Argyrios Kyrtzidis 83a6e3bfab [PCH] Deserializing the DeclContext of a template parameter is not safe
until recursive loading is finished.

Otherwise we may end up with a template trying to deserialize a template
parameter that is in the process of getting loaded.

John McCall df25c43599 Rework the visibility computation algorithm in preparation
for distinguishing type vs. value visibility.

The changes to the visibility of explicit specializations
are intentional.  The change to the "ugly" test case is
a consequence of a sensible implementation, and I am happy
to argue that this is better behavior.  Other changes may
or may not be intended;  it is quite difficult to divine
intent from some of the code I altered.

I've left behind a comment which I hope explains the
philosophy behind visibility computation.

Daniel Jasper eb50c676ba Recognize < and > as binary expressions in builder-type calls.
The current heuristic assumes that there can't be binary operators in
builder-type calls (excluding assigments). However, it also excluded
< and > in general, which is wrong. Now they are only excluded if they
are template parameters.

return aaaaaaaaaaaaaaaaa->aaaaa().aaaaaaaaaaaaa()i

Daniel Jasper 23e8e0c7ea Re-enable ConstructorInitializerAllOnOneLineOrOnePerLine option.
This got lost and was untested as the same effect is achieved by
avoiding bin packing, which is active in Google style by default.
However, moving forward, we want more control over the bin packing
option(s) and thus, this flag should work as expected.

Jordan Rose 5bc0dd79e1 [analyzer] Don't assert when mixing reinterpret_cast and derived-to-base casts.
This just adds a very simple check that if a DerivedToBase CastExpr is
operating on a value with known C++ object type, and that type is not the
base type specified in the AST, then the cast is invalid and we should
return UnknownVal.

In the future, perhaps we can have a checker that specifies that this is
illegal, but we still shouldn't assert even if the user turns that checker
off.

...after a host of optimizations related to the use of LazyCompoundVals

Jordan Rose 44d877a8c7 [analyzer] Use collectSubRegionKeys to make removeDeadBindings faster.
Previously, whenever we had a LazyCompoundVal, we crawled through the
entire store snapshot looking for bindings within the LCV's region. Now, we
just ask for the subregion bindings of the lazy region and only visit those.

This is an optimization (so no test case), but it may allow us to clean up
more dead bindings than we were previously.

Jordan Rose ba4a6d10e0 [analyzer] Try constant-evaluation for all variables, not just globals.
In C++, constants captured by lambdas (and blocks) are not actually stored
in the closure object, since they can be expanded at compile time. In this
case, they will have no binding when we go to look them up. Previously,
RegionStore thought they were uninitialized stack variables; now, it checks
to see if they are a constant we know how to evaluate, using the same logic
as r175026.

This particular code path is only for scalar variables. Constant arrays and
structs are still unfortunately unhandled; we'll need a stronger solution
for those.

This may have a small performance impact, but only for truly-undefined
local variables, captures in a non-inlined block, and non-constant globals.
Even then, in the non-constant case we're only doing a quick type check.

Daniel Jasper 2457010b1c Remove the trailing whitespace of formatted lines.
So far, clang-format has always assumed the whitespace belonging to the
subsequent token. This has the negative side-effect that when
clang-format formats a line, it does not remove its trailing whitespace,
as it belongs to the next token.

Thus, this patch fixes most of llvm.org/PR15062.

We are not zapping a file's trailing whitespace so far, as this does not
belong to any token we see during formatting. We need to fix this in a
subsequent patch.

Daniel Jasper 66e9dee707 Get less confused by trailing comma in Google style.
The formatter can now format:
void aaaaaaaaaaaaaaaaaa(int level,
                        double *min_x,
                        double *max_x,
                        double *min_y,
                        double *max_y,

                        double *max_z, ) {
}

Although this is invalid code, it frequently happens during development and
clang-format should be nicer :-).

Rafael Espindola 5bda63f16b merge hasCLanguageLinkage and isExternC. Keep the shorter name.
I added hasCLanguageLinkage while fixing some language linkage bugs some
time ago so that I wouldn't have to check all users of isExternC. It turned
out to be a much longer detour than expected, but this patch finally
merges the two again. The isExternC function now implements just the
standard notion of having C language linkage.

some cases where functions with no language linkage were being treated as having
C language linkage. In particular, don't warn in

extern "C" {
  static NonPod foo();
}

Since getLanguageLinkage checks the language linkage, the linkage computation
cannot use the language linkage. Break the loop by checking just the context
in the linkage computation.
