@ -3214,26 +3214,33 @@ standard input, and prints the file name and line number for each
address on standard output. In this mode, @command{addr2line} may be used
in a pipe to convert dynamically chosen addresses.
The format of the output is @samp{FILENAME:LINENO}. The file name and
line number for each input address is printed on separate lines.
The format of the output is @samp{FILENAME:LINENO}. By default
each input address generates one line of output.
If the @option{-f} option is used, then each @samp{FILENAME:LINENO}
line is preceded by @samp{FUNCTIONNAME} which is the name of the
function containing the address.
Two options can generate additional lines before each
@samp{FILENAME:LINENO} line (in that order).
If the @option{-a} option is used then a line with the input address
is displayed.
If the @option{-f} option is used, then a line with the
@samp{FUNCTIONNAME} is displayed. This is the name of the function
containing the address.
One option can generate additional lines after the
@samp{FILENAME:LINENO} line.
If the @option{-i} option is used and the code at the given address is
present there because of inlining by the compiler then the
@samp{@{FUNCTIONNAME@} FILENAME:LINENO} information for the inlining
function will be displayed afterwards. This continues recursively
until there is no more inlining to report.
present there because of inlining by the compiler then additional
lines are displayed afterwards. One or two extra lines (if the
@option{-f} option is used) are displayed for each inlined function.
If the @option{-a} option is used then the output is prefixed by the
input address.
If the @option{-p} option is used then the output for each input
address is displayed on one, possibly quite long, line. If
@option{-p} is not used then the output is broken up into multiple
lines, based on the paragraphs above.
Alternatively if the @option{-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
@option{-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 @samp{(inlined by)}.
If the file name or function name can not be determined,
@command{addr2line} will print two question marks in their place. If the
