Ed Maste fac86fd06f tests: Mark expected FreeBSD failures due to pr16696
Live debugging of threaded inferiors is currently unimplemented for
FreeBSD.

Ed Maste 8ed8689132 test_iter_registers is expected to fail on FreeBSD
Added comment to llvm.org/pr14600 that it fails on FreeBSD in the same way
as Linux.

Daniel Malea e8bdd1f5c0 Clean up linux test decorators and add links to known bugs
- s/skipOnLinux/skipIfLinux/ to match style of every other decorator
- linkify bugizilla/PR numbers in comments

No intended change in functionality.

Daniel Malea 2745d8467b Update test scripts and Makefiles to allow testing with GCC:
- introduce new variable ARCHFLAG in make/Makefile.rules to switch between "-arch" on Mac and "-m" everywhere else
- update testcase makefiles to use LD_EXTRAS instead of LDFLAGS (the former interacts with Makefile.rules badly)
- special treatment for gcc 4.6: replace "-std=c++11" with "-std=c++0x" as the former is not handled correctly
- remove hardcoded "-arch" from test Makefile

This patch should not have any effect on lldb on Mac OS X.

Greg Clayton 7fdf9ef15d Added a new Host class: ReadWriteLock
This abstracts read/write locks on the current host system. It is currently backed by pthread_rwlock_t objects so it should work on all unix systems.

We also need a way to control multi-threaded access to the process through the public API when it is running. For example it isn't a good idea to try and get stack frames while the process is running. To implement this, the lldb_private::Process class now contains a ReadWriteLock member variable named m_run_lock which is used to control the public process state. The public process state represents the state of the process as the client knows it. The private is used to control the actual current process state. So the public state of the process can be stopped, yet the private state can be running when evaluating an expression for example. 

Adding the read/write lock where readers are clients that want the process to stay stopped, and writers are clients that run the process, allows us to accurately control multi-threaded access to the process.

Switched the SBThread and SBFrame over to us shared pointers to the ExecutionContextRef class instead of making their own class to track this. This fixed an issue with assigning on SBFrame to another and will also centralize the code that tracks weak references to execution context objects into one location.

Greg Clayton fe42ac4d0a Cleaned up the SBType.h file to not include internal headers and reorganized
the SBType implementation classes.

Fixed LLDB core and the test suite to not use deprecated SBValue APIs.

Added a few new APIs to SBValue:

    int64_t
    SBValue::GetValueAsSigned(int64_t fail_value=0);

    uint64_t
    SBValue::GetValueAsUnsigned(uint64_t fail_value=0)

Johnny Chen 5ccbccfce0 Add a @benchmarks_test decorator for test method we want to categorize as benchmarks test.
The test driver now takes an option "+b" which enables to run just the benchmarks tests.
By default, tests decorated with the @benchmarks_test decorator do not get run.

Add an example benchmarks test directory which contains nothing for the time being,
just to demonstrate the @benchmarks_test concept.

For example,

$ ./dotest.py -v benchmarks

...

----------------------------------------------------------------------
Collected 2 tests

1: test_with_gdb (TestRepeatedExprs.RepeatedExprssCase)
   Test repeated expressions with gdb. ... skipped 'benchmarks tests'
2: test_with_lldb (TestRepeatedExprs.RepeatedExprssCase)
   Test repeated expressions with lldb. ... skipped 'benchmarks tests'

----------------------------------------------------------------------
Ran 2 tests in 0.047s

OK (skipped=2)
$ ./dotest.py -v +b benchmarks

...

----------------------------------------------------------------------
Collected 2 tests

1: test_with_gdb (TestRepeatedExprs.RepeatedExprssCase)
   Test repeated expressions with gdb. ... running test_with_gdb
benchmarks result for test_with_gdb
ok
2: test_with_lldb (TestRepeatedExprs.RepeatedExprssCase)
   Test repeated expressions with lldb. ... running test_with_lldb
benchmarks result for test_with_lldb
ok

----------------------------------------------------------------------
Ran 2 tests in 0.270s

OK

Also mark some Python API tests which are missing the @python_api_test decorator.

