 llvm-extract - extract a function from an LLVM module
 =====================================================
 
-
 SYNOPSIS
 --------
 
-
-**llvm-extract** [*options*] **--func** *function-name* [*filename*]
-
+:program:`llvm-extract` [*options*] **--func** *function-name* [*filename*]
 
 DESCRIPTION
 -----------
 
-
-The **llvm-extract** command takes the name of a function and extracts it from
-the specified LLVM bitcode file.  It is primarily used as a debugging tool to
-reduce test cases from larger programs that are triggering a bug.
+The :program:`llvm-extract` command takes the name of a function and extracts
+it from the specified LLVM bitcode file.  It is primarily used as a debugging
+tool to reduce test cases from larger programs that are triggering a bug.
 
 In addition to extracting the bitcode of the specified function,
-**llvm-extract** will also remove unreachable global variables, prototypes, and
-unused types.
-
-The **llvm-extract** command reads its input from standard input if filename is
-omitted or if filename is -.  The output is always written to standard output,
-unless the **-o** option is specified (see below).
+:program:`llvm-extract` will also remove unreachable global variables,

+The :program:`llvm-extract` command reads its input from standard input if

 OPTIONS
 -------
 
-
-
 **-f**
 
- Enable binary output on terminals.  Normally, **llvm-extract** will refuse to
- write raw bitcode output if the output stream is a terminal. With this option,
- **llvm-extract** will write raw bitcode regardless of the output device.

 llvm-nm - list LLVM bitcode and object file's symbol table
 ==========================================================
 
-
 SYNOPSIS
 --------
 
-
 :program:`llvm-nm` [*options*] [*filenames...*]
 
-
 DESCRIPTION
 -----------
 
-
 The :program:`llvm-nm` utility lists the names of symbols from the LLVM bitcode
 files, object files, or :program:`ar` archives containing them, named on the
-command line. Each symbol is listed along with some simple information about its
-provenance. If no file name is specified, or *-* is used as a file name,
+command line.  Each symbol is listed along with some simple information about
+its provenance.  If no file name is specified, or *-* is used as a file name,
 :program:`llvm-nm` will process a file on its standard input stream.
 
 :program:`llvm-nm`'s default output format is the traditional BSD :program:`nm`
-output format. Each such output record consists of an (optional) 8-digit
+output format.  Each such output record consists of an (optional) 8-digit
 hexadecimal address, followed by a type code character, followed by a name, for
-each symbol. One record is printed per line; fields are separated by spaces.
+each symbol.  One record is printed per line; fields are separated by spaces.
 When the address is omitted, it is replaced by 8 spaces.
 
 Type code characters currently supported, and their meanings, are as follows:
 
-
 U
 
  Named object is referenced but undefined in this bitcode file
 
-
-
 C
 
  Common (multiple definitions link together into one def)
 
-
-
 W
 
  Weak reference (multiple definitions link together into zero or one definitions)
 
-
-
 t
 
  Local function (text) object
 
-
-
 T
 
  Global function (text) object
 
-
-
 d
 
  Local data object
 
-
-
 D
 
  Global data object
 
-
-
 ?
 
  Something unrecognizable
 
-
-
 Because LLVM bitcode files typically contain objects that are not considered to
 have addresses until they are linked into an executable image or dynamically
 compiled "just-in-time", :program:`llvm-nm` does not print an address for any
 symbol in an LLVM bitcode file, even symbols which are defined in the bitcode
 file.

 BUGS
 ----
 
-
  * :program:`llvm-nm` cannot demangle C++ mangled names, like GNU :program:`nm`
    can.
 
  * :program:`llvm-nm` does not support the full set of arguments that GNU
    :program:`nm` does.
 
-
 EXIT STATUS
 -----------
 
-
 :program:`llvm-nm` exits with an exit code of zero.
