| =head1 NAME | |
| tblgen - Target Description To C++ Code Generator | |
| =head1 SYNOPSIS | |
| B<tblgen> [I<options>] [I<filename>] | |
| =head1 DESCRIPTION | |
| B<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 B<tblgen> is beyond the scope of this short | |
| introduction. Please see the I<CodeGeneration> page in the LLVM documentation. | |
| The F<filename> argument specifies the name of a Target Description (.td) file | |
| to read as input. | |
| =head1 OPTIONS | |
| =over | |
| =item B<-help> | |
| Print a summary of command line options. | |
| =item B<-o> F<filename> | |
| Specify the output file name. If F<filename> is C<->, then B<tblgen> | |
| sends its output to standard output. | |
| =item B<-I> F<directory> | |
| Specify where to find other target description files for inclusion. The | |
| F<directory> value should be a full or partial path to a directory that contains | |
| target description files. | |
| =item B<-asmwriternum> F<N> | |
| Make -gen-asm-writer emit assembly writer number F<N>. | |
| =item B<-class> F<class Name> | |
| Print the enumeration list for this class. | |
| =item B<-print-records> | |
| Print all records to standard output (default). | |
| =item B<-print-enums> | |
| Print enumeration values for a class | |
| =item B<-gen-emitter> | |
| Generate machine code emitter. | |
| =item B<-gen-register-enums> | |
| Generate the enumeration values for all registers. | |
| =item B<-gen-register-desc> | |
| Generate a register info description for each register. | |
| =item B<-gen-register-desc-header> | |
| Generate a register info description header for each register. | |
| =item B<-gen-instr-enums> | |
| Generate enumeration values for instructions. | |
| =item B<-gen-instr-desc> | |
| Generate instruction descriptions. | |
| =item B<-gen-asm-writer> | |
| Generate the assembly writer. | |
| =item B<-gen-dag-isel> | |
| Generate a DAG (Directed Acycle Graph) instruction selector. | |
| =item B<-gen-subtarget> | |
| Generate subtarget enumerations. | |
| =item B<-gen-intrinsic> | |
| Generate intrinsic information. | |
| =item B<-version> | |
| Show the version number of this program. | |
| =back | |
| =head1 EXIT STATUS | |
| If B<tblgen> succeeds, it will exit with 0. Otherwise, if an error | |
| occurs, it will exit with a non-zero value. | |
