tblgen - Description to C++ Code

clang-tblgen [options] [filename]

lldb-tblgen [options] [filename]

llvm-tblgen [options] [filename]

mlir-tblgen [options] [filename]

*-tblgen is a family of programs that translates target description (.td) files into C++ code and other output formats. Most users of LLVM will not need to use this program. It is used only for writing parts of the compiler, debugger, and LLVM target backends.

The details of the input and output of the *-tblgen programs is beyond the scope of this short introduction; please see the TableGen Overview for an introduction and for references to additional TableGen documents.

The filename argument specifies the name of the Target Description (.td) file that TableGen processes.

Print a description of the command line options.

-help-list
Print a description of the command line options in a simple list format.

Specify the name of a macro to be defined. The name is defined, but it has no particular value.

Specify the name of the dependency filename.

Enable debug output.

Print a JSON representation of all records, suitable for further automated processing.

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.

Parse the source files and build the records, but do not run any backend. This is useful for timing the frontend.

Specify the output file name. If filename is -, then *-tblgen sends its output to standard output.

Print all classes and records to standard output (default backend option).

Print a detailed report of all global variables, classes, and records to standard output.

Print a report with any statistics collected by the backend.

Time the parser and backend phases and print a report.

Show the version number of the program.

Write the output file only if it is new or has changed.
