8258705dbd Clang sometimes emits "objc_object*" rather than "id"
for id types with protocols on them.  We detect this
and report "id" instead.

Also added a testcase.

5deaa4c902 Made LLDB compile with LLVM top-of-tree again.
The results from Clang name lookups changed to
be ArrayRefs, so I had to change the way we
check for the presence of a result and the way
we iterate across results.

7be70e8528 This patch removes the SymbolFileSymtab support
for reporting class types from Objective-C runtime
class symbols.  Instead, LLDB now queries the 
Objective-C runtime for class types.

We have also added a (minimal) Objective-C runtime
type vendor for Objective-C runtime version 1, to 
prevent regressions when calling class methods in
the V1 runtime.

Other components of this fix include:

- We search the Objective-C runtime in a few more
  places.

- We enable enumeration of all members of
  Objective-C classes, which Clang does in certain
  circumstances.

- SBTarget::FindFirstType and SBTarget::FindTypes
  now query the Objective-C runtime as needed.

- I fixed several test cases.

f17b5ac6e1 <rdar://problem/11961650>
Update the debugserver "qProcessInfo" implementation to return the
cpu type, cpu subtype, OS and vendor information just like qHostInfo
does so lldb can create an ArchSpec based on the returned values.

Add a new GetProcessArchitecture to GDBRemoteCommunicationClient akin
to GetHostArchitecture.  If the qProcessInfo packet is supported,
GetProcessArchitecture will return the cpu type / subtype of the 
process -- e.g. a 32-bit user process running on a 64-bit x86_64 Mac
system. 

Have ProcessGDBRemote set the Target's architecture based on the 
GetProcessArchitecture when we've completed an attach/launch/connect.

to report a structure with an array of size 1
at the end without accounting for that array
when reporting the struct's total size to Clang.

When using the same-device optimization for shared cache libraries, if
we have an invalid load address for __LINKEDIT, don't try to read
anything out of lldb's own address space.  Reading it out of the remote
address space will fail gracefully if we have bad addresses but reading
it out of lldb's own address space will result in a crash.

b9d5df58d4 <rdar://problem/12820334>
I modified the "Args::StringtoAddress(...)" function to be able to evaluate address expressions. This is now used for any command line arguments or options that takes addresses like:

memory read <addr> [<end-addr>]
memory write <addr>
breakpoint set --address <addr>
disassemble --start-address <addr> --end-address <addr>

It calls the expression parser to evaluate the address expression and will also work around the issue where the compiler doesn't like to add offsets to function pointers (which is what happens when you try to evaluate "main + 12"). So there is a temp fix in the Args::StringtoAddress() to work around this until we can get special compiler support for debug expressions with function pointers.

faa0bb3fa1 Rewrote the bitfield logic. Major changes include:
- Removed the BitfieldMap class because it is unnecessary.
  We now just track the most recently added field.

- Moved the code that calculates bitfield widths so it
  can also be used to determine whether it's necessary
  to insert anonymous fields.

- Simplified the anonymous field calculation code into
  three cases (two of which are resolved identically).

- Beefed up the bitfield testcase.

65d57a3d2a Don't re-add kexts and the kernel each time we get a notification
that kexts were newly added.

The Darwin userland dynamic loader provides lldb with a list of 
newly-added or newly-removed binaries but in the kernel case we
only know that something has changed.  DynamicLoaderDarwinKernel
really needs to maintain its own persistent list of kexts that 
it has been notified about (most importantly, it will not detect
kext unlods) but for now we'll at least avoid re-adding an already
present kext.
