+
+LLDB (Terminal) User Interface
+------------------------------
+
+This directory contains the curses user interface for LLDB. To use it, ensure Python can find your lldb module. You may have to modify PYTHONPATH for that purpose:
+
+$ export PYTHONPATH=/path/to/lldb/module
+
+Then, run the lui.py. To load a core file:
+$ ./lui.py --core core
+
+To create a target from an executable:
+$ ./lui.py /bin/echo "hello world"
+
+To attach to a running process:
+$ ./lui.py --attach <pid>
+
+
+Known Issues
+------------
+1. Resizing the terminal will most likely cause lui to crash.
+2. Missing paging in command-window
+3. Only minimal testing (on Ubuntu Linux x86_64)
+
+Missing Features
+----------------
+- stdin/stdout/stderr windows
+- memory window
+- backtrace window
+- threads window
+- tab-completion
+- syntax-highlighting (via pygments library)
+- (local) variables window
+- registers window
+- disassembly window
+- custom layout

+syncsource.py
+
+OVERVIEW
+
+The syncsource.py utility transfers groups of files between
+computers. The primary use case is to enable developing LLVM project
+software on one machine, transfer it efficiently to other machines ---
+possibly of other architectures --- and test it there. syncsource.py
+supports configurable, named source-to-destination mappings and has a
+transfer agent plug-in architecture. The current distribution provides
+an rsync-over-ssh transfer agent.
+
+The primary benefits of using syncsource.py are:
+
+* Provides a simple, reliable way to get a mirror copy of primary-
+ machine files onto several different destinations without concern
+ of compromising the patch during testing on different machines.
+
+* Handles directory-mapping differences between two machines. For
+ LLDB, this is helpful when going between OS X and any other non-OS X
+ target system.
+
+EXAMPLE WORKFLOW
+
+This utility was developed in the context of working on the LLDB
+project. Below we show the transfers we'd like to have happen,
+and the configuration that supports it.
+
+Workflow Example:
+
+* Develop on OS X (primary machine)
+* Test candidate changes on OS X.
+* Test candidate changes on a Linux machine (machine-name: lldb-linux).
+* Test candidate changes on a FreeBSD machine (machine-name: lldb-freebsd).
+* Do check-ins from OS X machine.
+
+Requirements:
+
+* OS X machine requires the lldb source layout: lldb, lldb/llvm,
+ lldb/llvm/tools/clang. Note this is different than the canonical
+ llvm, llvm/tools/clang, llvm/tools/lldb layout that we'll want on
+ the Linux and FreeBSD test machines.
+
+* Linux machine requires the llvm, llvm/tools/clang and
+ llvm/tools/lldb layout.
+
+* FreeBSD machine requires the same layout as the llvm machine.
+
+syncsource.py configuration in ~/.syncsourcerc:
+
+# This is my configuration with a comment. Configuration
+# files are JSON-based.
+{ "configurations": [
+ # Here we have a collection of named configuration blocks.
+ # Configuration blocks can chain back to a parent by name.
+ {
+ # Every block has a name so it can be referenced from
+ # the command line or chained back to by a child block
+ # for sharing.
+ "name": "base_tot_settings",

+ "base_dir": "~/work/lldb-tot",
+ "llvm_dir": "lldb/llvm",
+ "clang_dir": "lldb/llvm/tools/clang"
+ },
+
+ # source_excludes covers any exclusions that:
+ # * should be applied when copying files from the source
+ # * should be excluded from deletion on the destination
+ #
+ # By default, ".git", ".svn" and ".pyc" are added to
+ # all dir-id exclusions. The default excludes can be
+ # controlled by the syncsource.py --default-excludes
+ # option.
+ #
+ # Below, I have transfer of the lldb dir skip everything
+ # rooted at "/llvm" below the lldb dir. This is
+ # because we want the source OS X lldb to move to
+ # a destination of {some-dest-root}/llvm/tools/lldb, and
+ # not have the OS-X-inverted llvm copy over with the lldb
+ # transfer portion. We'll see the complete picture of
+ # how this works when we get to specifying destinations
+ # later on in the config.
+ #
+ # We also exclude the "/build" and "/llvm-build" dir rooted in
+ # the OS X-side sources. The Xcode configuration on this
+ # OS X machine will dump lldb builds in the /build directory
+ # relative to the lldb dir, and it will build llvm+clang in
+ # the /llvm-build dir relative to the lldb dir.
+ #
+ # Note the first forward slash in "/build" indicates to the
+ # transfer agent that we only want to exclude the
+ # ~/work/lldb-tot/lldb/build dir, not just any file or
+ # directory named "build" somewhere underneath the lldb
+ # directory. Without the leading forward slash, any file
+ # or directory called build anywhere underneath the lldb dir
+ # will be excluded, which is definitely not what we want here.
+ #
+ # For the llvm dir, we do a source-side exclude for
+ # "/tools/clang". We manage the clang transfer as a separate
+ # entity, so we don't want the movement of llvm to also move
+ # clang.
+ #
+ # The llvm_dir exclusion of "/tools/lldb" is the first example
+ # of an exclude targeting a requirement of the destination
+ # side. Normally the transfer agent will delete anything on
+ # the destination that is not present on the source. It is
+ # trying to mirror, and ensure both sides have the same
+ # content. The source side of llvm on OS X does not have a
+ # "/tools/lldb", so at first this exclude looks non-sensical.
+ # But on the canonical destination layout, lldb lives in
+ # {some-dest-root}/llvm/tools/lldb. Without this exclude,
+ # the transfer agent would blow away the tools/lldb directory
+ # on the destination every time we transfer, and then have to
+ # copy the lldb dir all over again. For rsync+ssh, that
+ # totally would defeat the huge transfer efficiencies gained
+ # by using rsync in the first place.
+ #
+ # Note the overloading of both source and dest style excludes
+ # ultimately comes from the rsync-style exclude mechanism.
+ # If it wasn't for that, I would have separated source and
+ # dest excludes out better.

