the test has passed in the last 300 runs, enabling to see what the build bot says. Also,
downgrading skipIfGcc to XFAIL, with plans of enabling it in the future if it shows to be
working.

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.

The issue was the previous code tried to stop on the following code in main.c:
21 // Stop here and set values
22 printf ("Val - %d Mine - %d, %d, %llu. Ptr - %d, %d, %llu\n",
23 val,
24 mine.first_val, mine.second_val, mine.third_val,
25 ptr->first_val, ptr->second_val, ptr->third_val);
We we set a source regex breakpoint on "// Stop here and set values" we would set a breakpoint on line 22 as expected.
The problem is the most recent clang compiler generates a line table like this
0x1000: main.c:23 // Loading of "val" into a register
0x1010: main.c:24 // Load mine.first_val, mine.second_val, mine.third_val values into registers or on the stack
0x1020: main.c:25 // Load ptr->first_val, ptr->second_val, ptr->third_val values into registers or on the stack
0x1030: main.c:22 // Call to printf
In this test, we run to line 22, then we use python to modify the value of "val" and then continue to another breakpoint and try to read the STDOUT from the printf to verify the values changed correctly.
With the above line table the value for "val" had already been loaded into a register so the string from printf would be incorrect.
Doing an easy fix for now by changing the code to:
21 // Stop here and set values
22 printf ("Val - %d Mine - %d, %d, %llu. Ptr - %d, %d, %llu\n", val,
23 mine.first_val, mine.second_val, mine.third_val,
24 ptr->first_val, ptr->second_val, ptr->third_val);
Now we get a line table entry for line 22 that is before any locals are read from the stack into registers.
I need to follow up with the compiler guys and see if we can get a fix for this as anyone setting file + line breeakpoints might be very surprised to have code from lines below the current line already have had their code run.

This test has intermittently failed on FreeBSD for quite some time when
run as part of the full test suite. It generally passes when run by
itself. Mark as expected failure for now to reduce buildbot noise.

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.

This test is incorrect as functions that return lldb.SBThread objects never return None, they just return lldb.SBThread objects that contain invalid opaque classes.

Audit lldb API impl for places where we need to perform a NULL check
Add a NULL check for SBValue.CreateValueFromExpression().

Add code to test case to create an evil linked list with:
task_evil -> task_2 -> task_3 -> task_evil ...
and to check that the linked list iterator only iterates 3 times.
llvm-svn: 137291
where an empty linked list is represented as a value object with a NULL value, instead of a special value
object which 'points' to NULL.
Also modifies the test case to comply.

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:
