own port namepsace) as the thread identifier to using the system-wide
globally unique thread id as the thread identifier number.
MachThread.cpp keeps both the unique id and the mach port number
for each thread. All layers outside MachThread class use the unique
id with three exceptions: (1) Mach exceptions come in with the port
number (thread_port) which needs to be translated, (2) any calls to
low-level thread_get_state/thread_set_state/thread_suspend etc need
to use the mach port number, (3) MachThreadList::UpdateThreadList
which creates the MachThread objects gets the unique id and passes
it to the MachThread ctor as an argument.
In general, any time nub_thread_t is used, it is now referring to a
unique thread id. Any time a thread_t is used, it is now referring
to a mach port number. There was some interchangability of these
types previously. nub_thread_t has also been changed to a 64-bit
type which necessitated some printf specification string changes.
I haven't been able to test these changes extensively yet but want
to checkpoint the work. The scenarios I've been testing are all
working correctly so while there may be some corner cases I haven't
hit yet, I think it is substantially correct.

This reduces the "ambiguous reference" errors (which are rather strange in C/ObjC) and fixes an assertion hit
with an invalid code test case.

accessible in its declaring class; otherwise we might
fail to apply [class.protected] when considering
accessibility in derived classes.
Noticed by inspection; <rdar://13270329>.
I had an existing test wrong. Here's why it's wrong:
Follow the rules (and notation) of [class.access]p5.
The naming class (N) is B and the context (R) is D::getX.
- 'x' as a member of B is protected, but R does not occur
in a member or friend of a class derived from B.
- There does exist a base class of B, A, which is accessible
from R, and 'x' is accessible at R when named in A because
'x' as a member of A is protected and R occurs in a member
of a class, D, that is derived from A; however, by
[class.protected], the class of the object expression must
be equal to or derived from that class, and A does not
derive from D.

Previously, we had the decisions about inlining spread out
over multiple functions.
In addition to the refactor, this commit ensures
that we will always inline BodyFarm functions as long as the Decl
is available. This fixes false positives due to those functions
not being inlined when no or minimal inlining is enabled such (as
shallow mode).

to control the check for the C 5.2.4.1 / C++ [implimits] restriction on nesting
levels for parentheses, brackets and braces.
Some code with heavy macro use exceeds the default limit of 256, but we don't
want to increase it generally to avoid stack overflow on stack-constrained
systems.

This is a follow-up to r175830, which made sure a temporary object region
created for, say, a struct rvalue matched up with the initial bindings
being stored into it. This does the same for the case in which the AST
actually tells us that we need to create a temporary via a
MaterializeObjectExpr. I've unified the two code paths and moved a static
helper function onto ExprEngine.
This also caused a bit of test churn, causing us to go back to describing
temporary regions without a 'const' qualifier. This seems acceptable; it's
our behavior from a few months ago.

It was incorrectly checking a Function* being an IntrinsicInst* which
isn't possible. It should always have been checking the CallInst* instead.
Added test case for x86 which ensures we only get one constant load.
It was 2 before this change.

There's no apparent reason this code was copied from generated source
into a .cpp. It sets a bad example for those working on other targets
and trying to understand the register info API.

When parsing directives within skipped #if blocks, we don't want to retain
any whitespace. Previously we were just skipping comments, but it's not
possible to skip comments and retain other whitespace. This change matches
the usual behavior for parsing directives (i.e. the behavior outside of
skipped #if blocks).

The 'nobuiltin' attribute is applied to call sites to indicate that LLVM should
not treat the callee function as a built-in function. I.e., it shouldn't try to
replace that function with different code.

The notion of Crossref command has long been forgotten, and there is nothing using CommandObjectCrossref in the current LLDB codebase
However, this was causing a conflict with process plugins and command aliases ending up in an infinite loop under situations such as:
(lldb) command alias monitor process plugin packet monitor
(lldb) process att -n Calendar
Process 28709 stopped
Executable module set to "/Applications/Calendar.app/Contents/MacOS/Calendar".
Architecture set to: x86_64-apple-macosx.
(lldb) command alias monitor process plugin packet monitor
This fixes the loop (and consequent crash) by disposing of Crossref commands and related code

When creating a temporary region (say, when a struct rvalue is used as
the base of a member expr), make sure we account for any derived-to-base
casts. We don't actually record these in the LazyCompoundVal that
represents the rvalue, but we need to make sure that the temporary region
we're creating (a) matches the bindings, and (b) matches its expression.
Most of the time this will do exactly the same thing as before, but it
fixes spurious "garbage value" warnings introduced in r175234 by the use
of lazy bindings to model trivial copy constructors.

On x86-64 platforms, the small code model assumes that code will be loaded below the 2GB boundary. With the static relocation model, the fact that the expression code is initially loaded (in the LLDB debugger address space) above that boundary causes problems. Switching to the JITDefault code model causes the large code model to be used for 64-bit targets and small code model of 32-bit targets.
