it needs to fall back to using the HostArchitecture if a valid one is not
returned. When doing low-level system debugging we may not have a process
(or the remote stub may not support the qProcessInfo packet) in which case
we should fall back to the architecture we determined via qHostInfo.

So, rename the class for what it truly is: a FormattersContainer
Also do a bunch of related text substitutions in the interest of overall naming clarity

of Objective-C classes are completed, and that
variables of Objective-C types have their types
completed when the variables are reported.
This fixes a long-standing issue where ivars did
not show up correctly on 32-bit OS X.

specify a pointer size until code gen. So we just
make all our pointer-sized integer literals 64-bit.
That doesn't seem to hurt anything.

The original code was not completely correct, but a form of
this check is necessary to avoid an infinite recursion on
some unwind cases where a function unwinds to itself with the
same CFA. Ashok thought the recursion would be caught in
RegisterContextLLDB but this one isn't - we still need it here.

In those set of patches, Ashok changed Module::ResolveSymbolContextForAddress
so that if it failed to find a symbol for a pc, it could back up
the pc value by 1 and re-search for a symbol.
His change to RegisterContextLLDB.cpp partially duplicates that
behavior but it also removes the separate case where we find a
Symbol for the pc address but it's the wrong symbol -- we need to
handle this as well as the lookup-by-pc-finds-no-symbol case.
The most obvious fallout from this regression was that lldb on
Mac OS X couldn't backtrace past __assert_rtn() which tail-calls
abort(). e.g.
(lldb) bt
* thread #1: tid = 0x5d6ea1, 0x00007fff8ee80866 libsystem_kernel.dylib`__pthread_kill + 10, queue = 'com.apple.main-thread', stop reason = signal SIGABRT
* frame #0: 0x00007fff8ee80866 libsystem_kernel.dylib`__pthread_kill + 10
frame #1: 0x00007fff8eb5835c libsystem_pthread.dylib`pthread_kill + 92
frame #2: 0x00007fff8852ab1a libsystem_c.dylib`abort + 125
frame #3: 0x00007fff884f49bf libsystem_c.dylib`__assert_rtn + 321
frame #4: 0x0000000100000f2c a.out`main + 124
(lldb) dis -c 3 -s 0x7fff884f49b3
libsystem_c.dylib`__assert_rtn + 309:
0x7fff884f49b3: movq %rax, -0x11b96242(%rip) ; gCRAnnotations + 8
0x7fff884f49ba: callq 0x7fff8854fd2c ; symbol stub for: abort
libsystem_c.dylib`basename:
0x7fff884f49bf: pushq %rbp
(lldb)
in this case, __assert_rtn() is immediately followed by basename() and
the changes in r190812 didn't back up the pc value to get the correct
function name / unwind info.

offsets structure is read & saved in the platform object -- soon
we'll be getting more than the queue name offset out of this
structure so we'll need to reuse the information in other methods.

During testing I observed QEMU send "$T02thread:01;#04" upon connection,
before any command from LLDB. This change from gclayton accepts (and
discards) a packet immediately after sending the initial ack, to flush
the GDB remote pipeline.

While investigating test suite failures when running the test suite remotely, I noticed we had 3 copies of code that launched a process:
1 - in "process launch" command
2 - SBTarget::Launch() with args
3 - SBTarget::Launch() with SBLaunchInfo
"process launch" was launching through the platform if it was supported (this is needed for remote debugging) and the 2 and 3 were not.
Now all code is in one place.

libdispatch aka Grand Central Dispatch (GCD) queues. Still fleshing out the
documentation and testing of these but the overall API is settling down so it's
a good time to check it in.

test_convenience_registers_16bit_with_process_attach fails due to
pr18200. The test has a @expectedFailureFreeBSD decorator, but it
appears this does not catch a RuntimError exception raised in the test
infrastructure, so the test still reports failure. For now just skip
it.

We need to not crash at any cost. We currently detect if any base classes are forward declarations, emit an error string that directs the use to file a compiler bug, and continues by completing the class with no contents. This avoids a clang crash that would usually follow when we call setBase().
llvm-svn: 197108
With this checkin, we use the installed clang compiler to build crashinfo.so from crashinfo.c upon every test suite execution
We also try to cleanup after ourselves, which of course will only work if the test suite does not actually crash
llvm-svn: 197106
Add an hook for the test suite into the OSX-only CrashReporter "App-specific info"
This allows the test suite to set the crash info to the name and file location of every test as the test gets executed
If the test suite crashes, the crash log will then report which test is the culprit, even when not using verbose mode
This only works on OSX, and defaults to not doing anything on other platforms, but OS/platform-specific invocations
can be devised by each individual platform
llvm-svn: 197095
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.
