The Preprocessor::Initialize() function already offers a clear interface to
achieve this, further reducing the confusing number of states a newly
constructed preprocessor can have.

These calls to ConsumeCodeCompletionToken() caused parsing to continue
needlessly when an immediate cutOffParsing() would do.
Document the function to clarify its correct usage.

Also improve this code in general by implementing suggestions

dependent-type-member-pointer.cpp is failing on a win64 bot because
-fms-extensions is not enabled. Use ConvertType rather than relying on
the inheritance attributes. It's less code, but probably slower.
llvm-svn: 207819
The Win64 ABI docs on MSDN say that arguments bigger than 8 bytes are
passed by reference. Prior to this change, we were only applying this
logic to RecordType arguments. This affects both the Itanium and
Microsoft C++ ABIs.

This code is trying to test if the pointer is *not* null. Therefore we
should use 'or' instead of 'and' to combine the results of 'icmp ne'.
This logic is consistent with the general member pointer comparison code
in EmitMemberPointerComparison.

order by the number of missing or extra parameters. This is useful if
there are more than a few overload candidates with arity mismatches,
particularly in the presence of -fshow-overloads=best.

Enclosing the original #include directive inside #if 0 adds lines,
so warning/errors messages would have the line number off in
"In file included from <file>:<line>:", so add line marker to fix this.

Summary:
Previously, we would generate a single name for all reference
temporaries and allow LLVM to rename them for us. Instead, number the
reference temporaries as we build them in Sema.

We accept 'void *p; p->~void();' for MSVC compatibility since r148682.
However, we were returning ExprError, rather than producing an AST,
despite only diagnosing it with a warning. CodeGen noticed that the
template function specialization had an invalid AST, and therefore
didn't generate code for it. This change makes us produce an AST with a
void pseudo-dtor call.
Part of PR18256.

"1" means entering a new file (from a different one), but the main
file is not included from anything (and this would e.g. confuse -Wunused-macros
to not report unused macros in the main file, see pr15610, or also see pr18948).
The line marker is still useful e.g. if the resulting file is renamed or used
via a pipe.

There's nothing wrong with the change itself, but
test/Frontend/rewrite-includes-messages.c fails without another
not-yet-committed fix.

We need to open an ASTFile while checking its expected size and
modification time, or another clang instance can modify the file between
the stat() and the open().

We were destroying them in the callee, and then again in the caller. We
should use an EH-only cleanup and disable it at the point of the call
for win64, even though we don't use inalloca.

Since the community says that a blacklist is not good enough, and I don't have
enough time now to implement a proper whitelist, let's just remove the
attribute validation.
But, nevertheless, we can still communicate in the generated XML if our parser
found an issue with the HTML. But this bit is best-effort and is specifically
called out in the schema as such.

It moves them at the end of the range instead, so an extra erase is needed.
It is strange that this code works without the erase. On the other hand, removing the remove_if will make fail some tests.

We were emitting dynamic initializers for __thread variables if there
was no explicit initializer, as in this test case:
struct S { S(); };
__thread S s;

glibc expects that stddef.h only defines a single thing if either of these
defines is set. For example, before this change, a C file containing
#include <stdlib.h>
int ptrdiff_t = 0;
would compile with gcc but not with clang. Now it compiles with clang too.
This also fixes PR12997, where older versions of the Linux headers would define
NULL incorrectly, and glibc would define __need_NULL and expect stddef.h to
redefine NULL with the correct definition.

This fixes a bug where an update record causes us to load an entity that refers
to an entity we've not finished loading yet, resulting in badness.

After this patch clang will ignore -fdwarf2-cfi-asm and -ffno-dwarf2-cfi-asm and
always print assembly that uses cfi directives.
In llvm, MC itself supports cfi since the end of 2010 (support started
in r119972, is reported in the 2.9 release notes).
In binutils the support has been around for much longer. It looks like
support started to be added in May 2003. It is available in 2.15
(31-Aug-2011, 2.14 is from 12-Jun-2003).
llvm-svn: 207602
While we don't model pointer-to-member operators yet (neither .* nor ->*),
CallAndMessageChecker still checks to make sure the 'this' object is not
null or undefined first. However, it also expects that the object should
always have a valid MemRegion, something that's generally important elsewhere
in the analyzer as well. Ensure this is true ahead of time, just like we do
for member access.

Fixed by moving ProcessWarningOptions from Frontend into Basic. All of
the dependencies for ProcessWarningOptions were already in Basic, so
this was a small change.
