just using ASTConsumer::HandleCXXStaticMemberVarInstantiation(), don't pass it with
ASTConsumer::HandleTopLevelDecl.
ASTConsumer::HandleTopLevelDecl is intended for user-written top-level decls;
a consumer can treat an instantiated static data member however it wants of course.

In conditional expressions, if the condition is split over multiple
lines, also break before both operands.
This prevents formattings like:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ==
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ? b : c;
Which are bad, because they suggestion incorrect operator precedence:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ==
(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ? b : c);
This lead to the discovery that the expression parser incorrectly
handled conditional operators and that it could also handle semicolons
(which in turn reduced the amount of special casing for for-loops). As a
side-effect, we can now apply the bin-packing configuration to the
sections of for-loops.
llvm-svn: 175973
Also don't break in long include directives as that is not desired.
We can now format:
#include "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
#define LL_FORMAT "ll"
printf("aaaaa: %d, bbbbbbbbb: %" LL_FORMAT "d, cccccccc: %" LL_FORMAT
"d, ddddddddd: %" LL_FORMAT "d\n");
Before, this led to weird results.

Use Optional<CFG*> where invalid states were needed previously. In the one case
where that's not possible (beginAutomaticObjDtorsInsert) just use a dummy
CFGAutomaticObjDtor.
Thanks for the help from Jordan Rose & discussion/feedback from Ted Kremenek
and Doug Gregor.

Weather we should give C language linkage to functions and variables with
internal linkage probably depends on how much code assumes it. The standard
says they should have no language linkage, but gcc and msvc assign them
C language linkage.
This commit removes the hack that was preventing the mangling on static
functions declare in extern C contexts. It is an experiment to see if we
can implement the rules in the standard.
If it turns out that many users depend on these functions and variables
having C language linkage, we should change isExternC instead and try
to convince the CWG to change the standard.

testcase a bit more efficient allow the filename to go through
compilation for compile and not assemble jobs and turn off the
extract for cases where we don't create an object.

the back end and so need to pass it through to codegen.
Also make the methods file static so we can use them in other places.

This Decl shouldn't be the canonical Decl; it should be the Decl used by
the CXXBaseSpecifier in the subclass. Unfortunately, that means continuing
to throw getCanonicalDecl() on all comparisons.
This fixes MemRegion::getAsOffset's use of ASTRecordLayout when redeclarations
are involved.

This is because the order of the entities in the vector can change in some (uncommon) cases.

This may seem counter-intuitive but the POD-like optimization helps when the
vectors grow into multimegabyte buffers. SmallVector calls realloc which knows
how to twiddle virtual memory bits and avoids large copies.

Introduce a new AST Decl node "EmptyDecl" to model empty-declaration. Have attributes from attribute-declaration appertain
to the EmptyDecl node by creating the AST representations of these attributes and attach them to the EmptyDecl node so these
attributes can be sema checked just as attributes attached to "normal" declarations.

Add an ability to specify custom documentation block comment commands via a new
class CommentOptions. The intention is that this class will hold future
customizations for comment parsing, including defining documentation comments
with specific numbers of parameters, etc.
CommentOptions instance is a member of LangOptions.
CommentOptions is controlled by a new command-line parameter
-fcomment-block-commands=Foo,Bar,Baz.

This reduces the "ambiguous reference" errors (which are rather strange in C/ObjC) and fixes an assertion hit

without knowing the complete set of alignment attributes which apply to a

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.
