| macOS |
| ----- |
| |
| LLDB has matured a lot in the last year and can be used for C, C++ and |
| Objective-C development for x86_64, i386 and ARM debugging. The entire public |
| API is exposed though a framework on Mac OS X which is used by Xcode, the lldb |
| command line tool, and can also be used by Python. The entire public API is |
| exposed through script bridging which allows LLDB to use an embedded Python |
| script interpreter, as well as having a Python module named "lldb" which can be |
| used from Python on the command line. This allows debug sessions to be |
| scripted. It also allows powerful debugging actions to be created and attached |
| to a variety of debugging workflows. |
| |
| Linux |
| ----- |
| |
| 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. |
| |
| FreeBSD |
| ------- |
| |
| LLDB on FreeBSD lags behind the Linux implementation but is improving rapidly. |
| For more details, see the Features by OS section below. |
| |
| Windows |
| ------- |
| |
| LLDB on Windows is still under development, but already useful for i386 |
| programs (x86_64 untested) built with DWARF debug information, including |
| postmortem analysis of minidumps. For more details, see the Features by OS |
| section below. |
