L LV M + A R M = ? Status of ARM platform support in LLVM and more Anton Korobeynikov [email protected] Outline 1. LLVM Compiler Infrastructure 2. Status: 1. Clang 2. Compiler-RT 3. Backend 3. Track, Use & Contribute 4. Interoperability Problems LLVM: What is it? Language independent optimizer and code generator - Many optimizations, many targets - Modern and library-based design LLVM: What is it? Language independent optimizer and code generator - Many optimizations, many targets - Modern and library-based design Clang C/C++/ObjectiveC frontend - Designed for speed, reusability, compatibility with GCC (not only!) extensions - Good also as indexing, analysis, refactoring tool LLVM: other subprojects 1. MC: operations on “machine code” - Assemblers, disassemblers, direct object code emission LLVM: other subprojects 1. MC: operations on “machine code” - Assemblers, disassemblers, direct object code emission 2. LLDB: low level debugger - Command line debugger - Reuses Clang parser, some JIT bits, MC disassemblers LLVM: other subprojects 1.
