LLVM的TableGen可以用来为td文件生成tags，方便在vim中查看。该功能的svn信息如下：

-———————————————————————– r177682 | silvas | 2013-03-22 07:40:38 +0800 (Fri, 22 Mar 2013) | 18 lines Changed paths: M /llvm/trunk/utils/TableGen/CMakeLists.txt A /llvm/trunk/utils/TableGen/CTagsEmitter.cpp M /llvm/trunk/utils/TableGen/TableGen.cpp M /llvm/trunk/utils/TableGen/TableGenBackends.h A /llvm/trunk/utils/TableGen/tdtags

Add TableGen ctags(1) emitter and helper script.

To use this in conjunction with exuberant ctags to generate a single combined tags file, run tblgen first and then $ ctags –append […]

Since some identifiers have corresponding definitions in C++ code, it can be useful (if using vim) to also use cscope, and :set cscopetagorder=1 so that :tag X will preferentially select the tablegen symbol, while :cscope find g X will always find the C++ symbol.

使用方法如下：

xmj@xmj-OptiPlex-9020:~/project/llvm-trunk$ bash utils/TableGen/tdtags -q -x all

生成的tags文件：

xmj@xmj-OptiPlex-9020:~/project/llvm-trunk$ find ./ -name tags ./unittests/Option/tags ./lib/IR/tags ./lib/LibDriver/tags ./lib/Target/AVR/tags ./lib/Target/XCore/tags ./lib/Target/WebAssembly/tags ./lib/Target/BPF/tags ./lib/Target/Sparc/tags ./lib/Target/Mips/tags ./lib/Target/NVPTX/tags ./lib/Target/SystemZ/tags ./lib/Target/PowerPC/tags ./lib/Target/Lanai/tags ./lib/Target/MSP430/tags ./lib/Target/X86/tags ./lib/Target/AArch64/tags ./lib/Target/Hexagon/tags ./lib/Target/ARM/tags ./lib/Target/AMDGPU/tags ./test/TableGen/tags ./include/llvm/IR/tags ./include/llvm/Option/tags ./include/llvm/Target/tags ./include/llvm/CodeGen/tags ./tools/clang/tags ./tools/clang/lib/StaticAnalyzer/Checkers/tags ./tools/clang/test/TableGen/tags ./tools/clang/include/clang/AST/tags ./tools/clang/include/clang/Driver/tags ./tools/clang/include/clang/Basic/tags ./tools/clang/include/clang/StaticAnalyzer/Checkers/tags
