Tamas Berghammer c8fd130a2c Merge dwarf and dsym tests
Currently most of the test files have a separate dwarf and a separate
dsym test with almost identical content (only the build step is
different). With adding dwo symbol file handling to the test suit it
would increase this to a 3-way duplication. The purpose of this change
is to eliminate this redundancy with generating 2 test case (one dwarf
and one dsym) for each test function specified (dwo handling will be
added at a later commit).

Main design goals:
* There should be no boilerplate code in each test file to support the
  multiple debug info in most of the tests (custom scenarios are
  acceptable in special cases) so adding a new test case is easier and
  we can't miss one of the debug info type.
* In case of a test failure, the debug symbols used during the test run
  have to be cleanly visible from the output of dotest.py to make
  debugging easier both from build bot logs and from local test runs
* Each test case should have a unique, fully qualified name so we can
  run exactly 1 test with "-f <test-case>.<test-function>" syntax
* Test output should be grouped based on test files the same way as it
  happens now (displaying dwarf/dsym results separately isn't
  preferable)

Proposed solution (main logic in lldbtest.py, rest of them are test
cases fixed up for the new style):
* Have only 1 test fuction in the test files what will run for all
  debug info separately and this test function should call just
  "self.build(...)" to build an inferior with the right debug info
* When a class is created by python (the class object, not the class
  instance), we will generate a new test method for each debug info
  format in the test class with the name "<test-function>_<debug-info>"
  and remove the original test method. This way unittest2 see multiple
  test methods (1 for each debug info, pretty much as of now) and will
  handle the test selection and the failure reporting correctly (the
  debug info will be visible from the end of the test name)
* Add new annotation @no_debug_info_test to disable the generation of
  multiple tests for each debug info format when the test don't have an
  inferior

Robert Flack 13c7ad9cd2 Replace sys.platform skips in tests with @skip decorators which check against remote platform.
Adds @skipIfPlatform and @skipUnlessPlatform decorators which will skip if /
unless the target platform is in the provided platform list.

Test Plan:
ninja check-lldb shows no regressions.
When running cross platform, tests which cannot run on the target platform are
skipped.

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.

Enrico Granata dc4db5a6eb <rdar://problem/15144376>
This commit reimplements the TypeImpl class (the class that backs SBType) in terms of a static,dynamic type pair

This is useful for those cases when the dynamic type of an ObjC variable can only be obtained in terms of an "hollow" type with no ivars
In that case, we could either go with the static type (+iVar information) or with the dynamic type (+inheritance chain)

With the new TypeImpl implementation, we try to combine these two sources of information in order to extract as much information as possible
This should improve the functionality of tools that are using the SBType API to do extensive dynamic type inspection

Enrico Granata a29cb0bada <rdar://problem/12042982>
This radar extends the notion of one-liner summaries to automagically apply in a few interesting cases

More specifically, this checkin changes the printout of ValueObjects to print on one-line (as if type summary add -c had been applied) iff:
this ValueObject does not have a summary
its children have no synthetic children
its children are not a non-empty base class without a summary
its children do not have a summary that asks for children to show up
the aggregate length of all the names of all the children is <= 50 characters
you did not ask to see the types during a printout
your pointer depth is 0

This is meant to simplify the way LLDB shows data on screen for small structs and similarly compact data types (e.g. std::pair<int,int> anyone?)

Feedback is especially welcome on how the feature feels and corner cases where we should apply this printout and don't (or viceversa, we are applying it when we shouldn't be)

DumpValueObject() 2.0

This checkin restores pre-Xcode5 functionality to the "po" (expr -O) command:
- expr now has a new --description-verbosity (-v) argument, which takes either compact or full as a value (-v is the same as -vfull)
 When the full mode is on, "po" will show the extended output with type name, persistent variable name and value, as in
(lldb) expr -O -v -- foo
(id) $0 = 0x000000010010baf0 {
    1 = 2;
    2 = 3;
}

