11.4 Invoking the Strip Utility

The strip utility, armstrip, removes symbol table and debugging information from object and executable files. To invoke the strip utility, enter the following:

armstrip [-p] input filename [input filename]
armstrip is the command that invokes the strip utility.
input filename is an object file (.obj) or an executable file (.out).
options identifies the strip utility options you want to use. Options are not case sensitive and can appear anywhere on the command line following the invocation. Precede each option with a hyphen (-). The strip utility option is as follows:
--help (-h) displays help information.
--outfile (-o)filename writes the stripped output to filename.
--postlink (-p) removes all information not required for execution. This option causes more information to be removed than the default behavior, but the object file is left in a state that cannot be linked. This option should be used only with executable (.out) files.
--rom Strip readonly sections and segments.
When the strip utility is invoked without the -o option, the input object files are replaced with the stripped version.
