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.

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.

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. .IP \fB\-P\fP 4 .IX Item \-P .PD 0 .IP \fB\-\-process\-links\fP 4 .IX Item \-\-process\-links .PD Display the contents of non\-debug sections found in separate debuginfo files that are linked to the main file. This option automatically implies the \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. .IP \fB\-\-ctf\-symbols=\fP\fIsezione\fP 4 .IX Item \-\-ctf\-symbols=sezione .PD 0 .IP \fB\-\-ctf\-strings=\fP\fIsezione\fP 4 .IX Item \-\-ctf\-strings=sezione .PD Specify the name of another section from which the CTF file can inherit strings and symbols. By default, the \f(CW\*(C`.symtab\*(C'\fP and its linked string table are used. .Sp If either of \fB\-\-ctf\-symbols\fP or \fB\-\-ctf\-strings\fP is specified, the other must be specified as well. .IP \fB\-I\fP 4 .IX Item \-I .PD 0 .IP \fB\-\-histogram\fP 4 .IX Item \-\-histogram .PD Visualizza un istogramma delle lunghezze dell'elenco del contenitore quando si visualizzano i contenuti delle tabelle simboli. .IP \fB\-v\fP 4 .IX Item \-v .PD 0 .IP \fB\-\-version\fP 4 .IX Item \-\-version .PD Visualizza il numero di versione di readelf. .IP \fB\-W\fP 4 .IX Item \-W .PD 0 .IP \fB\-\-wide\fP 4 .IX Item \-\-wide .PD 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. .IP \fB\-T\fP 4 .IX Item \-T .PD 0 .IP \fB\-\-silent\-truncation\fP 4 .IX Item \-\-silent\-truncation .PD 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). .IP \fB\-H\fP 4 .IX Item \-H .PD 0 .IP \fB\-\-help\fP 4 .IX Item \-\-help .PD Visualizza le opzioni della linea di comando capite da \fBreadelf\fP. .IP \fB@\fP\fIfile\fP 4 .IX Item @file Legge le opzioni da riga di comando da \fIfile\fP. Le opzioni lette sono 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. .Sp 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. .SH "VEDERE ANCHE" .IX Intestazione "VEDERE ANCHE" \&\fBobjdump\fP\|(1) e i campi Info per \fIbinutils\fP. .SH COPYRIGHT .IX Intestazione COPYRIGHT Copyright (c) 1991\-2024 Free Software Foundation, Inc. .PP È permesso copiare, distribuire e/o modificare questo documento nei termini della \*(lqLicenza per documentazione libera GNU\*(rq (GNU Free Documentation License), versione 1.3 o ogni versione successiva pubblicata dalla Free Software Foundation; senza sezioni non modificabili, senza testi di prima di copertina e di quarta di copertina.
