Zachary Turner 045fde58d1 Fixes a number of issue related to test portability on Windows.
99% of this CL is simply moving calls to "import pexpect" to a more
narrow scope - i.e. the function that actually runs a particular
test.  This way the test suite can run on Windows, which doesn't have
pexpect, and the individual tests that use pexpect can be disabled on
a platform-specific basis.

Additionally, this CL fixes a few other cases of non-portability.
Notably, using "ps" to get the command line, and os.uname() to
determine the architecture don't work on Windows.  Finally, this
also adds a stubbed out builder_win32 module.

The full test suite runs correctly on Windows after this CL, although
there is still some work remaining on the C++ side to fix one-shot
script commands from LLDB (e.g. script print "foo"), which currently
deadlock.

Todd Fiala 6817df65f0 Modify TestSettings test for stderr.txt/stdout.txt to ignore an
optional path prior to the file base name.

On Linux x86_64 (Ubuntu 12.04) I am sometimes getting a full path
on the stderr.txt.  This changes the test for target.error-path and
target.output-path settings to ignore any optional directory before
the expected file base name.

Greg Clayton 4570d3eba0 Massive test suite cleanup to stop everyone from manually having to compute "mydir" inside each test case.
This has led to many test suite failures because of copy and paste where new test cases were based off of other test cases and the "mydir" variable wasn't updated.

Now you can call your superclasses "compute_mydir()" function with "__file__" as the sole argument and the relative path will be computed for you.

Daniel Malea e0f8f574c7 merge lldb-platform-work branch (and assorted fixes) into trunk
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'

Daniel Malea 7dadf4999a Assorted test suite fixes as a result of GCC 4.8 validation efforts
- disable some TestConcurrentEvents cases (which are affected by llvm.org/pr16714 -- watchpoints in multithreaded programs)
- relax number-of-bp-locations check in TestUniqueTypes/TestUnsignedTypes
- skip TestDataFormatterStdVector cases with GCC 4.8 (known failure due to llvm.org/pr15301)
- workaround for race condition in TestHelloWorld.py
- update TestSettings.py to work on distros (like Fedora) that have /bin/cat hardlinked to /usr/bin/cat

After these changes, the test suite should run cleanly against GCC 4.8 (with DWARF v4)!

Greg Clayton 67cc06366c Reimplemented the code that backed the "settings" in lldb. There were many issues with the previous implementation:
- no setting auto completion
- very manual and error prone way of getting/setting variables
- tons of code duplication
- useless instance names for processes, threads

Now settings can easily be defined like option values. The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing".

Johnny Chen a28b89c700 rdar://problem/10712130
Fixed an issue where backtick char is not properly honored when setting the frame-format variable, like the following:

(lldb) settings set frame-format frame #${frame.index}: ${frame.pc}{ ${module.file.basename}{`${function.name-with-args}${function.pc-offset}}}{ at ${line.file.basename}:${line.number}}\n
(lldb) settings show frame-format
frame-format (string) = "frame #${frame.index}: ${frame.pc}{ `${module.file.basename}{${function.name-with-args}${function.pc-offset}}}{` at ${line.file.basename}:${line.number}}\n"
(lldb)

o CommandObjectSettings.h/.cpp:

  Modify the command object impl to require raw command string instead of parsed command string,
  which also fixes an outstanding issue that customizing the prompt with trailing spaces doesn't
  work.

o Args.cpp:

  During CommandInterpreter::HandleCommand(), there is a PreprocessCommand phase which already
  strips/processes pairs of backticks as an expression eval step.  There's no need to treat
  a backtick as starting a quote.

o TestAbbreviations.py and change_prompt.lldb:

  Fixed incorrect test case/logic.

o TestSettings.py:

  Remove expectedFailure decorator.

Greg Clayton 4c20717a8f General cleanup on the UserSettingsController stuff. There were 5 different
places that were dumping values for the settings. Centralized all of the
value dumping into a single place. When dumping values that aren't strings
we no longer surround the value with single quotes. When dumping values that
are strings, surround the string value with double quotes. When dumping array
values, assume they are always string values, and don't put quotes around
dictionary values.

Greg Clayton 357132eb9a Added the ability to get the min and max instruction byte size for
an architecture into ArchSpec:

uint32_t
ArchSpec::GetMinimumOpcodeByteSize() const;

uint32_t
ArchSpec::GetMaximumOpcodeByteSize() const;

Added an AddressClass to the Instruction class in Disassembler.h.
This allows decoded instructions to know know if they are code,
code with alternate ISA (thumb), or even data which can be mixed
into code. The instruction does have an address, but it is a good
idea to cache this value so we don't have to look it up more than 
once.

Fixed an issue in Opcode::SetOpcodeBytes() where the length wasn't
getting set.

Changed:

	bool
	SymbolContextList::AppendIfUnique (const SymbolContext& sc);

To:
	bool
	SymbolContextList::AppendIfUnique (const SymbolContext& sc, 
									   bool merge_symbol_into_function);

This function was typically being used when looking up functions
and symbols. Now if you lookup a function, then find the symbol,
they can be merged into the same symbol context and not cause
multiple symbol contexts to appear in a symbol context list that
describes the same function.

Fixed the SymbolContext not equal operator which was causing mixed
mode disassembly to not work ("disassembler --mixed --name main").

Modified the disassembler classes to know about the fact we know,
for a given architecture, what the min and max opcode byte sizes
are. The InstructionList class was modified to return the max
opcode byte size for all of the instructions in its list.
These two fixes means when disassemble a list of instructions and dump 
them and show the opcode bytes, we can format the output more 
intelligently when showing opcode bytes. This affects any architectures
that have varying opcode byte sizes (x86_64 and i386). Knowing the max
opcode byte size also helps us to be able to disassemble N instructions
without having to re-read data if we didn't read enough bytes.

Added the ability to set the architecture for the disassemble command.
This means you can easily cross disassemble data for any supported 
architecture. I also added the ability to specify "thumb" as an 
architecture so that we can force disassembly into thumb mode when
needed. In GDB this was done using a hack of specifying an odd
address when disassembling. I don't want to repeat this hack in LLDB,
so the auto detection between ARM and thumb is failing, just specify
thumb when disassembling:

(lldb) disassemble --arch thumb --name main

You can also have data in say an x86_64 file executable and disassemble
data as any other supported architecture:
% lldb a.out
Current executable set to 'a.out' (x86_64).
(lldb) b main
(lldb) run
(lldb) disassemble --arch thumb --count 2 --start-address 0x0000000100001080 --bytes
0x100001080:  0xb580 push   {r7, lr}
0x100001082:  0xaf00 add    r7, sp, #0

Fixed Target::ReadMemory(...) to be able to deal with Address argument object
that isn't section offset. When an address object was supplied that was
out on the heap or stack, target read memory would fail. Disassembly uses
Target::ReadMemory(...), and the example above where we disassembler thumb
opcodes in an x86 binary was failing do to this bug.

Johnny Chen 1a9f4dd5a0 Provided a mechanism for the test class to cleanup after itself once it's done.
This will remove the confusion experienced when previous test runs left some
files (both intermediate or by-product as a result of the test).

lldbtest.TestBase defines a classmethod tearDownClass(cls) which invokes the
platform-specific cleanup() function as defined by the plugin; after that, it
invokes a subclass-specific function classCleanup(cls) if defined; and, finally,
it restores the old working directory.

An example of classCleanup(cls) is in settings/TestSettings.py:

    @classmethod
    def classCleanup(cls):
        system(["/bin/sh", "-c", "rm output.txt"])

where it deletes the by-product "output.txt" as a result of running a.out.
