Commit a bit of a hack to fully handle the situation where variables are
...
marked explicitly as uninitialized through direct self initialization:
int x = x;
With r128894 we prevented warnings about this code, and this patch
teaches the analysis engine to continue analyzing subsequent uses of
'x'. This should wrap up PR9624.
There is still an open question of whether we should suppress the
maybe-uninitialized warnings resulting from variables initialized in
this fashion. The definitely-uninitialized uses should always be warned.

Added *hidden* flags -print-options and -print-all-options so
...
developers can see if their driver changed any cl::Option's. The
current implementation isn't perfect but handles most kinds of
options. This is nice to have when decomposing the stages of
compilation and moving between different drivers. It's also a good
sanity check when comparing results produced by different command line
invocations that are expected to produce the comparable results.
Note: This is not an attempt to prolong the life of cl::Option. On the
contrary, it's a placeholder for a feature that must exist when
cl::Option is replaced by a more appropriate framework. A new
framework needs: a central option registry, dynamic name lookup,
non-global containers of option values (e.g. per-module,
per-function), *and* the ability to print options values and their defaults at
any point during compilation.

Fix PR9624 by explicitly disabling uninitialized warnings for direct self-init:
...
int x = x;
GCC disables its warnings on this construct as a way of indicating that
the programmer intentionally wants the variable to be uninitialized.
Only the warning on the initializer is turned off in this iteration.
This makes the code a lot more ugly, but starts commenting the
surprising behavior here. This is a WIP, I want to refactor it
substantially for clarity, and to determine whether subsequent warnings
should be suppressed or not.

Fix PR 9626 (duplicated self-init warnings under -Wuninitialized) with numerous CFG and UninitializedValues analysis changes:
...
1) Change the CFG to include the DeclStmt for conditional variables, instead of using the condition itself as a faux DeclStmt.
2) Update ExprEngine (the static analyzer) to understand (1), so not to regress.
3) Update UninitializedValues.cpp to initialize all tracked variables to Uninitialized at the start of the function/method.
4) Only use the SelfReferenceChecker (SemaDecl.cpp) on global variables, leaving the dataflow analysis to handle other cases.
The combination of (1) and (3) allows the dataflow-based -Wuninitialized to find self-init problems when the initializer
contained control-flow.

Fix an error in TreeTransform where we failed to copy the TemplateName's

location into a TemplateSpecializationTypeLoc. These were found using
a hand-written program to inspect every source location in
TemplateSpecializationTypeLocs and Valgrind. I don't know of any way to
test them in Clang's existing test suite sadly.
Example code that triggers the ElaboratedType case:
template <typename T> struct X1 {
template <typename U> struct X1_1 {
int x;
};
};
template <typename T, typename U> struct X2 {
typename X1<T>::template X1_1<U> B;
};
X2<char, int> x2;
The other fix was simply spotted by inspection. I audited all constructions of
[Dependent]TemplateSpecializationTypeLocs in TreeTransform.h, and the rest set
the TemplateNameLoc properly.

Revert r128691, "IRgen: Improve GCC compatibility when dealing with packed
...
arrays by propagating", it's breaking test in ways I don't understand yet.

IRgen: Improve GCC compatibility when dealing with packed arrays by propagating
...
the array alignment to the array access.
- This is more or less the best we can do without having alignment present in
the type system, but is a long way from truly matching how GCC handles this.

-Wuninitialized should not warn about variables captured by blocks as byref.
...
Note this can potentially be enhanced to detect if the __block variable
is actually written by the block, or only when the block "escapes" or
is actually used, but that requires more analysis than it is probably worth
for this simple check.

Add security syntax checker for strcpy() which causes the Static Analyzer to generate a warning any time the strcpy() function is used with a note suggesting to use a function which provides bounded buffers.

Adding Static Analyzer checker for mempcpy().
...
Models mempcpy() so that if length is NULL the destination pointer is returned. Otherwise, the source and destination are confirmed not to be NULL and not overlapping. Finally the copy is validated to not cause a buffer overrun and the return value is bound to the address of the byte after the last byte copied.

After much contemplation, I've decided that we probably shouldn't "unique"
...
__block object copy/dispose helpers for C++ objects with those for
different variables with completely different semantics simply because
they happen to both be no more aligned than a pointer.
Found by inspection.
Also, internalize most of the helper generation logic within CGBlocks.cpp,
and refactor it to fit my peculiar aesthetic sense.
