KUVAUS
addr2line translates addresses into file names and line numbers. Given an address in an executable or an
offset in a section of a relocatable object, it uses the debugging information to figure out which file
name and line number are associated with it.
The executable or relocatable object to use is specified with the -e option. The default is the file
a.out. The section in the relocatable object to use is specified with the -j option.
addr2line käsittää kaksi toimintamoodia.
Ensimmäisessä, heksadesimaali-osoitteet määritellään komentorivillä, ja addr2line näyttää tiedostonimen
ja rivinumeron jokaiselle osoitteelle.
Toisessa, addr2line lukee heksadesimaali-osoitteet vakiosyötteestä, ja tulostaa tiedostonimen ja
rivinumeron jokaiselle vakiosyötteen osoitteelle. Tässä moodissa addr2line:a voidaan käyttää putkessa
muuntamaan dynaamisesti valittuja osoitteita.
The format of the output is FILENAME:LINENO. By default each input address generates one line of output.
Two options can generate additional lines before each FILENAME:LINENO line (in that order).
If the -a option is used then a line with the input address is displayed.
If the -f option is used, then a line with the FUNCTIONNAME is displayed. This is the name of the
function containing the address.
One option can generate additional lines after the FILENAME:LINENO line.
If the -i option is used and the code at the given address is present there because of inlining by the
compiler then additional lines are displayed afterwards. One or two extra lines (if the -f option is
used) are displayed for each inlined function.
Alternatively if the -p option is used then each input address generates a single, long, output line
containing the address, the function name, the file name and the line number. If the -i option has also
been used then any inlined functions will be displayed in the same manner, but on separate lines, and
prefixed by the text (inlined by).
Jos tiedostonimeä tai kutsun nimeä ei voida selvittää, addr2line tulostaa kaksi kysymysmerkkiä niiden
paikalla. Jos rivinumeroa ei voida selvittää, addr2line tulostaa 0.
VALITSIMET
Tässä on esitetty sekä lyhyet että pitkät muodot komentorivioptioista. Ne ovat toiminnoiltaan
identtisiä.
-a
--addresses
Display the address before the function name, file and line number information. The address is
printed with a 0x prefix to easily identify it.
-b bfdnimi
--target=bfdnimi
Specify that the object-code format for the object files is bfdname.
-C
--demangle[=style]
Decode (demangle) low-level symbol names into user-level names. Besides removing any initial
underscore prepended by the system, 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.
-e tiedostonimi
--exe=tiedostonimi
Määrittää ajettavan tiedoston nimen mistä osoitteet pitäisi tulkita. Oletus tiedosto on a.out.
-f
--functions
Näyttää kutsunumet kuten myös tiedosto- ja rivinumerotiedot.
-s
--basenames
Näyttää vain jokaisen tiedostonimen kannat.
-i
--inlines
If the address belongs to a function that was inlined, the source information for all enclosing
scopes back to the first non-inlined function will also be printed. For example, if "main" inlines
"callee1" which inlines "callee2", and address is from "callee2", the source information for
"callee1" and "main" will also be printed.
-j
--section
Read offsets relative to the specified section instead of absolute addresses.
-p
--pretty-print
Make the output more human friendly: each location are printed on one line. If option -i is
specified, lines for all enclosing scopes are prefixed with (inlined by).
-r
-R
--recurse-limit
--no-recurse-limit
--recursion-limit
--no-recursion-limit
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.
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.
The -r option is a synonym for the --no-recurse-limit option. The -R option is a synonym for the
--recurse-limit option.
Note this option is only effective if the -C or --demangle option has been enabled.
@tiedosto
Read command-line options from file. The options read are inserted in place of the original @file
option. If file does not exist, or cannot be read, then the option will be treated literally, and
not removed.
Options in file are separated by whitespace. A whitespace character may be included in an option by
surrounding the entire option in either single or double quotes. Any character (including a
backslash) may be included by prefixing the character to be included with a backslash. The file may
itself contain additional @file options; any such options will be processed recursively.