 When -v is omitted, or -vcompact is passed, the Xcode5-style output will be shown, as in
(lldb) expr -O -- foo
{
    1 = 2;
    2 = 3;
}

- for a non-ObjectiveC object, LLDB will still try to retrieve a summary and/or value to display
(lldb) po 5
5
-v also works in this mode
(lldb) expr -O -vfull -- 5
(int) $4 = 5 

On top of that, this is a major refactoring of the ValueObject printing code. The functionality is now factored into a ValueObjectPrinter class for easier maintenance in the future
DumpValueObject() was turned into an instance method ValueObject::Dump() which simply calls through to the printer code, Dump_Impl has been removed

Test case to follow

Enrico Granata daa0ac48e6 <rdar://problem/12582328>
If you want to define a formatter for "array of Foo of any size", ordinarily you would say

-x "Foo \[[0-9]+\]"

this checkin allows you to instead say "Foo[]" (or "Foo []") and LLDB will automatically create the regular expression and add the -x flag on your behalf

Greg Clayton 3bcdfc0ec1 <rdar://problem/12798131>
Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite.

This fix does the following:
- make sure all short options are treated as "int"
- make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired
- fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates
- fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value

Johnny Chen f1548d4f74 Add a new option to the test driver, -N dsym or -N dwarf, in order to exclude tests decorated with
either @dsym_test or @dwarf_test to be executed during the testsuite run.  There are still lots of
Test*.py files which have not been decorated with the new decorator.

An example:

# From TestMyFirstWatchpoint.py ->
class HelloWatchpointTestCase(TestBase):

    mydir = os.path.join("functionalities", "watchpoint", "hello_watchpoint")

    @dsym_test
    def test_hello_watchpoint_with_dsym_using_watchpoint_set(self):
        """Test a simple sequence of watchpoint creation and watchpoint hit."""
        self.buildDsym(dictionary=self.d)
        self.setTearDownCleanup(dictionary=self.d)
        self.hello_watchpoint()

    @dwarf_test
    def test_hello_watchpoint_with_dwarf_using_watchpoint_set(self):
        """Test a simple sequence of watchpoint creation and watchpoint hit."""
        self.buildDwarf(dictionary=self.d)

Greg Clayton 5009f9d501 Added support for the new ".apple_objc" accelerator tables. These tables are
in the same hashed format as the ".apple_names", but they map objective C
class names to all of the methods and class functions. We need to do this 
because in the DWARF the methods for Objective C are never contained in the
class definition, they are scattered about at the translation unit level and
they don't even have attributes that say the are contained within the class
itself. 

Added 3 new formats which can be used to display data:

    eFormatAddressInfo
    eFormatHexFloat
    eFormatInstruction
    
eFormatAddressInfo describes an address such as function+offset and file+line,
or symbol + offset, or constant data (c string, 2, 4, 8, or 16 byte constants).
The format character for this is "A", the long format is "address".

eFormatHexFloat will print out the hex float format that compilers tend to use.
The format character for this is "X", the long format is "hex float".

eFormatInstruction will print out disassembly with bytes and it will use the
current target's architecture. The format character for this is "i" (which
used to be being used for the integer format, but the integer format also has
"d", so we gave the "i" format to disassembly), the long format is 
"instruction".

Mate the lldb::FormatterChoiceCriterion enumeration private as it should have
been from the start. It is very specialized and doesn't belong in the public 
API.

Enrico Granata 22c55d180d *Some more optimizations in usage of ConstString
*New setting target.max-children-count gives an upper-bound to the number of child objects that will be displayed at each depth-level
  This might be a breaking change in some scenarios. To override the new limit you can use the --show-all-children (-A) option
  to frame variable or increase the limit in your lldbinit file
*Command "type synthetic" has been split in two:
  - "type synthetic" now only handles Python synthetic children providers
  - the new command "type filter" handles filters
  Because filters and synthetic providers are both ways to replace the children of a ValueObject, only one can be effective at any given time.
