- .PD 0
- .IP "fB--wildcardfR" 4
- .IX Item "--wildcard"
- .PD
- Permit regular expressions in fIsymbolnamefRs used in other command
- line options. The question mark (?), asterisk (*), backslash (e) and
- square brackets ([]) operators can be used anywhere in the symbol
- name. If the first character of the symbol name is the exclamation
- point (!) then the sense of the switch is reversed for that symbol.
- For example:
- .Sp
- .Vb 1
- & -w -K !foo -K fo*
- .Ve
- .Sp
- would cause strip to only keep symbols that start with the letters
- ``fo'', but to discard the symbol ``foo''.
- .IP "fB-xfR" 4
- .IX Item "-x"
- .PD 0
- .IP "fB--discard-allfR" 4
- .IX Item "--discard-all"

- .IP "fB-XfR" 4
- .IX Item "-X"
- .PD 0
- .IP "fB--discard-localsfR" 4
- .IX Item "--discard-locals"
- .PD
- Remove compiler-generated local symbols.
- (These usually start with fBLfR or fB.fR.)
- .IP "fB--only-keep-debugfR" 4
- .IX Item "--only-keep-debug"
- Strip a file, removing any sections that would be stripped by
- &fB--strip-debugfR and leaving the debugging sections.
- .Sp
- The intention is that this option will be used in conjunction with
- &fB--add-gnu-debuglinkfR to create a two part executable. One a
- stripped binary which will occupy less space in s-1RAMs0 and in a
- distribution and the second a debugging information file which is only
- needed if debugging abilities are required. The suggested procedure
- to create these files is as follows:
- .RS 4
- .IP "1.<Link the executable as normal. Assuming that is is called>" 4
- .IX Item "1.<Link the executable as normal. Assuming that is is called>"
- &f(CW*(C`foo*(C'fR then...
- .ie n .IP "1.<Run ""objcopy --only-keep-debug foo foo.dbg"" to>" 4
- .el .IP "1.<Run f(CWobjcopy --only-keep-debug foo foo.dbgfR to>" 4
- .IX Item "1.<Run objcopy --only-keep-debug foo foo.dbg to>"
- create a file containing the debugging info.
- .ie n .IP "1.<Run ""objcopy --strip-debug foo"" to create a>" 4
- .el .IP "1.<Run f(CWobjcopy --strip-debug foofR to create a>" 4
- .IX Item "1.<Run objcopy --strip-debug foo to create a>"
- stripped executable.
- .ie n .IP "1.<Run ""objcopy --add-gnu-debuglink=foo.dbg foo"">" 4
- .el .IP "1.<Run f(CWobjcopy --add-gnu-debuglink=foo.dbg foofR>" 4
- .IX Item "1.<Run objcopy --add-gnu-debuglink=foo.dbg foo>"
- to add a link to the debugging info into the stripped executable.
- .RE
- .RS 4
- .Sp
- Note - the choice of f(CW*(C`.dbg*(C'fR as an extension for the debug info
- file is arbitrary. Also the f(CW*(C`--only-keep-debug*(C'fR step is
- optional. You could instead do this:
- .IP "1.<Link the executable as normal.>" 4
- .IX Item "1.<Link the executable as normal.>"
- .PD 0
- .ie n .IP "1.<Copy ""foo""fR to f(CW""foo.full"">" 4
- .el .IP "1.<Copy f(CWfoofR to f(CWfoo.fullfR>" 4
- .IX Item "1.<Copy foo to foo.full>"
- .ie n .IP "1.<Run ""strip --strip-debug foo"">" 4
- .el .IP "1.<Run f(CWstrip --strip-debug foofR>" 4
- .IX Item "1.<Run strip --strip-debug foo>"
- .ie n .IP "1.<Run ""objcopy --add-gnu-debuglink=foo.full foo"">" 4
- .el .IP "1.<Run f(CWobjcopy --add-gnu-debuglink=foo.full foofR>" 4
- .IX Item "1.<Run objcopy --add-gnu-debuglink=foo.full foo>"
- .RE
- .RS 4
- .PD
- .Sp
- ie the file pointed to by the fB--add-gnu-debuglinkfR can be the
- full executable. It does not have to be a file created by the
- &fB--only-keep-debugfR switch.
- .RE
- .IP "fB-VfR" 4

- .IP "fB--versionfR" 4
