Reverting rev 112791 - apparently -fborland-extensions is on all the time?!

llvm-svn: 112797

Add support for Borland extensions via option -fborland-extensions

llvm-svn: 112791

Straighten out target triples provided on the command line
before using them.

llvm-svn: 112468

Frontend: Add basic -H support.
- I didn't implement the GCC "multiple include guard" detection parts, because
it doesn't seem useful or obvious.

llvm-svn: 111983

correct the -isystem option to not add the -isysroot path. Only the weird
-iwithsysroot flag should do that. This fixes rdar://8345942

llvm-svn: 111979

Implement -iwithsysroot, an apple extension which is a close cousin of -isystem.
Instead of implementing -isystem, I accidentally implemented this cousin. Next
up is to implement -isystem right.

Add machine-parseable Fix-It output as part of diagnostics, under the

Reintroduce the serialization library, with fixed dependencies.

Extend the code-completion caching infrastructure to include global
declarations (in addition to macros). Each kind of declaration maps to
a certain set of completion contexts, and the ASTUnit completion logic
introduces the completion strings for those declarations if the actual
code-completion occurs in one of the contexts where it matters.

There are a few new code-completion-context kinds. Without these,
certain completions (e.g., after "using namespace") would need to
suppress all global completions, which would be unfortunate.

Note that we don't get the priorities right for global completions,
because we don't have enough type information. We'll need a way to
compare types in an ASTContext-agnostic way before this can be
implemented.

will apply all fixes even when there were other errors in the file.

Just disable the hidden-visibility optimization for now by hiding it behind
a -cc1 option. The Darwin linker complains about mixed visibility when linking
gcc-built objects with clang-built objects, and the optimization isn't really
that valuable. Platforms with less ornery linkers can feel free to enable this.

Implement -fno-validate-pch at the -cc1 level, which suppresses most
of the usual consistency checks used to determine when a precompiled
header is incompatible with the translation unit it's being loaded
into.

Enable this option when loading a precompiled preamble, because the
preamble loader will be performing all of this checking itself. Enable
the preamble-based test now that it's working.

This option is also useful for debugging Clang's PCH
(<rdar://problem/7532213>).

Introduce basic support for loading a precompiled preamble while
reparsing an ASTUnit. When saving a preamble, create a buffer larger
than the actual file we're working with but fill everything from the
end of the preamble to the end of the file with spaces (so the lexer
will quickly skip them). When we load the file, create a buffer of the
same size, filling it with the file and then spaces. Then, instruct
the lexer to start lexing after the preamble, therefore continuing the
parse from the spot where the preamble left off.

It's now possible to perform a simple preamble build + parse (+
reparse) with ASTUnit. However, one has to disable a bunch of checking
in the PCH reader to do so. That part isn't committed; it will likely
be handled with some other kind of flag (e.g., -fno-validate-pch).

As part of this, fix some issues with null termination of the memory
buffers created for the preamble; we were trying to explicitly
NULL-terminate them, even though they were also getting implicitly
NULL terminated, leading to excess warnings about NULL characters in
source files.

worked for C anyway. Also kills the -cc1 options -parse-noop and
-parse-print-callbacks.

Introduce a new lexer function to compute the "preamble" of a file,
which is the part of the file that contains all of the initial
comments, includes, and preprocessor directives that occur before any
of the actual code. Added a new -print-preamble cc1 action that is
only used for testing.
