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
...

- Completely new implementation of SBType
- Various enhancements in several other classes
Python synthetic children providers for std::vector<T>, std::list<T> and std::map<K,V>:
- these return the actual elements into the container as the children of the container
- basic template name parsing that works (hopefully) on both Clang and GCC
- find them in examples/synthetic and in the test suite in functionalities/data-formatter/data-formatter-python-synth
New summary string token ${svar :
- the syntax is just the same as in ${var but this new token lets you read the values
coming from the synthetic children provider instead of the actual children
- Python providers above provide a synthetic child len that returns the number of elements
into the container
Full bug fix for the issue in which getting byte size for a non-complete type would crash LLDB
Several other fixes, including:
- inverted the order of arguments in the ClangASTType constructor
- EvaluationPoint now only returns SharedPointer's to Target and Process
- the help text for several type subcommands now correctly indicates argument-less options as such

end of list test function as __eol_test__.
The simple example can be reduced to:
for t in task_head.linked_list_iter('next'):
print t
Modify the test program to exercise the API for both cases: supplying or not
supplying an end of list test function.

too complex in the test case. We can just simply test that the SBValue object
is a valid object and it does not correspond to a null pointer in order to say
that EOL has not been reached.
Modify the test case and the lldb.py docstring to have a more compact test
function.

to iterate through an SBValue instance by treating it as the head of a linked
list. API program must provide two args to the linked_list_iter() method:
the first being the child member name which points to the next item on the list
and the second being a Python function which an SBValue (for the next item) and
returns True if end of list is reached, otherwise it returns False.
For example, suppose we have the following sample program.
#include <stdio.h>
class Task {
public:
int id;
Task *next;
Task(int i, Task *n):
id(i),
next(n)
{}
};
int main (int argc, char const *argv[])
{
Task *task_head = new Task(-1, NULL);
Task *task1 = new Task(1, NULL);
Task *task2 = new Task(2, NULL);
Task *task3 = new Task(3, NULL); // Orphaned.
Task *task4 = new Task(4, NULL);
Task *task5 = new Task(5, NULL);
task_head->next = task1;
task1->next = task2;
task2->next = task4;
task4->next = task5;
int total = 0; // Break at this line
Task *t = task_head;
while (t != NULL) {
if (t->id >= 0)
++total;
t = t->next;
}
printf("We have a total number of %d tasks\n", total);
return 0;
}
The test program produces the following output while exercising the linked_list_iter() SBVAlue API:
task_head:
TypeName -> Task *
ByteSize -> 8
NumChildren -> 2
Value -> 0x0000000106400380
ValueType -> local_variable
Summary -> None
IsPointerType -> True
Location -> 0x00007fff65f06e60
(Task *) next = 0x0000000106400390
(int) id = 1
(Task *) next = 0x00000001064003a0
(Task *) next = 0x00000001064003a0
(int) id = 2
(Task *) next = 0x00000001064003c0

API.
SBTarget changes include changing:
bool
SBTarget::ResolveLoadAddress (lldb::addr_t vm_addr,
lldb::SBAddress& addr);
to be:
lldb::SBAddress
SBTarget::ResolveLoadAddress (lldb::addr_t vm_addr);
SBAddress can how contruct itself using a load address and a target
which can be used to resolve the address:
SBAddress (lldb::addr_t load_addr, lldb::SBTarget &target);
This will actually just call the new SetLoadAddress accessor:
void
SetLoadAddress (lldb::addr_t load_addr,
lldb::SBTarget &target);
This function will always succeed in making a SBAddress object
that can be used in API calls (even if "target" isn't valid).
If "target" is valid and there are sections currently loaded,
then it will resolve the address to a section offset address if
it can. Else an address with a NULL section and an offset that is
the "load_addr" that was passed in. We do this because a load address
might be from the heap or stack.

represent pointers and arrays by adding an extra parameter to the
SBValue
SBValue::GetChildAtIndex (uint32_t idx,
DynamicValueType use_dynamic,
bool can_create_synthetic);
The new "can_create_synthetic" will allow you to create child values that
aren't actually a part of the original type. So if you code like:
int *foo_ptr = ...
And you have a SBValue that contains the value for "foo_ptr":
SBValue foo_value = ...
You can now get the "foo_ptr[12]" item by doing this:
v = foo_value.GetChiltAtIndex (12, lldb.eNoDynamicValues, True);
Normall the "foo_value" would only have one child value (an integer), but
we can create "synthetic" child values by treating the pointer as an array.
Likewise if you have code like:
int array[2];
array_value = ....
v = array_value.GetChiltAtIndex (0); // Success, v will be valid
v = array_value.GetChiltAtIndex (1); // Success, v will be valid
v = array_value.GetChiltAtIndex (2); // Fail, v won't be valid, "2" is not a valid zero based index in "array"
But if you use the ability to create synthetic children:
v = array_value.GetChiltAtIndex (0, lldb.eNoDynamicValues, True); // Success, v will be valid
v = array_value.GetChiltAtIndex (1, lldb.eNoDynamicValues, True); // Success, v will be valid
v = array_value.GetChiltAtIndex (2, lldb.eNoDynamicValues, True); // Success, v will be valid

clang/gcc/llvm-gcc. If the first breakpoint is due to stop at an inlined
frame, test that the call site corresponds to where it should be. Also add
an expecr for a second break stop, if the first break stop corresponds to an
inlined call frame #0.

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.

rdar://problem/9700873 has been updated to reflect the latest status. The dwarf case
now does not seg fault if the inferior is not started; instead, for dwarf case, the
value retrieved from the global variable is None.

Add a usage example of SBEvent APIs.
o SBEvent.h and SBListener.h:
Add method docstrings for SBEvent.h and SBListener.h, and example usage of SBEvent into
the class docstring of SBEvent.
o lldb.swig:
Add typemap for SBEvent::SBEvent (uint32_t event, const char *cstr, uint32_t cstr_len)
so that we can use, in Python, obj2 = lldb.SBEvent(0, "abc") to create an SBEvent.

Fixed crashes for SBValue fuzz calls.
And change 'bool SBType::IsPointerType(void)' to
'bool SBType::IsAPointerType(void)' to avoid name collision with the static 'bool SBType::IsPointerType(void *)'
function, which SWIG cannot handle.
