This is basically a proof-of-concept and starting point for having a
testing-centric tool in LLDB. I'm sure this leaves a lot of room to be
desired, but this at least allows us to have something to build on.
Right now there is only one command, the `module-sections` command, and I
created this command not because it was particularly special, but
because it addressed an immediate use case and was extremely simple.
Run the tool as `lldb-test module-sections <path-to-object>`.
Feel free to add testing related stuff to your heart's content after
this goes in. Implementing the commands themselves takes some work, but
once they're there they can be reused without writing any code and
result in very easy to use and maintain tests.

Summary:
1. Provide single library for all Intel specific hardware features instead
of individual libraries for each feature
2. Added Intel(R) Processor Trace hardware feature in this single library.
Details about the tool implementing this feature is as follows:
Tool developed on top of LLDB to provide its users the execution
trace of the debugged inferiors. Tool's API are exposed as C++ object
oriented interface in a shared library. API are designed especially to be
easily integrable with IDEs providing LLDB as an application debugger.
Entire API is also available as Python functions through a script bridging
interface allowing development of python modules.
This patch also provides a CLI wrapper to use the Tool through LLDB's command
line. Highlights of the Tool and the wrapper are given below:
******************************
Intel(R) Processor Trace Tool:
******************************
- Provides execution trace of the debugged application
- Uses Intel(R) Processor Trace hardware feature (already implemented inside LLDB)
for this purpose
-- Collects trace packets generated by this feature from LLDB, decodes and
post-processes them
-- Constructs the execution trace of the application
-- Presents execution trace as a list of assembly instructions
- Provides 4 APIs (exposed as C++ object oriented interface)
-- start trace with configuration options for a thread/process,
-- stop trace for a thread/process,
-- get the execution flow (assembly instructions) for a thread,
-- get trace specific information for a thread
- Easily integrable into IDEs providing LLDB as application debugger
- Entire API available as Python functions through script bridging interface
-- Allows developing python apps on top of Tool
- README_TOOL.txt provides more details about the Tool, its dependencies, building
steps and API usage
- Tool ready to use through LLDB's command line
-- CLI wrapper has been developed on top of the Tool for this purpose
*********************************
CLI wrapper: cli-wrapper-pt.cpp
*********************************
- Provides 4 commands (syntax similar to LLDB's CLI commands):
-- processor-trace start
-- processor-trace stop
-- processor-trace show-trace-options
-- processor-trace show-instr-log
- README_CLI.txt provides more details about commands and their options

Summary:
The Boundary Table Entries are stored in the application memory and allow
to store boundary info for all the pointers of the program, also those that
otherwise wouldn't fit in the 4 bound registers provided by the HW.
Here is an example of how it works:
* mpx-table show <pointer>
lbound = 0x..., ubound = 0x..., (pointer value = 0x..., metadata = 0x...)
* mpx-table set <pointer>

Rationale:
scripts/Python/modules: android is excluded at a higher level, so no point in
checking here
tools/lldb-mi: lldb-mi builds fine (with some cosmetic tweaks) on android, and
there is no reason it shouldn't.
tools/lldb-server: LLDB_DISABLE_LIBEDIT/CURSES already take the platform into
account, so there is no point in checking again.
I am reasonably confident this should not break the build on any platform, but
I'll keep an eye out on the bots.
llvm-svn: 288661
Summary:
This switches the decision as to whether or not to lldb-server should
be built to check the same flag that was added that controls whether
or not it is added as a dependency to the 'lldb' target.
It also sets that flag on FreeBSD to maintain parity with the existing
build configuration / situation on FreeBSD.

This commit merges lldb-platform and lldb-gdbserver into a single binary
of the same size as each of the previous individual binaries. Execution
mode is controlled by the first argument being either platform or
gdbserver.

Previos version of this patch (see r229148) contained two errors:
* make_symlink_darwin_debug passes 2 arguments into make_symlink, but it required 4 arguments (was fixed by r229159)
* make_symlink doesn't work on OS X
As a quick fix, the r229148 and the r229159 were reverted. Now these errors are fixed.
Summary:
This patch fixes the following tests on OS X:

This patch fixes test_launch_in_terminal test which doesn't work
in OS X since the moment as it was added in r225284. The test fails
because Target::Launch returns the following error: "the darwin-debug
executable doesn't exist at
<output_dir>/lib/python2.7/site-packages/lldb/darwin-debug'".

- Tested with Eclipse, likely to work with other GDB/MI compatible GUIs.
- Some but not all MI commands have been implemented. See MIReadme.txt for more info.
- Written from scratch, no GPL code, based on LLDB Public API.
- Built for Linux, Windows and OSX. Tested on Linux and Windows.
- GDB/MI Command Reference, https://sourceware.org/gdb/onlinedocs/gdb/GDB_002fMI.html
llvm-svn: 208972
CHANGES:
- Thread locking switched from pthreads to C++11 standard library.
- Abstracted platform specific header includes into 'platform.h'.
- Create editline emulator for windows.
- Emulated various platform dependant functions on windows.
TODO:
- User input currently handled by gets_s(), work started on better handler:
see _WIP_INPUT_METHOD define blocks in 'ELWrapper.cpp'.
Aim is to handle 'tab' auto completion on windows.
- Tidy up 'getopt.inc' from lldbHostCommon to serve as LLDB Drivers getopt windows implementation.

Summary:
This merge brings in the improved 'platform' command that knows how to
interface with remote machines; that is, query OS/kernel information, push
and pull files, run shell commands, etc... and implementation for the new
communication packets that back that interface, at least on Darwin based
operating systems via the POSIXPlatform class. Linux support is coming soon.
Verified the test suite runs cleanly on Linux (x86_64), build OK on Mac OS
X Mountain Lion.
Additional improvements (not in the source SVN branch 'lldb-platform-work'):
- cmake build scripts for lldb-platform
- cleanup test suite
- documentation stub for qPlatform_RunCommand
- use log class instead of printf() directly
- reverted work-in-progress-looking changes from test/types/TestAbstract.py that work towards running the test suite remotely.
- add new logging category 'platform'
