NAME

6       xxx-tblgen - Target Description to C++ Code
7

SYNOPSIS

9       xxx-tblgen [options] [filename]
10

DESCRIPTION

12       xxx-tblgen  is  a family of programs that translates target description
13       (.td) files into C++ code and other output formats. Most users of  LLVM
14       will not need to use this program. It is used only for writing parts of
15       the compiler or LLVM target backends.
16
17       The details of the input and output of xxx-tblgen is beyond  the  scope
18       of this short introduction; please see the TableGen Overview for an in‐
19       troduction and for references to additional TableGen documents.
20
21       The filename argument specifies the  name  of  the  Target  Description
22       (.td) file that TableGen processes.
23

OPTIONS

25   General Options
26       -help  Print a description of the command line options.
27
28       -help-list
29              Print a description of the command line options in a simple list
30              format.
31
32       -D=macroname
33              Specify the name of a macro to be defined. The name is  defined,
34              but it has no particular value.
35
36       -d=filename
37              Specify the name of the dependency filename.
38
39       -debug Enable debug output.
40
41       -dump-json
42              Print a JSON representation of all records, suitable for further
43              automated processing.
44
45       -I directory
46              Specify where to find other target description files for  inclu‐

53
54       -o filename
55              Specify the output file name.  If filename is -, then xxx-tblgen
56              sends its output to standard output.

58       -print-records
59              Print all classes and records to standard output (default  back‐
60              end option).
