buffer generated for the current translation unit. If they are
different, complain and then ignore the PCH file. This effectively
checks for all compilation options that somehow would affect
preprocessor state (-D, -U, -include, the dreaded -imacros, etc.).
When we do accept the PCH file, throw away the contents of the
predefines buffer rather than parsing them, since all of the results
of that parsing are already stored in the PCH file. This eliminates
the ugliness with the redefinition of __builtin_va_list, among other
things.

with identifiers. The basic example in the testcase works though.

into clang-cc.cpp. This makes it so clang-cc constructs the *entire* predefines
buffer, not just half of it. A bonus of this is that we get to kill a copy
of DefineBuiltinMacro.

improvement, source locations read from the PCH file will properly
resolve to the source files that were used to build the PCH file
itself.
Once we have the preprocessor state stored in the PCH file, source
locations that refer to macro instantiations that occur in the PCH
file should have the appropriate instantiation information.

de-serialization of abstract syntax trees.
PCH support serializes the contents of the abstract syntax tree (AST)
to a bitstream. When the PCH file is read, declarations are serialized
as-needed. For example, a declaration of a variable "x" will be
deserialized only when its VarDecl can be found by a client, e.g.,
based on name lookup for "x" or traversing the entire contents of the
owner of "x".
This commit provides the framework for serialization and (lazy)
deserialization, along with support for variable and typedef
declarations (along with several kinds of types). More
declarations/types, along with important auxiliary structures (source
manager, preprocessor, etc.), will follow.

- Add -static-define option driver can use when __STATIC__ should be
defined (instead of __DYNAMIC__).
- Don't set __OPTIMIZE_SIZE__ on Os, __OPTIMIZE_SIZE__ is tied to Oz.
- Set __NO_INLINE__ following GCC 4.2.
- Set __GNU_GNU_INLINE__ or __GNU_STDC_INLINE__ following GCC 4.2.
- Set __EXCEPTIONS for Objective-C NonFragile ABI.
- Set __STRICT_ANSI__ for standard conforming modes.
- I added a clang style test case in utils for this, but its not
particularly portable and I don't think it belongs in the test
suite.

- This is pretty ugly, but the most obvious solution. Chime in if you
have a nicer one.
- The problem is that with -save-temps, clang-cc has no idea what the
name of the original input file is. However, the user expects to be
able to set breakpoints based on the input file name.
- We support this by providing a new option -main-file-name (similar
to -dumpbase used by gcc) which allows the driver to pass in the
original file name.
- <rdar://problem/6753383> building with clang using --save-temps
gets the compile unit name from the .i file...

probably.
- For now, the clang-cc interface stays relatively the same, but we
don't accept multiple instances anymore, or the [no-] variants
directly.

break anything.

- <rdar://problem/6741594> [pth] don't abuse -x to drive pth
generation
- Simpler, and fixes PR3915.
Cleanup test cases for PTH:
- Update to use -emit-pth
- Removed PTH test of carbon.c and cocoa.mm; these didn't actually
verify anything, and since PTH is token based the extra coverage
(over cocoa.m) isn't particularly helpful.
- Split PTH tests in cocoa.m to cocoa-pth.m, solely to increase
available parallelism when running tests.
Ted, could you update the PTH test cases (include-pth.c and
cocoa-pth.m) to have some sort of positive check that the PTH is
getting used? "# of PTH cache hits" or "tokens read from PTH cache"
statistics would work great. :)
