Disallowing deriving from classes that have private virtual base classes
except in instances where the deriving class would be able to cast
itself to the private virtual base via a different derivation.

The element passed to push_back is not copied before the vector reallocates.
The client needs to copy the element first before passing it to push_back.

No test case, will be tested by follow-up swift scheduler model change (it
segfaults without this change).

Remove the debugserver "--open-connection" option and obey the hostname that is passed into debugserver.

you can now specify:

debugserver host:port
debugserver port
debugserver /path/to/file

When "host" is specified, we will only accept connections from that host. If host is not specified, we default to "localhost".

Jeffrey Yasskin volunteered to benchmark the vectorizer on -O2 or -Os when compiling chrome. This patch adds a new flag to enable vectorization on all levels and not only on -O3. It should go away once we make a decision.

Address::GetSection() turns a weak pointer to a shared pointer which is a little slow.  So in Address::operator== & != do the
cheap GetOffset() comparison first and only compare the sections if that is true.

The function in which we were doing it used to be conditionalized. Add a new unconditional
cleanup step.

This fixes PR16227 (radar://14073870) - a crash when generating html output for one of the test files.

Previously our edges were completely broken here; now, the final result
is a very simple set of edges in most cases: one up to the "for" keyword
for context, and one into the body of the loop. This matches the behavior
for ObjC for-in loops.

In the AST, however, CXXForRangeStmts are handled very differently from
ObjCForCollectionStmts. Since they are specified in terms of equivalent
statements in the C++ standard, we actually have implicit AST nodes for
all of the semantic statements. This makes evaluation very easy, but
diagnostic locations a bit trickier. Fortunately, the problem can be
generally defined away by marking all of the implicit statements as
part of the top-level for-range statement.

One of the implicit statements in a for-range statement is the declaration
of implicit iterators __begin and __end. The CFG synthesizes two
separate DeclStmts to match each of these decls, but until now these
synthetic DeclStmts weren't in the function's ParentMap. Now, the CFG
keeps track of its synthetic statements, and the AnalysisDeclContext will
make sure to add them to the ParentMap.

Seems we emit the parameter ordering number (spuriously named 'arg
number') in the debug info, so there's no need to search through the
variable list to figure out the parameter ordering. This implementation
does 'always' do the work, even in non-optimized debug info (the
previous implementation checked the existence of the 'variables' list on
the subprogram which is only present in optimized builds).

No intended functionality change.

First step toward supporting header modifications: adding a flag that turns on
such modifications. Eventually header modifications will be on by default but
until all the kinks can be worked out, they must be explicitly enabled.

that is patterned after its parent TestInferiorCrashing.py.

- The xfail decorator limits the xfail to tool-chains that support this compiler option.
- Included a TODO concerning the platform-specific behavior when 'next' is issued after a crash.
- Toggling -fomit-frame-pointer results in an xpass as mentioned in pr15415.

from the LC_DATA_IN_CODE load command.  And when disassembling print
the data in code formatted for the kind of data it and not disassemble those
bytes.

I added the format specific functionality to the derived class MachOObjectFile
since these tables only appears in Mach-O object files. This is my first
attempt to modify the libObject stuff so if folks have better suggestions
how to fit this in or suggestions on the implementation please let me know.
