+tblgen - Target Description To C++ Code Generator
+=================================================
+
+
+SYNOPSIS
+--------
+
+
+**tblgen** [*options*] [*filename*]
+
+
+DESCRIPTION
+-----------
+
+
+**tblgen** translates from target description (.td) files into C++ code that can
+be included in the definition of an LLVM target library. Most users of LLVM will
+not need to use this program. It is only for assisting with writing an LLVM
+target backend.
+
+The input and output of **tblgen** is beyond the scope of this short
+introduction. Please see the *CodeGeneration* page in the LLVM documentation.
+
+The *filename* argument specifies the name of a Target Description (.td) file
+to read as input.
+
+
+OPTIONS
+-------
+
+
+
+**-help**
+
+ Print a summary of command line options.
+
+
+
+**-o** *filename*
+
+ Specify the output file name.  If *filename* is ``-``, then **tblgen**
+ sends its output to standard output.
+
+
+
+**-I** *directory*
+
+ Specify where to find other target description files for inclusion. The
+ *directory* value should be a full or partial path to a directory that contains
+ target description files.
+
+
+
+**-asmparsernum** *N*
+
+ Make -gen-asm-parser emit assembly writer number *N*.
+
+
+
+**-asmwriternum** *N*
+
+ Make -gen-asm-writer emit assembly writer number *N*.
+
+
+
+**-class** *class Name*
+
+ Print the enumeration list for this class.
+
+
+
+**-print-records**
+
+ Print all records to standard output (default).
+
+
+
+**-print-enums**
+
+ Print enumeration values for a class
+
+
+
+**-print-sets**
+
+ Print expanded sets for testing DAG exprs.
+
+
+
+**-gen-emitter**
+
+ Generate machine code emitter.
+
+
+
+**-gen-register-info**
+
+ Generate registers and register classes info.

+**-gen-dag-isel**
+
+ Generate a DAG (Directed Acycle Graph) instruction selector.
+
+
+
+**-gen-asm-matcher**
+
+ Generate assembly instruction matcher.

+
+
+**-gen-dfa-packetizer**
+
+ Generate DFA Packetizer for VLIW targets.
+
+
+
+**-gen-fast-isel**
+
+ Generate a "fast" instruction selector.
+
+
+
+**-gen-subtarget**
+
+ Generate subtarget enumerations.
+
+
+
+**-gen-intrinsic**
+
+ Generate intrinsic information.
+

+
+EXIT STATUS
+-----------
+
+
+If **tblgen** succeeds, it will exit with 0.  Otherwise, if an error
+occurs, it will exit with a non-zero value.
