LLVM TableGen Language Support

VSCode extension for LLVM TableGen (.td) files with syntax highlighting and language server features.

Features

• Syntax highlighting
• Go to Definition (classes, defs, multiclasses, fields, template arguments)
• Rename symbols
• Document outline
• Type-aware field resolution (obj.field, ClassName<args>.field)
• let binding resolution (jumps to original field definition in parent class)

Configuration

Setting	Description	Default
tablegen.compileCommandsPath	Path to tablegen_compile_commands.yml	${workspaceFolder}/tablegen_compile_commands.yml

Supports environment variables: ${env:VAR_NAME}

How It Works

Uses tablegen_compile_commands.yml (generated by LLVM's CMake build) to build an include graph. Files are lazily indexed when opened. Symbol resolution respects scoping and inheritance.
