Jyotsna Verma 2ddb2c825f Hexagon: Remove -g option from the assembler command line.

Daniel Jasper 6728fc11bc Change clang-format's affinity for breaking after return types.
Function declarations are now broken with the following preferences:
1) break amongst arguments.
2) break after return type.
3) break after (.
4) break before after nested name specifiers.

Options #2 or #3 are preferred over #1 only if a substantial number of
lines can be saved by that.

John McCall bc48989d0d Drop ObjCIndirectCopyRestoreExprs during template instantiation.
It's a kind of implicit conversion, which we generally drop, but
more importantly it's got very specific placement requirements.

Jordan Rose b1312a5495 Force a load when creating a reference to a temporary copied from a bitfield.
For this source:
  const int &ref = someStruct.bitfield;

We used to generate this AST:

  DeclStmt [...]
  `-VarDecl [...] ref 'const int &'
    `-MaterializeTemporaryExpr [...] 'const int' lvalue
      `-ImplicitCastExpr [...] 'const int' lvalue <NoOp>
        `-MemberExpr [...] 'int' lvalue bitfield .bitfield [...]
          `-DeclRefExpr [...] 'struct X' lvalue ParmVar [...] 'someStruct' 'struct X'

Notice the lvalue inside the MaterializeTemporaryExpr, which is very
confusing (and caused an assertion to fire in the analyzer - PR15694).

We now generate this:

  DeclStmt [...]
  `-VarDecl [...] ref 'const int &'
    `-MaterializeTemporaryExpr [...] 'const int' lvalue
      `-ImplicitCastExpr [...] 'int' <LValueToRValue>
        `-MemberExpr [...] 'int' lvalue bitfield .bitfield [...]
          `-DeclRefExpr [...] 'struct X' lvalue ParmVar [...] 'someStruct' 'struct X'

Which makes a lot more sense. This allows us to remove code in both
CodeGen and AST that hacked around this special case.

The commit also makes Clang accept this (legal) C++11 code:

  int &&ref = std::move(someStruct).bitfield

Anna Zaks e51362e7f7 [analyzer] When reporting a leak in RetainCount checker due to an early exit from init, step into init.
The heuristic here (proposed by Jordan) is that, usually, if a leak is due to an early exit from init, the allocation site will be
a call to alloc. Note that in other cases init resets self to [super init], which becomes the allocation site of the object.

Michael Ilseman e910cc8e07 Improve the diagnostics of the number-reading preprocessor directives.
The GNU line marker directive was sharing code with the #line directive, but some of the warnings/errors were reporting as #line directive diagnostics in both cases.

Previously:
#line 11foo1   ==> "#line directive requires a simple digit sequence"
# 11foo1       ==> "#line directive requires a simple digit sequence"

Now, we get:

Jordan Rose 61e221f68d [analyzer] Replace isIntegerType() with isIntegerOrEnumerationType().
Previously, the analyzer used isIntegerType() everywhere, which uses the C
definition of "integer". The C++ predicate with the same behavior is
isIntegerOrUnscopedEnumerationType().

However, the analyzer is /really/ using this to ask if it's some sort of
"integrally representable" type, i.e. it should include C++11 scoped
enumerations as well. hasIntegerRepresentation() sounds like the right
predicate, but that includes vectors, which the analyzer represents by its
elements.

This commit audits all uses of isIntegerType() and replaces them with the
general isIntegerOrEnumerationType(), except in some specific cases where
it makes sense to exclude scoped enumerations, or any enumerations. These
cases now use isIntegerOrUnscopedEnumerationType() and getAs<BuiltinType>()
plus BuiltinType::isInteger().

isIntegerType() is hereby banned in the analyzer - lib/StaticAnalysis and
include/clang/StaticAnalysis. :-)

Douglas Gregor ebe2db7ed6 <rdar://problem/13584715> Converted constant expressions are expected to have integral values.
We were assuming that any expression used as a converted constant
expression would either not have a folded constant value or would be
an integer, which is not the case for some ill-formed constant
expressions. Because converted constant expressions are only used
where integral values are expected, we can simply treat this as an
error path. If that ever changes, we'll need to widen the interface of
Sema::CheckConvertedConstantExpression() anyway.
