Author: emaste Date: Wed Dec 16 19:23:10 2015 New Revision: 292350 URL: https://svnweb.freebsd.org/changeset/base/292350 Log: Enable LLDB by default on amd64 and arm64 LLDB is usable for userland core file and live debugging on amd64, and for userland core file debugging on arm64. In general it works at least as well on FreeBSD as our in-tree gdb version, so enable it by default to allow for broader use and testing. An LLDB tutorial is available at http://lldb.llvm.org/tutorial.html, and a table mapping GDB commands to LLDB commands can be found at http://lldb.llvm.org/lldb-gdb.html . LLDB also has some level of support for FreeBSD on arm, mips, i386, and powerpc, but is not yet ready to have them enabled by default.