+ #
+ # As before, each dir-id used in this configuration is

+ #
+ # Note we see the untangling of the OS X lldb-centric
+ # directory structure to the canonical llvm,

+ # We are mapping lldb into a subdirectory of the llvm

+ "parent": "lldb-linux"
+ }
+]
+}
+
+Using it
+
+Now that we have a .syncsourcerc file set up, we can do a transfer.
+The .syncsourcerc file will be searched for as follows, using the
+first one that is found:
+
+* First check the --rc-file RCFILE option. If this is specified
+ and doesn't exist, it will raise an error and quit.
+
+* Check if the current directory has a .syncsourcerc file. If so,
+ use that.
+
+* Use the .syncsourcerc file from the user's home directory.
+
+Run the command:
+python /path/to/syncsource.rc -c {configuration-name}
+
+The -c {configuration-name} can be left off, in which case a
+configuration with the name 'default' will be used.
+
+After that, the transfer will occur. With the rsync-over-ssh
+transfer agent, one rsync per dir-id will be used. rsync output
+is redirected to the console.

+This README describes a sample invocation of lldb-disasm.py whose purpose is to test
+the lldb 'disassemble' command.
+
+This is for the initial checkin of lldb-disasm.py which only reads an executable image and
+dumps the symbol table from the imgae and its dependent libraries. The output was cut off
+since it is too large.

+
+=================
+LLDB Vim Frontend
+=================
+
+Prerequisites
+-------------
+
+This plugin is known to work with the following flavours of Vim:
+
+ * Linux (tested on Ubuntu 12.04/12.10):
+ * vim/gvim (from vim-gnome package version 7.3)
+
+ * Mac OS X (tested on Mountain Lion)
+ * Vim command-line (7.3 from Xcode)
+ * MacVim 7.3
+
+To install the plugin, ensure you have
+ * a working version of lldb on your path, or the environment variable LLDB
+ pointing to the lldb binary you would like to use.
+ * a python-enabled vim (check with ":python print 2")
+
+
+Installation
+------------
+
+1) Install the Vim pathogen plugin (it keeps installed plugins organized):
+
+ https://github.com/tpope/vim-pathogen
+
+ Or, for the impatient:
+
+mkdir -p ~/.vim/autoload ~/.vim/bundle; \
+curl -Sso ~/.vim/autoload/pathogen.vim \
+ https://raw.github.com/tpope/vim-pathogen/master/autoload/pathogen.vim
+
+2) Symlink (or copy) ~/.vim/bundle/vim-lldb to this directory:
+
+ln -sf <lldb-dir>/utils/vim-lldb ~/.vim/bundle/vim-lldb
+
+3) Update your help-tags. Start vim, do:
+
+ :Helptags
+
+4) Have fun!
+
+
+Usage/Getting Help
+------------------
+All LLDB commands (with tab-completion) can be accessed in Vim's
+command mode. Try it out by typing:
+
+:L<tab>
+
+There are several sources of help available:
+
+:help lldb -- Documentation for this plugin
+:Lhelp -- LLDB's built-in help system (i.e lldb 'help' command)
+:Lscript help (lldb) -- Complete LLDB Python API reference

+*lldb.txt* A plugin that enables debugging from your favourite editor
+
+Author: Daniel Malea <daniel.malea at intel.com>
+License: Same terms as Vim itself (see |license|)
+
+INTRODUCTION *lldb*
+
+Installing this plugin enables a set of commands in Vim to control the
+LLDB (http://lldb.llvm.org) debugger.
+
+COMMANDS *lldb-commands*
+
+The LLDB command interpreter is exposed to Vim's command mode using the
+':L' prefix. Tab-completion is available and will cycle through commands.
+Some commands have modified behaviour in Vim; for example, :Lbreakpoint
+with no arguments will set a breakpoint at the current cursor, rather than
+printing the standard help information for the LLDB command 'breakpoint'.
+
+ *lldb-windows*
+
+In addition to the standard commands available under the LLDB interpreter,
+there are also commands to display or hide informational debugger panes.
+
+Windows can be shown or hidden using the ':Lhide <name>' or ':Lshow <name>'
+commands.
+ *lldb-:Lhide*
+:Lhide [windowname] Hide informational debugger pane named 'windowname'.
+
+ *lldb-:Lshow*
+:Lshow [windowname] Show informational debugger pane named 'windowname'.
+
+Possible window name arguments to the Lhide and Lshow commands include:
+
+ * backtrace
+ * breakpoints
+ * disassembly
+ * locals
+ * registers
+ * threads
+ *lldb-:Lattach*
+:Lattach <process-name> Attach to a process by name.
+
+ *lldb-:Ldetach*
+:Ldetach Detach from the current process.
+
+ *lldb-:Ltarget*

+ *lldb-:Lnext*
+:Lnext Step to the next line.
+
+ *lldb-:Lfinish*
+:Lfinish Step out of the current function.
+
+ *lldb-:Lbreakpoint*