Johnny Chen 1d3e880c2c Passing in os.ctermid() as the arg for SBTarget.Launch(...) for stdin_path, stdout_path, and stderr_path
is just wrong and resulted in the inferior's output getting mixed into the GDB remote communication's
log file.  Change all test cases to not pass os.ctermid() and either use SBTarget.LaunchSimple() or
SBTarget.Launch() and pass None as stdin_path/stdout_path/srderr_path to use a pseudo terminal.

Johnny Chen 0d4f6dd01e o lldbutil.py:
For the print_stacktrace(thread, string_buffer = False) function, if we have debug info
  for a frame function, let's also emit the args for the current function.

o TestFrameUtils.py:

  Add stronger assertTrue for frame0's args.

o TestPrintStackTraces.py:

  Launch the inferior with ["abc", "xyz"] and expect '(int)argc=3' in the stack traces, since
  by design the inferior is built with debug info.

Johnny Chen 5a0bee7c5f The extra burden for the Python API test case to assign its process object to self.process
in order to have its process cleaned up (terminated) upon tearDown is gone for good.
Let's simplify a bunch of Python API test cases.

Johnny Chen 112f5696fb Add truth value testing to those lldb Python objects with the IsValid() method definitions.
object.__nonzero__(self) is called to implement truth value testing and the built-in operation bool(),
via a simple delegation to self.IsValid().

Change tests under python_api/lldbutil to utilize this mechanism.

Johnny Chen fac7b3aae6 Add implementation of built-in function len() for those lldb containers with
unambiguous iteration support.  So that we could, for example:

    ...

    REGs = lldbutil.get_GPRs(frame)
    print "Number of general purpose registers: %d" % len(REGs)
    for reg in REGs:
        print "%s => %s" %(reg.GetName(), reg.GetValue())

    ...

Johnny Chen ad7372c538 Add two utility functions:
o get_parent_frame(frame)
    o get_args_as_string(frame)

to lldbutil.py and create TestFrameUtils.py to exercise the utils.
Plus re-arrange the test/python_api/lldbutil to have three directories
for testing iteration, process stack traces, and the just added frame utils.

Johnny Chen 64ff7e6eee Add a utility function get_registers(frame, kind) to get the registers of a given frame and of a given kind.
Also add three convenience functions get_GPRs(frame), get_FPRs(frame), and get_ESRs(frame) to get the general
purpose registers, the floating point registers, and the exception state registers.

Add TestRegistersIterator.py to test these added functions of lldbutil.py.

Johnny Chen 0f023fa4af Add the Python rich comparison methods for SBBreakpoint, where GetID() returns
the breakpoint ID and provides the semantics needed for '==' and '!='.  And
modify LLDBIteratorTestCase.lldb_iter_2() to use '==' between two SBBreakpoint's.

Johnny Chen fbc0d27144 Move the iteration protocol of lldb objects to the auto-generated lldb Python module.
This is so that the objects which support the iteration protocol are immediately obvious
from looking at the lldb.py file.

SBTarget supports two types of iterations: module and breakpoint.  For an SBTarget instance,
you will need to issue either:

    for m in target.module_iter()

or

    for b in target.breakpoint_iter()

For other single iteration protocol objects, just use, for example:

    for thread in process:
        ID = thread.GetThreadID()
        for frame in thread:
            frame.Disassemble()
            ....

Johnny Chen b2e1a5c998 Add a utility function smart_iter() which has knowledge of the getsize and the getelem
method names of all the lldb container objects and returns an iterator object when
passed an eligible lldb container object.

Example:

    from lldb_util import smart_iter
    for thread in smart_iter(process):
        ID = thread.GetThreadID()
        if thread.GetStopReason() == lldb.eStopReasonBreakpoint:
            stopped_due_to_breakpoint = True
        for frame in smart_iter(thread):
            self.assertTrue(frame.GetThread().GetThreadID() == ID)
        ...

Add a test case for lldb.smart_iter().

SBThread, SBThread contains SBFrame, etc.
