failures they know how to tolerate, e.g., out-of-date input files or
configuration/version mismatches. Suppress the corresponding
diagnostics if the client can handle it.
No clients actually use this functionality, yet.

The CFG of the machine function needs to know that the targets of the indirect
branch are successors to the indirect branch.

Per the October 12, 2012 Proposal for annotated disassembly output sent out by
Jim Grosbach this set of changes implements this for X86 and arm. The llvm-mc
tool now has a -mdis option to produced the marked up disassembly and a couple
of small example test cases have been added.

Each option has a set of prefixes. When matching an argument such as
-funroll-loops. First the leading - is removed as it is a prefix. Then
a lower_bound search for "funroll-loops" is done against the option table by
option name. From there each option prefix + option name combination is tested
against the argument.
This allows us to support Microsoft style options where both / and - are valid
prefixes. It also simplifies the cases we already have where options come in
both - and -- forms. Almost every option for gnu-ld happens to have this form.

Fixed a crasher where if an invalid SBTarget was passed to:
lldb::addr_t
SBAddress::GetLoadAddress (const SBTarget &target) const;
We would crash.

manager block and input-file information in the control block. The
source manager entries now point back into the control block. Input
files are now lazily deserialized (if validation is disabled). Reduces
Cocoa's PCH by the ~70k I added when I introduced the redundancy in
r166251.

- This is an assumption that is currently hardwired into the backend, we need
to do this in order for the frontend and backend to agree.

Given our implementation of ValueObjects we could have a scenario where a ValueObject has a dynamic type of Foo* at one point, and then its dynamic type changes to Bar*
If Bar* has synthetic children enabled, by the time we figure that out, our public API is already vending SBValues wrapping a DynamicVO, instead of a SyntheticVO and there was
no trivial way for us to change the SP inside an SBValue on the fly
This checkin reimplements SBValue in terms of a wrapper, ValueImpl, that allows this substitutions on-the-fly by overriding GetSP() to do The Right Thing (TM)
As an additional bonus, GetNonSyntheticValue() now works, and we can get rid of the ForceDisableSyntheticChildren idiom in ScriptInterpreterPython
Lastly, this checkin makes sure the synthetic VOs get the correct m_value and m_data from their parents (prevented summaries from working in some cases)

Unreachable blocks can have invalid instructions. For example,
jump threading can produce self-referential instructions in
unreachable blocks. Also, we should not be spending time
optimizing unreachable code. Fixes PR14133.

Patch by Quentin Colombet <qcolombet@apple.com>
Original description:
"""
The attached patch is the first step to have a better control on Oz related optimizations.
The Oz optimization level focuses on code size, thus I propose to add an attribute called ForceSizeOpt.

Allow type searches to specify a type keyword when searching for type. Currently supported type keywords are: struct, class, union, enum, and typedef.
So now you can search for types with a string like "struct foo".

very small but very important bugfix:
bool shouldExplore(Use *U) {
Value *V = U->get();
if (isa<CallInst>(V) || isa<InvokeInst>(V))
[...]
should have read:
bool shouldExplore(Use *U) {
Value *V = U->getUser();
if (isa<CallInst>(V) || isa<InvokeInst>(V))
Fixes PR14143!

This change ensures that isl is only detected if it includes code generation
support. This allows us to remove a lot of conditional compilation and also
avoids missing test cases in case the feature is not available.

On Linux there is no difference between shared modules and shared libaries, both
are '.so' files. However, on darwin only shared modules are '.so' files. Shared
libraries have the '.dynlib' suffix.
Fix test cases on darwin by expecting a shared module suffix for Polly instead
of a shared library suffix.
This fixes PR14135

This is important for vectors of pointers because only DataLayout,
not the underlying vector type, knows how to calculate the size
of the pointers in the vector. Fixes PR14138.

It passes all tests, produces better results than the old code but uses the
wrong pass, LoopDependenceAnalysis, which is old and unmaintained. "Why is it
still in tree?", you might ask. The answer is obviously: "To confuse developers."
Just swapping in the new dependency pass sends the pass manager into an infinte
loop, I'll try to figure out why tomorrow.
