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 intro‐
18 duction; please see the introduction to TableGen.
19
20 The filename argument specifies the name of a Target Description (.td)
21 file to read as input.
22
24 -help Print a summary of command line options.
25
26 -o filename
27 Specify the output file name. If filename is -, then tblgen
28 sends its output to standard output.
29
30 -I directory
31 Specify where to find other target description files for inclu‐
32 sion. The directory value should be a full or partial path to a
33 directory that contains target description files.
34
35 -asmparsernum N
36 Make -gen-asm-parser emit assembly writer number N.
37
38 -asmwriternum N
39 Make -gen-asm-writer emit assembly writer number N.
40
41 -class className
42 Print the enumeration list for this class.
43
44 -print-records
45 Print all records to standard output (default).
46
47 -dump-json
48 Print a JSON representation of all records, suitable for further
49 automated processing.
50
51 -print-enums
52 Print enumeration values for a class.
53
54 -print-sets
55 Print expanded sets for testing DAG exprs.
56
57 -gen-emitter
58 Generate machine code emitter.
59
60 -gen-register-info
61 Generate registers and register classes info.
62
63 -gen-instr-info

74
75 -gen-dag-isel
76 Generate a DAG (Directed Acycle Graph) instruction selector.
77
78 -gen-asm-matcher
79 Generate assembly instruction matcher.
80
81 -gen-dfa-packetizer
82 Generate DFA Packetizer for VLIW targets.
83
84 -gen-fast-isel
85 Generate a "fast" instruction selector.
86
87 -gen-subtarget
88 Generate subtarget enumerations.
89
90 -gen-intrinsic-enums
91 Generate intrinsic enums.
92
93 -gen-intrinsic-impl
94 Generate intrinsic implementation.
95
96 -gen-tgt-intrinsic
97 Generate target intrinsic information.
98
99 -gen-enhanced-disassembly-info
100 Generate enhanced disassembly info.
101
102 -version
103 Show the version number of this program.
104
106 If tblgen succeeds, it will exit with 0. Otherwise, if an error
107 occurs, it will exit with a non-zero value.
