.SH SYNOPSIS
|
|
.sp
|
|
\fBllvm\-dwarfdump\fP [\fIoptions\fP] [\fIfilename ...\fP]
|
|
.SH DESCRIPTION
|
|
.sp
|
|
\fBllvm\-dwarfdump\fP parses DWARF sections in object files,
|
|
archives, and \fI\&.dSYM\fP bundles and prints their contents in
|
|
human\-readable form. Only the .debug_info section is printed unless one of
|
|
the section\-specific options or \fI\%\-\-all\fP is specified.
|
|
.sp
|
|
If no input file is specified, \fIa.out\fP is used instead. If \fI\-\fP is used as the
|
|
input file, \fBllvm\-dwarfdump\fP reads the input from its standard input
|
|
stream.
|
|
