this text category.-cThis option disassembles code, alongside a dump of the original binary data being disassembled and the addresses of the instructions.
Note
Unlike
--disassemble, the disassembly cannot be input to the assembler.-dPrints contents of the data sections.
-eDecodes exception table information for objects. Use with
-cwhen disassembling images.-gPrints debug information.
-rPrints relocation information.
-sPrints the symbol and versioning tables.
-tPrints the string tables.
-vPrints detailed information on each segment and section header of the image.
-wEliminates line wrapping.
-yPrints dynamic segment contents.
-zPrints the code and data sizes.
These options are only recognized in text mode.
The following examples show how to use --text:
To produce a plain text output file that contains the disassembled version of an ELF image and the symbol table, enter:
fromelf --text -c -s --output=outfile.lst infile.axfTo list to
stdoutall the global and static data variables and all the structure field addresses, enter:fromelf -a --select=* infile.axfTo produce a text file containing all of the structure addresses in
inputfile.axfbut none of the global or static data variable information, enter:fromelf --text -a --select=*.* --output=structaddress.txt infile.axfTo produce a text file containing addresses of the nested structures only, enter:
fromelf --text -a --select=*.*.* --output=structaddress.txt infile.axfTo produce a text file containing all of the global or static data variable information in
inputfile.axfbut none of the structure addresses, enter:fromelf --text -a --select=*,~*.* --output=structaddress.txt infile.axf
