DESCRIPTION

18       *-tblgen  is  a  family  of programs that translates target description
19       (.td) files into C++ code and other output formats. Most users of  LLVM
20       will not need to use this program. It is used only for writing parts of
21       the compiler, debugger, and LLVM target backends.
22
23       The details of the input and output of the *-tblgen programs is  beyond
24       the  scope of this short introduction; please see the TableGen Overview
25       for an introduction and for references  to  additional  TableGen  docu‐
26       ments.
27
28       The  filename  argument  specifies  the  name of the Target Description
29       (.td) file that TableGen processes.

OPTIONS

32   General Options
33       -help  Print a description of the command line options.
34
35       -help-list
36              Print a description of the command line options in a simple list
37              format.
38
39       -D=macroname
40              Specify  the name of a macro to be defined. The name is defined,
41              but it has no particular value.
42
43       -d=filename
44              Specify the name of the dependency filename.
45
46       -debug Enable debug output.
47
48       -dump-json
49              Print a JSON representation of all records, suitable for further
50              automated processing.
51
52       -I directory
53              Specify  where to find other target description files for inclu‐
54              sion.  The directory value should be a full or partial path to a

56
57       -null-backend
58              Parse the source files and build the records, but do not run any
59              backend. This is useful for timing the frontend.
60
61       -o filename
62              Specify the output file name.  If filename is -,  then  *-tblgen
63              sends its output to standard output.
64
65       -print-records
66              Print  all classes and records to standard output (default back‐
67              end option).
