The default is the file \fIa.out\fR. The section in the relocatable +object to use is specified with the \fB\-j\fR option. +.PP +\&\fBaddr2line\fR has two modes of operation. +.PP +In the first, hexadecimal addresses or symbol+offset are specified on the command line, +and \fBaddr2line\fR displays the file name and line number for each +address. +.PP +In the second, \fBaddr2line\fR reads hexadecimal addresses or symbol+offset from +standard input, and prints the file name and line number for each +address on standard output. In this mode, \fBaddr2line\fR may be used +in a pipe to convert dynamically chosen addresses. +.PP +The format of the output is \fBFILENAME:LINENO\fR. By default +each input address generates one line of output. +.PP +Two options can generate additional lines before each +\&\fBFILENAME:LINENO\fR line (in that order). +.PP +If the \fB\-a\fR option is used then a line with the input address +is displayed. +.PP +If the \fB\-f\fR option is used, then a line with the +\&\fBFUNCTIONNAME\fR is displayed. This is the name of the function +containing the address. +.PP +One option can generate additional lines after the +\&\fBFILENAME:LINENO\fR line. +.PP +If the \fB\-i\fR 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 +\&\fB\-f\fR option is used) are displayed for each inlined function. +.PP +Alternatively if the \fB\-p\fR 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 +\&\fB\-i\fR 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 \fB(inlined by)\fR. +.PP +If the file name or function name can not be determined, +\&\fBaddr2line\fR will print two question marks in their place. If the +line number can not be determined, \fBaddr2line\fR will print 0. +.PP +When symbol+offset is used, +offset is optional, except when the symbol +is ambigious with a hex number. The resolved symbols can be mangled +or unmangled, except unmangled symbols with + are not allowed. +.SH OPTIONS +.IX Header "OPTIONS" +The long and short forms of options, shown here as alternatives, are +equivalent. +.IP \fB\-a\fR 4 +.IX Item "-a" +.PD 0 +.IP \fB\-\-addresses\fR 4 +.IX Item "--addresses" +.PD +Display the address before the function name, file and line number +information. The address is printed with a \fB0x\fR prefix to easily +identify it. +.IP "\fB\-b\fR \fIbfdname\fR" 4 +.IX Item "-b bfdname" +.PD 0 +.IP \fB\-\-target=\fR\fIbfdname\fR 4 +.IX Item "--target=bfdname" +.PD +Specify that the object-code format for the object files is +\&\fIbfdname\fR. +.IP \fB\-C\fR 4 +.IX Item "-C" +.PD 0 +.IP \fB\-\-demangle[=\fR\fIstyle\fR\fB]\fR 4 +.IX Item "--demangle[=style]" +.PD +Decode (\fIdemangle\fR) 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. +.IP "\fB\-e\fR \fIfilename\fR" 4 +.IX Item "-e filename" +.PD 0 +.IP \fB\-\-exe=\fR\fIfilename\fR 4 +.IX Item "--exe=filename" +.PD +Specify the name of the executable for which addresses should be +translated. The default file is \fIa.out\fR. +.IP \fB\-f\fR 4 +.IX Item "-f" +.PD 0 +.IP \fB\-\-functions\fR 4 +.IX Item "--functions" +.PD +Display function names as well as file and line number information. +.IP \fB\-s\fR 4 +.IX Item "-s" +.PD 0 +.IP \fB\-\-basenames\fR 4 +.IX Item "--basenames" +.PD +Display only the base of each file name. +.IP \fB\-i\fR 4 +.IX Item "-i" +.PD 0 +.IP \fB\-\-inlines\fR 4 +.IX Item "--inlines" +.PD +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 \f(CW\*(C`main\*(C'\fR inlines +\&\f(CW\*(C`callee1\*(C'\fR which inlines \f(CW\*(C`callee2\*(C'\fR, and address is from +\&\f(CW\*(C`callee2\*(C'\fR, the source information for \f(CW\*(C`callee1\*(C'\fR and \f(CW\*(C`main\*(C'\fR +will also be printed. +.IP \fB\-j\fR 4 +.IX Item "-j" +.PD 0 +.IP \fB\-\-section\fR 4 +.IX Item "--section" +.PD +Read offsets relative to the specified section instead of absolute addresses. +.IP \fB\-p\fR 4 +.IX Item "-p" +.PD 0 +.IP \fB\-\-pretty\-print\fR 4 +.IX Item "--pretty-print" +.PD +Make the output more human friendly: each location are printed on one line. +If option \fB\-i\fR is specified, lines for all enclosing scopes are +prefixed with \fB(inlined by)\fR. +.IP \fB\-r\fR 4 +.IX Item "-r" +.PD 0 +.IP \fB\-R\fR 4 +.IX Item "-R" +.IP \fB\-\-recurse\-limit\fR 4 +.IX Item "--recurse-limit" +.IP \fB\-\-no\-recurse\-limit\fR 4 +.IX Item "--no-recurse-limit" +.IP \fB\-\-recursion\-limit\fR 4 +.IX Item "--recursion-limit" +.IP \fB\-\-no\-recursion\-limit\fR 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. +.Sp +The \fB\-r\fR option is a synonym for the +\&\fB\-\-no\-recurse\-limit\fR option. The \fB\-R\fR option is a +synonym for the \fB\-\-recurse\-limit\fR option. +.Sp +Note this option is only effective if the \fB\-C\fR or +\&\fB\-\-demangle\fR option has been enabled. +.IP \fB@\fR\fIfile\fR 4 +.IX Item "@file" +Read command-line options from \fIfile\fR. The options read are +inserted in place of the original @\fIfile\fR option. If \fIfile\fR +does not exist, or cannot be read, then the option will be treated +literally, and not removed. +.Sp +Options in \fIfile\fR 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 \fIfile\fR may itself contain additional +@\fIfile\fR options; any such options will be processed recursively. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +Info entries for \fIbinutils\fR. +.SH COPYRIGHT +.IX Header "COPYRIGHT" +Copyright (c) 1991\-2024 Free Software Foundation, Inc. +.PP +Permission is granted to copy, distribute and/or modify this document +under the terms of the GNU Free Documentation License, Version 1.3 +or any later version published by the Free Software Foundation; +with no Invariant Sections, with no Front-Cover Texts, and with no +Back-Cover Texts.
