Implement codegen support for:

Big fixme remains.

Generate code for target specific intrinsics.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44744 91177308-0d34-0410-b5e6-96231b3b80d8

The flags on tokens indicate whether they are the start of a *physical* line,
not the start of a logical line.  Be careful about this distinction, which
affects when newlines are printed and when paste-avoidance happens, etc.
This fixes PR1848, thanks to Neil for noticing this!

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44743 91177308-0d34-0410-b5e6-96231b3b80d8

Fix a pretty big but subtle bug counting the number of newlines to emit.
This would cause us to emit different code (in -E mode) for these two files:

---
#define t(x) x

t(a
3)
---
#define t(x) x
t(a
3)
---

In one case, -E would print "a\n3", in the other it printed "a3".  Now
it prints "a3" for both.

This is part of PR1848.

Add dumping support for locations, make -dumptokens print out the location
info of each token.

Add getTargetPrefix to TargetInfo, to be used with target specific intrinsics.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44712 91177308-0d34-0410-b5e6-96231b3b80d8

Test case for my last patch for implementation of static protocoled type
used as reciver type of a message expression.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44693 91177308-0d34-0410-b5e6-96231b3b80d8

Omit the field name when including the super class structure template.

This allows us to access a superclasses ivars without deriving the absolute path.

The comments below say a bit more...

Implemented when static typing is combined with protocols and use as receiver
type.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44685 91177308-0d34-0410-b5e6-96231b3b80d8

Have Sema::CheckConstantInitList skip semantic analysis when the element type is a record (until we implement the FIXME). This removes a bogus error for the following code...

snarofflocal% cat bug.m

#import <Foundation/NSGeometry.h>

#define NUMHELICOPTERRECTS 5

static NSRect helicopterRects[NUMHELICOPTERRECTS] = {
    {{27, 0}, {18, 11}}, // Bottom
    {{0, 8}, {4, 11}}, // Tail
    {{0, 16}, {50, 1}},
    {{22, 5}, {18, 12}}, // Body
    {{0, 10}, {42, 3}}
};

Lookup methods in the global pool even when a statically typed object's class interface isn't in scope!

As the comment in the code indicates, I'm not fond of this. Nevertheless, gcc compat is a goal.

Here is the case I'm talking about...

#import <Foundation/Foundation.h>

@interface AnyClass : NSObject
- (NSRect)rect;
@end

@class Helicopter;

static void func(Helicopter *obj) {
  NSRect r = [obj rect];
}

...before this patch, we would warn/error. With this patch, everything "just works".

Rewrite 'super' within a class method. This required some minor tweaks to the front-end.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44673 91177308-0d34-0410-b5e6-96231b3b80d8

On Steve's suggestion, moved handling of use of undeclared method in a message
to rewriter (my previous patch).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44665 91177308-0d34-0410-b5e6-96231b3b80d8

More struct bitfields layout work. Now handle,

A missing method in a messaging expression issues a warning, clients must not
crash because of this.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44648 91177308-0d34-0410-b5e6-96231b3b80d8

Subdivided the function InitializeBaseLanguage into InitializeBaseLanguage,
GetLanguage, and InitializeLangOptions.  The goal is to break up this logic
into atomic units of functionality that can later be refactored into better
driver logic that is capable of handling a mixture of source files of
different languages.

Removed dependence on including iostream (use llvm/Support/Streams.h instead).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44635 91177308-0d34-0410-b5e6-96231b3b80d8

XCode project.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44632 91177308-0d34-0410-b5e6-96231b3b80d8

Added "TranslationUnit" class that will be used to provide an interface
for serializing/deserializing ASTs that is decoupled from the logic
in SerializationTest (which will soon be rewritten to use this interface).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44631 91177308-0d34-0410-b5e6-96231b3b80d8

Modified: CreateTargetInfo().  Now takes Diagnostic* instead of Diagnostic&.
Modified: ctor of SerializationTest: Now takes LangOptions argument.  We
          will eventually serialize this as well.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44630 91177308-0d34-0410-b5e6-96231b3b80d8

Moved creation of ASTConsumers that can operate on both freshly-parsed and
deserialized ASTs into the function CreateASTConsumer().  This function
is called by ProcessInputFile, and soon the logic that processes deserialized
ASTs.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44618 91177308-0d34-0410-b5e6-96231b3b80d8

Revert DidWarn change - It won't catch all cases anyway and GCC warns for every excess element. Maybe later we can add back the limit and make it smarter.

Renamed SourceManager::Read to SourceManager::CreateAndRegister.
Now sourcemanager deserializer automatically self-registers itself with
the deserializer.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44591 91177308-0d34-0410-b5e6-96231b3b80d8

Removed serialization of FileEntry and DirectoryEntry.  This objects will
now be lazily recreated upon deserialization.

Type-cast initializers for "struct objc_super" parameter to avoid warning.

Don't assert if objc.h not declared when rewriting.

Implemented serialization of SrcMgr::ContentCache.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44578 91177308-0d34-0410-b5e6-96231b3b80d8

Removed a "TODO" comment as objc1 runtime does not need to do the "TODO".

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44577 91177308-0d34-0410-b5e6-96231b3b80d8

Simplified setting up Method's scope before generating AST for its nody.

Fixed a few more comments to change "FileInfo" to "ContentCache."

Removed searching for "darwin" keyword in target triple. We don't really support
any alternative targets at this point other than "darwin," so we now default to
Darwin targets (for now).

Removed IntrusiveSPtr.  There are no clients of this class anymore, so it is
not needed, and it was never extensively tested.  If we need an intrusive
reference-counting smart pointer, we can always import intrusive_ptr from
boost.

For target processing, on non-Darwin systems instead of using the host triple,
we default to "i386-apple-darwin".  This is an interim solution.

Removed processing of "linux" triples from Targets.cpp, since we don't have
any sensical Linux target support (yet).

Cleaned up error processing of targets; added better diagnostics.

Change <Objc/objc.h> to <objc/objc.h>

Implemented serialization of TargetInfo.
SerializationTest (subclass of ASTConsumer) now takes Diagnostics& in its ctor.

Few cleanups to patch 44551:

  http://llvm.org/viewvc/llvm-project?view=rev&revision=44551

Removed debugging fprintfs for printing targets.
Implemented error messages when processing invalid targets.
