actually test-and-compare anything yet. The lldbtest.TestBase has an added
method setTearDownCleanup(dictionary=None) to facilitate running the cleanup
right after each data type test is run. The test case can pass a dictionary
object when registering the test case cleanup.
There is currently only int_type test in the repository.

themselves. Right now, it tests a breakpoint both before and after it has been
resolved.
Updated lldbtest.TestBase.expect() with an additional keyword argument 'exe' (
default to True), which if set to False, will treat the mandatory first argument
as just the string to be matched/or not-matched against the golden input.

of 'breakpoint command add/list/remove' commands to set breakpoint callbacks,
list them, and then remove one.
Modified the lldbtest.TestBase.expect() method to add two additional keyword
arguments:
o matching (default to True), which, if set to False, reverses the semantics of
'expect' to 'expect not'
o patterns (default to None), which specifies a list of regexp patterns to match
against the output from running the command
TestBreakpointCommand.py uses the matching=False and the patterns=[...] expect()
API.

order to customize the running of the test suite. For the time being, the
supported customizations are:
o redirecting stdout and/or stderr
o specifying a list of compilers to build the test programs
o specifying a list of architectures to build the test programs for
Also checked into the examples/test directory some example files which
demonstrate the usage for the above customizations.

Enhanced the lldbtest.TestBase.expect() API to allow an additional keyword arg
named "error". If the client passes "error=True", it signifies that an error
while running the command is expected. The golden input is then compared
against the return object's error output.

build tree relative search path in order to locate the lldb.py module. When
'-i' is present, the test driver relies on the PYTHONPATH environment variable
to locate the lldb.py module.
llvm-svn: 114094
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.

lldb.py module. The priorities to search for are Debug, Release, then
BuildAndIntegration. You can always override this with a valid PYTHONPATH
environment variable before running the test driver.
For example:
$ PYTHONPATH=/Find/My/LLDB/Module/Here ./dotest.py -v .
Python runtime will try to locate the lldb.py module from
/Find/My/LLDB/Module/Here first before trying the Debug, Release, and then
BuildAndIntegration directories.

More clarification for the "os command" output and error as defined in

As a result, both the stl step-in test cases with expectedFailure decorators now
passed.

the binaries.
If the build* function is passed the compiler argument, for example, 'llvm-gcc',
it is passed as a make variable to the make command. Otherwise, we check the
LLDB_CC environment variable; if it is defined, it is passed as a make variable
to the make command.
If neither the compiler keyword argument nor the LLDB_CC environment variable is
specified, no CC make variable is passed to the make command. The Makefile gets
to define the default CC being used.

static class array. It turns out that gcc 4.2 will emit DWARF that correctly
describes the PointType, but it will incorrectly emit debug info for the
"g_points" array where the following things are wrong:
- the DW_TAG_array_type won't have a subrange info
- the DW_TAG_variable for "g_points" won't have a valid byte size, so even
though we know the size of PointType, we can't infer the actual size
of the array by dividing the size of the variable by the number of
elements.
We want to make sure clang and llvm-gcc handle this correctly.

to specify a one-liner (either scripting or lldb command) inline.
Refactored CommandObjectBreakpointCommandAdd::Execute() a little bit and added
some comments.
Sn now, we use:
breakpoint command add -p 1 -o "conditional_break.stop_if_called_from_a()"
to specify a Python one-liner as the callback for breakpoint #1.
llvm-svn: 113672
command for a breakpoint, for example:
(lldb) breakpoint command add -p 1 "conditional_break.stop_if_called_from_a()"
The ScriptInterpreter interface has an extra method:
/// Set a one-liner as the callback for the breakpoint command.
virtual void
SetBreakpointCommandCallback (CommandInterpreter &interpreter,
BreakpointOptions *bp_options,
const char *oneliner);
to accomplish the above.
Also added a test case to demonstrate lldb's use of breakpoint callback command
to stop at function c() only when its immediate caller is function a(). The
following session shows the user entering the following commands:
1) command source .lldb (set up executable, breakpoint, and breakpoint command)
2) run (the callback mechanism will skip two breakpoints where c()'s immeidate caller is not a())
3) bt (to see that indeed c()'s immediate caller is a())
4) c (to continue and finish the program)

involved watching for the objective C built-in types in DWARF and making sure
when we convert the DWARF types into clang types that we use the appropriate
ASTContext types.
Added a way to find and dump types in lldb (something equivalent to gdb's
"ptype" command):
image lookup --type <TYPENAME>
This only works for looking up types by name and won't work with variables.
It also currently dumps out verbose internal information. I will modify it
to dump more appropriate user level info in my next submission.
Hookup up the "FindTypes()" functions in the SymbolFile and SymbolVendor so
we can lookup types by name in one or more images.
Fixed "image lookup --address <ADDRESS>" to be able to correctly show all
symbol context information, but it will only show this extra information when
the new "--verbose" flag is used.

Tests for lldb are written as python scripts which take advantage of the script
bridging provided by LLDB.framework to interact with lldb core.
A specific naming pattern is followed by the .py script to be recognized as
a module which implements a test scenario, namely, Test*.py.
To specify the directories where "Test*.py" python test scripts are located,
you need to pass in a list of directory names. By default, the current
working directory is searched if nothing is specified on the command line.
