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
|
||
|
|
