6 tblgen - Target Description To C++ Code Generator
7
9 tblgen [options] [filename]
10
12 tblgen translates from target description (.td) files into C++ code
13 that can be included in the definition of an LLVM target library. Most
14 users of LLVM will not need to use this program. It is only for
15 assisting with writing an LLVM target backend.
16
17 The input and output of tblgen is beyond the scope of this short
18 introduction. Please see the CodeGeneration page in the LLVM
19 documentation.
20
21 The filename argument specifies the name of a Target Description (.td)
22 file to read as input.
23
25 -help
26 Print a summary of command line options.
27
28 -o filename
29 Specify the output file name. If filename is "-", then tblgen
30 sends its output to standard output.
31
32 -I directory
33 Specify where to find other target description files for inclusion.
34 The directory value should be a full or partial path to a directory
35 that contains target description files.
36
37 -asmwriternum N
38 Make -gen-asm-writer emit assembly writer number N.
39
40 -class class Name
41 Print the enumeration list for this class.
42
43 -print-records
44 Print all records to standard output (default).
45
46 -print-enums
47 Print enumeration values for a class
48
49 -gen-emitter
50 Generate machine code emitter.
51
52 -gen-register-enums
53 Generate the enumeration values for all registers.
54
55 -gen-register-desc
56 Generate a register info description for each register.
57
58 -gen-register-desc-header
59 Generate a register info description header for each register.
60
61 -gen-instr-enums
62 Generate enumeration values for instructions.
63
64 -gen-instr-desc
65 Generate instruction descriptions.
66
67 -gen-asm-writer
68 Generate the assembly writer.
69
70 -gen-dag-isel
71 Generate a DAG (Directed Acycle Graph) instruction selector.
72
73 -gen-subtarget
74 Generate subtarget enumerations.
75
76 -gen-intrinsic
77 Generate intrinsic information.
78
79 -version
80 Show the version number of this program.
81
83 If tblgen succeeds, it will exit with 0. Otherwise, if an error
84 occurs, it will exit with a non-zero value.
