LLDB is improving on Linux. While the debugserver has not been ported (to enable remote debugging) Linux is nearing feature completeness with Darwin to debug x86_64 programs, and is partially working with i386 programs. ARM architectures on Linux are untested. For more details, see the Features by OS section below.
