| |
| FreeBSD |
| ------- |
| |
| LLDB on FreeBSD lags behind the Linux implementation but is improving rapidly. |
| For more details, see the Features by OS section below. |
| |
| Linux |
| ----- |
| |
| LLDB is improving on Linux. Linux is nearing feature completeness with Darwin |
| to debug x86_64, i386, ARM, AArch64, IBM POWER (ppc64), IBM Z (s390x), and |
| MIPS64 programs. For more details, see the Features by OS section below. |
| |
| macOS |
| ----- |
| |
| LLDB is the system debugger on macOS, iOS, tvOS, and watchOS and |
| can be used for C, C++, Objective-C and Swift development for x86_64, |
| i386, ARM, and AArch64 debugging. The entire public API is exposed |
| through a macOS framework which is used by Xcode and the `lldb` |
| command line tool. It can also be imported from 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. |
| |
| NetBSD |
| ------ |
| |
| LLDB is improving on NetBSD and reaching feature completeness with Linux. |
| |
| 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. |
