modifying directly for the preamble.
This avoids an awful, hard to find, bug where "PreprocessorOpts.DisablePCHValidation = true"
would be persistent for subsequent reparses of the translation unit which would result
in defines, present in command-line but not in the PCH, being ignored.

IR gen needed to find the declarations of those symbols in the translation
unit.

function. This is really the beginning of the second phase of
refactorings here. The end goal is to have (roughly) three interfaces:
1) Base class to format a single diagnostic suitable for display on the
console.
2) Extension of the base class which also displays a caret diagnostic
suitable for display on the console.
3) An adaptor that implements the DiagnosticClient by delegating to #1
and/or #2 as appropriate.
Once we have these, things like libclang's formatDiagnostic can use #1
and #2 to provide really well formatted (and consistently formatted!)
textual formatting of diagnostics.
Getting there is going to be quite a bit of shuffling. I'm basically
sketching out where the interface boundaries can be drawn for #1 and #2
within the existing classes. That lets me shuffle with a minimum of fuss
and delta. Once that's done, and any of the related interfaces that need
to change are updated, I'll hoist these into separate headers and
re-implement libclang in terms of their interfaces. Long WIP, but
comments at each step welcome. =D

a stack array of a magical size with an assert() that we never
overflowed it. That seems incredibly risky. We also have a very nice API
for bundling up a vector we expect to usually have a small size without
loss of functionality or security if the size is excessive.
The fallout is to remove the last pointer+size parameter pair that are
traced through the recursive caret diagnostic emission.

a defined interface. This isn't as nice as the previous one, but should
get better as I push through better data types in all these functions.
Also, I'm hoping to pull some aspects of this out into a common routine
(such as tab expansion).
Again, WIP, comments welcome as I'm going through.

The function was only counting lines that included tokens and not empty lines,
but MaxLines (mainly initiated to the line where the code-completion point resides)
is a count of overall lines (even empty ones).

Preprocessor, eliminating the constructor that was used by ASTUnit
(which didn't provide an ASTContext or Prepreprocessor). Ensuring that
both objects are non-NULL will simplify module loading (but none of
that is done yet).
llvm-svn: 138986
builtin types (When requested). This is another step toward making
ASTUnit build the ASTContext as needed when loading an AST file,
rather than doing so after the fact. No actual functionality change (yet).

and language-specific initialization. Use this to allow ASTUnit to
create a preprocessor object *before* loading the AST file. No actual
functionality change.
llvm-svn: 138983
LangOptions, rather than making distinct copies of
LangOptions. Granted, LangOptions doesn't actually get modified, but
this will eventually make it easier to construct ASTContext and
Preprocessor before we know all of the LangOptions.

include guards don't show up as macro definitions in every translation
unit that imports a module. Macro definitions can, however, be
exported with the intentionally-ugly #__export_macro__
directive. Implement this feature by not even bothering to serialize
non-exported macros to a module, because clients of that module need
not (should not) know that these macros even exist.

(unsurprisingly) caret diagnostics. This is designed to bring some
organization to the monstrous EmitCaretDiagnostic function, and allow
factoring it more easily and with less mindless parameter passing.
Currently this just lifts the existing function into a method, and
splits off the obviously invariant arguments to be class members. No
functionality is changed, and there are still lots of warts to let
existing code continue functioning as-is. Definitely WIP, more cleanups
to follow.

loads the named module. The syntax itself is intentionally hideous and
will be replaced at some later point with something more
palatable. For now, we're focusing on the semantics:
- Module imports are handled first by the preprocessor (to get macro
definitions) and then the same tokens are also handled by the parser
(to get declarations). If both happen (as in normal compilation),
the second one is redundant, because we currently have no way to
hide macros or declarations when loading a module. Chris gets credit
for this mad-but-workable scheme.
- The Preprocessor now holds on to a reference to a module loader,
which is responsible for loading named modules. CompilerInstance is
the only important module loader: it now knows how to create and
wire up an AST reader on demand to actually perform the module load.
- We search for modules in the include path, using the module name
with the suffix ".pcm" (precompiled module) for the file name. This
is a temporary hack; we hope to improve the situation in the
future.

from the given source. -emit-module behaves similarly to -emit-pch,
except that Sema is somewhat more strict about the contents of
-emit-module. In the future, there are likely to be more interesting
differences.

Currently this includes -pedantic warnings as well; we'll need to consider whether these should
be included.
This works as expected with -Werror.
Test cases were added to Sema/warn-unused-parameters.c, but they should probably be broken off into
their own test file.

all AST files have a normal METADATA record that has the same form
regardless of whether we refer to a chained PCH or any other kind of
AST file.
Introduce the IMPORTS record, which describes all of the AST files
that are imported by this AST file, and how (as a module, a PCH file,
etc.). Currently, we emit at most one entry to this record, to support
chained PCH.

are fine because they could be the start of a category. Fixes

For PCH files, have only one open/close for temporary + rename to be safe from race conditions.
For all other output files open/close the output file directly.
