This option helps to protect your code in images and objects that are delivered to third parties. You can also use it to help reduce the size of the output image.
Restrictions--strip=option[,option,...]
Where option is one of:
allFor object modules, this option removes all debug, comments, notes and symbols from the ELF file. For executables, this option works the same as
--no_linkview.Note
Do not use the
--strip=alloption with SysV images.debugRemoves all debug sections from the ELF file.
commentRemoves the .comment section from the ELF file.
filesymbolsThe
STT_FILEsymbols are removed from the ELF file.localsymbolsThe effect of this option is different for images and object files.
For images, this option removes all local symbols, including mapping symbols, from the output symbol table.
For object files, this option:
Keeps mapping symbols and build attributes in the symbol table.
Removes those local symbols that can be removed without loss of functionality.
Symbols that cannot be removed, such as the targets for relocations, are kept. For these symbols, the names are removed. These are marked as
[Anonymous Symbol]in the fromelf --text output.
notesRemoves the .notes section from the ELF file.
pathnamesRemoves the path information from all symbols with type
STT_FILE. For example, anSTT_FILEsymbol with the nameC:\work\myobject.ois renamed tomyobject.o.Note
This option does not strip path names that are in the debug information.
symbolsThe effect of this option is different for images and object files.
For images, this option removes the complete symbol table, and all static symbols. If any of these static symbols are used as a static relocation target, then these relocations are also removed. In all cases,
STT_FILEsymbols are removed.For object files, this option:
Keeps mapping symbols and build attributes in the symbol table.
Removes those local symbols that can be removed without loss of functionality.
Symbols that cannot be removed, such as the targets for relocations, are kept. For these symbols, the names are removed. These are marked as
[Anonymous Symbol]in the fromelf --text output.
Note
Stripping the symbols, path names, or file symbols might make the file harder to debug.
To produce an output.axf file without
debug from the ELF file infile.axf originally
produced with debug, enter:
fromelf --strip=debug,symbols --elf --output=outfile.axf infile.axf
