selected by the \fB\-b\fP or \fB\-\-byte\fP option. The default is 4.
The interleave is ignored if neither \fB\-b\fP nor \fB\-\-byte\fP is given.
.TP
+.B \-p\fR, \fB\-\-preserve\-dates
+Set the access and modification dates of the output file to be the same
+as those of the input file.
+.TP
+.B \-\-debugging
+Convert debugging information, if possible. This is not the default
+because only certain debugging formats are supported, and the
+conversion process can be time consuming.

-Fill gaps between sections with \fIval\fP. This is done by increasing
+Fill gaps between sections with \fIval\fP. This operation applies to
+the \fIload address\fP (LMA) of the sections. It is done by increasing
the size of the section with the lower address, and filling in the extra
space created with \fIval\fP.

only works on file formats which can support sections with arbitrary
names.
.TP
+.B \-\-change\-leading\-char
+Some object file formats use special characters at the start of
+symbols. The most common such character is underscore, which compilers
+often add before every symbol. This option tells
+.B objcopy
+to change the leading character of every symbol when it converts
+between object file formats. If the object file formats use the same
+leading character, this option has no effect. Otherwise, it will add
+a character, or remove a character, or change a character, as
+appropriate.
+.TP
+.B \-\-remove\-leading\-char
+If the first character of a global symbol is a special symbol leading
+character used by the object file format, remove the character. The
+most common symbol leading character is underscore. This option will
+remove a leading underscore from all global symbols. This can be
+useful if you want to link together objects of different file formats
+with different conventions for symbol names. This is different from
+@code{--change-leading-char} because it always changes the symbol name
+when appropriate, regardless of the object file format of the output

+.B \-\-weaken
+Change all global symbols in the file to be weak.

.B \-v\fR, \fB\-\-verbose
Verbose output: list all object files modified. In the case of
archives, "\fBobjcopy \-V\fR" lists all members of the archive.
