ostrip - Reduce the size of object files
ostrip [options] file...
The following options are supported by the ostrip command:
-c Removes the .comment section of a linked image.
-g Removes unreferenced symbols and unused type information from the sym-
bol tables of a pre-link .o file. This results in a smaller on-disk
executable file. If .o files modified with this option are subsequently
linked, ostrip -m should be run on the linked image.
-j [image.stb] image
Joins together two files that were previously split by the -t option
into a symbol table file (image.stb) and a stripped image file (image).
-m Removes unreferenced symbols and unused type information for the symbol
tables of a post-link executable file. This results in a smaller on-
disk executable file. The symbol table still contains all information
required for debugging.
-r or -R
Decompresses the output of ostrip. This option is provided for cases in
which the input file is compressed in ALPHAMAGICZ format.
-s Removes the symbol table and any strippable subsections of the .comment
section. (Performs the same operations as the strip command.)
-t [image.stb] image
Splits an image file (image) into a symbol table file (image.stb) and a
stripped image file (image). The symbol table file will contain a
checksum of the stripped image.
-V Displays the version of the ostrip command.
-x Produces a reduced symbol table by removing local information. Also
deletes any locally strippable subsections of the .comment section.
(Performs the same operations as the ld -x command.)
-z or -Z
Compresses the output of ostrip into ALPHAMAGICZ format.
The ostrip command reduces the components of any object file based on the
options that are specified. It is designed to work with any object file,
that is, .o files, image files, and shared object files. It does not work
with .a (archive) files.
1. The following command strips the local symbol table and converts the
object file into ALPHAMAGICZ format:
ostrip -x -Z obj.o
2. The following command produces the symbol table file osize_mm.stb and
the stripped image file osize.mm:
ostrip -t osize.mm
3. The following command joins the symbol table file osize_mm.stb to
ostrip -j osize.mm
Commands: strip(1), ld(1), mcs(1), objZ(1)
