URL: https://github.com/llvm/llvm-project/commit/fdc1638b5cbd7f93937dce56f8ea29db52390502 DIFF: https://github.com/llvm/llvm-project/commit/fdc1638b5cbd7f93937dce56f8ea29db52390502.diff LOG: [lldb] [Process/elf-core] Disable for FreeBSD vmcores Recognize FreeBSD vmcores (kernel core dumps) through OS ABI = 0xFF + ELF version = 0, and do not process them via the elf-core plugin. While these files use ELF as a container format, they contain raw memory dump rather than proper VM segments and therefore are not usable to the elf-core plugin.
