.SH DESCRIZIONE
.IX Intestazione DESCRIZIONE
\&\fBreadelf\fP displays information about one or more ELF format object
files.  The options control what particular information to display.
.PP
\&\fIelffile\fP... are the object files to be examined.  32\-bit and 64\-bit ELF
files are supported, as are archives containing ELF files.
.PP
This program performs a similar function to \fBobjdump\fP but it goes into more
detail and it exists independently of the BFD library, so if there is a bug
in BFD then readelf will not be affected.
.SH OPZIONI
.IX Intestazione OPZIONI
Le forme lunga e breve delle opzioni, qui mostrate come alternative, sono
equivalenti. Deve essere data almeno un'opzione tra \fB\-v\fP o \fB\-H\fP.

e \fB\-\-histogram\fP.
.Sp
Note \- this option does not enable \fB\-\-use\-dynamic\fP itself, so if that
option is not present on the command line then dynamic symbols and dynamic
relocs will not be displayed.

.IX Item \-s
.PD 0
.IP \fB\-\-symbols\fP 4
.IX Item \-\-symbols
.IP \fB\-\-syms\fP 4
.IX Item \-\-syms
.PD
Displays the entries in symbol table section of the file, if it has one.  If
a symbol has version information associated with it then this is displayed
as well.  The version string is displayed as a suffix to the symbol name,
preceded by an @ character.  For example \&\fBfoo@VER_1\fP.  If the version is
the default version to be used when resolving unversioned references to the
symbol then it is displayed as a suffix preceded by two @ characters.  For
example \&\fBfoo@@VER_2\fP.
.IP \fB\-\-dyn\-syms\fP 4
.IX Item \-\-dyn\-syms
Displays the entries in dynamic symbol table section of the file, if it has
one.  The output format is the same as the format used by the \&\fB\-\-syms\fP
option.
.IP \fB\-\-lto\-syms\fP 4
.IX Item \-\-lto\-syms
Displays the contents of any LTO symbol tables in the file.
.IP \fB\-\-sym\-base=[0|8|10|16]\fP 4
.IX Item \-\-sym\-base=[0|8|10|16]
Forces the size field of the symbol table to use the given base.  Any
unrecognized options will be treated as \fB0\fP.  \fB\-\-sym\-base=0\fP represents
the default and legacy behaviour.  This will output sizes as decimal for
numbers less than 100000.  For sizes 100000 and greater hexadecimal notation
will be used with a 0x prefix.  \&\fB\-\-sym\-base=8\fP will give the symbol sizes
in octal.  \&\fB\-\-sym\-base=10\fP will always give the symbol sizes in decimal.
\&\fB\-\-sym\-base=16\fP will always give the symbol sizes in hexadecimal with a
0x prefix.
.IP \fB\-C\fP 4
.IX Item \-C
.PD 0
.IP \fB\-\-demangle[=\fP\fIstyle\fP\fB]\fP 4
.IX Item \-\-demangle[=style]
.PD
Decode (\fIdemangle\fP) low\-level symbol names into user\-level names.  This
makes C++ function names readable.  Different compilers have different
mangling styles.  The optional demangling style argument can be used to
choose an appropriate demangling style for your compiler.
.IP \fB\-\-no\-demangle\fP 4
.IX Item \-\-no\-demangle
Do not demangle low\-level symbol names.  This is the default.
.IP \fB\-\-recurse\-limit\fP 4
.IX Item \-\-recurse\-limit
.PD 0
.IP \fB\-\-no\-recurse\-limit\fP 4
.IX Item \-\-no\-recurse\-limit
.IP \fB\-\-recursion\-limit\fP 4
.IX Item \-\-recursion\-limit
.IP \fB\-\-no\-recursion\-limit\fP 4
.IX Item \-\-no\-recursion\-limit
.PD
Enables or disables a limit on the amount of recursion performed whilst
demangling strings.  Since the name mangling formats allow for an infinite
level of recursion it is possible to create strings whose decoding will
exhaust the amount of stack space available on the host machine, triggering
a memory fault.  The limit tries to prevent this from happening by
restricting recursion to 2048 levels of nesting.
.Sp
The default is for this limit to be enabled, but disabling it may be
necessary in order to demangle truly complicated names.  Note however that
if the recursion limit is disabled then stack exhaustion is possible and any
bug reports about such an event will be rejected.
.IP "\fB\-U\fP \fI[d|i|l|e|x|h]\fP" 4
.IX Item "\-U [d|i|l|e|x|h]"
.PD 0
.IP \fB\-\-unicode=[default|invalid|locale|escape|hex|highlight]\fP 4
.IX Item \-\-unicode=[default|invalid|locale|escape|hex|highlight]
.PD
Controls the display of non\-ASCII characters in identifier names.  The
default (\fB\-\-unicode=locale\fP or \fB\-\-unicode=default\fP) is to treat them as
multibyte characters and display them in the current locale.  All other
versions of this option treat the bytes as UTF\-8 encoded values and attempt
to interpret them.  If they cannot be interpreted or if the
\fB\-\-unicode=invalid\fP option is used then they are displayed as a sequence of
hex bytes, encloses in curly parethesis characters.
.Sp
Using the \fB\-\-unicode=escape\fP option will display the characters as as
unicode escape sequences (\fI\euxxxx\fP).  Using the \&\fB\-\-unicode=hex\fP will
display the characters as hex byte sequences enclosed between angle
brackets.
.Sp
Using the \fB\-\-unicode=highlight\fP will display the characters as unicode
escape sequences but it will also highlighted them in red, assuming that
colouring is supported by the output device.  The colouring is intended to
draw attention to the presence of unicode sequences when they might not be
expected.
.IP \fB\-X\fP 4
.IX Item \-X
.PD 0
.IP \fB\-\-extra\-sym\-info\fP 4
.IX Item \-\-extra\-sym\-info
.PD
When displaying details of symbols, include extra information not normally
presented.  Currently this just adds the name of the section referenced by
the symbol's index field, if there is one.  In the future more information
may be displayed when this option is enabled.
.Sp
Enabling this option effectively enables the \fB\-\-wide\fP option as well, at
least when displaying symbol information.
.IP \fB\-\-no\-extra\-sym\-info\fP 4
.IX Item \-\-no\-extra\-sym\-info
Disables the effect of the \fB\-\-extra\-sym\-info\fP option.  This is the default.

