LLDB is the debugger project associated with Clang/LLVM. It + supports the Mac OS X, Linux, and &os; platforms, with Windows + support under development. It builds on existing components + in the larger LLVM project, for example using Clang's + expression parser and LLVM's disassembler.

+ +

Work over the last three months consisted mainly of + maintenance, ensuring that the upstream &os; port continues to + build and that testsuite failures are promptly addressed.

+ +

I plan to import a new LLDB snapshot after the base system + Clang is updated to 3.5. Some upstream improvements that will + be in that import include:

+ +

Ability to specify a count to thread step-* + operations.
Ongoing AArch64 development.
Significant progress on the lldb-gdbserver debug + stub.
I/O handling improvements.
A much faster C++ name demangler for most symbols.

+ +

A proof-of-concept implementation of kernel debugging support + for amd64 was completed as part of Google Summer of Code. It + is not ready to be committed, but will form the basis for + upcoming kernel debugging support.

+ + + DARP/AFRL + + SRI International + + University of Cambridge + + + +

Port remote debug stub (lldb-gdbserver) from Linux to + FreeBSD.

+ + + +

Add support for local and core file kernel debugging.

+ + + +

Implement, fix or test support on all non-amd64 + architectures.

+ + + +

Verify cross-debugging.

+ + + +

Investigate and fix test suite failures.

+ + + +

Package LLDB as a port.

+ + + +

Enable by default in the base system for working + architectures.
