non-POD/non-trivial object throuugh a C-style varargs. The warning
itself was default-mapped to error, but can be downgraded, but we were
treating it in Sema like a hard error, silently dropping the call.

Instead, treat this problem like a warning, and do what the warning
says we do: abort at runtime. To do so, we fake up a __builtin_trap()
expression that gets evaluated as part of the argument.

variable. InitializationSequence knows the rules for default
initialization, better. Fixes <rdar://problem/8501008>.

prints the file, line, and column of a diagnostic. We currently
support Clang's normal format, MSVC, and Vi formats.

Note that we no longer change the diagnostic format based on
-fms-extensions.

Fix regression in static analyzer's handling of prefix '--' operator.  It was being treated as postfix '--' in C mode.

llvm-svn: 131770

This case is tested by the fact that the modified test produces
significatly worse diagnostics. That's on the list.

Type::isUnsignedIntegerOrEnumerationType(), which are like
Type::isSignedIntegerType() and Type::isUnsignedIntegerType() but also
consider the underlying type of a C++0x scoped enumeration type.

Audited all callers to the existing functions, switching those that
need to also handle scoped enumeration types (e.g., those that deal
with constant values) over to the new functions. Fixes PR9923 /
<rdar://problem/9447851>.

we can recover safely). Add a Fix-It to insert the "inline", just for kicks.

member functions by making sure that they're on the record before
checking for deletion.

Also make sure source locations are valid to avoid crashes.

Unfortunately, the declare-all-implicit-members approach is still
required in order to ensure that dependency loops do not result in
incorrectly deleting functions (since they are to be deleted at the
declaration point per the standard).

For calls returning first-class aggregates, store by element instead of creating aggregate stores in common cases.  This is more friendly to fast-isel.

I have on that's #if 0'ed out, and I don't know why it's failing to
delete the constructor. I'd appreciate if someone familiar with access