unwind sections for IA64 ELF files, as well as ARM unwind tables
(\f(CW\*(C`.ARM.exidx\*(C'\fP / \f(CW\*(C`.ARM.extab\*(C'\fP) are currently
supported.  If support is not yet implemented for your architecture you
could try dumping the contents of the \fI.eh_frames\fP section using the
\&\fB\-\-debug\-dump=frames\fP or \fB\-\-debug\-dump=frames\-interp\fP options.

.PD
Quando si visualizzano i simboli, questa opzione fa sì che \fBreadelf\fP usi la
tabella simboli nella sezione dinamica del file, invece di quella nella

.IX Item \-\-dwarf\-depth=n
Limit the dump of the \f(CW\*(C`.debug_info\*(C'\fP section to \fIn\fP children.
This is only useful with \fB\-\-debug\-dump=info\fP.  The default is to print all
DIEs; the special value 0 for \fIn\fP will also have this effect.
.Sp
With a non\-zero value for \fIn\fP, DIEs at or deeper than \fIn\fP levels will not
be printed.  The range for \fIn\fP is zero\-based.
.IP \fB\-\-dwarf\-start=\fP\fIn\fP 4
.IX Item \-\-dwarf\-start=n
Print only DIEs beginning with the DIE numbered \fIn\fP.  This is only useful
with \fB\-\-debug\-dump=info\fP.
.Sp
If specified, this option will suppress printing of any header information
and all DIEs before the DIE numbered \fIn\fP.  Only siblings and children of
the specified DIE will be printed.
.Sp
This can be used in conjunction with \fB\-\-dwarf\-depth\fP.

Display the contents of non\-debug sections found in separate debuginfo files

\fB\-wK\fP option, and only sections requested by other command line options
will be displayed.
.IP \fB\-\-ctf[=\fP\fIsezione\fP\fB]\fP 4
.IX Item \-\-ctf[=sezione]
Display the contents of the specified CTF section.  CTF sections themselves
contain many subsections, all of which are displayed in order.
.Sp
By default, display the name of the section named \fI.ctf\fP, which is the name
emitted by \fBld\fP.
.IP \fB\-\-ctf\-parent=\fP\fImember\fP 4
.IX Item \-\-ctf\-parent=member
If the CTF section contains ambiguously\-defined types, it will consist of an
archive of many CTF dictionaries, all inheriting from one dictionary
containing unambiguous types.  This member is by default named \fI.ctf\fP, like
the section containing it, but it is possible to change this name using the
\f(CW\*(C`ctf_link_set_memb_name_changer\*(C'\fP function at link time.  When
looking at CTF archives that have been created by a linker that uses the
name changer to rename the parent archive member, \fB\-\-ctf\-parent\fP can be
used to specify the name used for the parent.

Don't break output lines to fit into 80 columns. By default \&\fBreadelf\fP
breaks section header and segment listing lines for 64\-bit ELF files, so
that they fit into 80 columns. This option causes \&\fBreadelf\fP to print each
section header resp. each segment one a single line, which is far more
readable on terminals wider than 80 columns.

Normally when readelf is displaying a symbol name, and it has to truncate
the name to fit into an 80 column display, it will add a suffix of
\f(CW\*(C`[...]\*(C'\fP to the name.  This command line option disables this
behaviour, allowing 5 more characters of the name to be displayed and
restoring the old behaviour of readelf (prior to release 2.35).

inserite al posto dell'opzione originale @\fIfile\fP. Se \fIfile\fP non esiste o
non può essere letto, l'opzione sarà trattata letteralmente, e non rimossa.

Le opzioni in \fIfile\fP sono separate da spazi vuoti. Si può includere uno
spazio vuoto in un'opzione racchiudendo l'intera opzione fra apici, singoli
o doppi. Può essere incluso qualsiasi carattere (compresa la barra inversa)
facendo precedere al carattere una barra inversa. Il \fIfile\fP può esso stesso
contenere ulteriori opzioni @\fIfile\fP; ciascuna di queste opzioni sarà
elaborata ricorsivamente.
