Added (incomplete) implementation of SimulEngine, a worklist-based dataflow
solver for path-sensitive, intra-procedural analysis.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45306 91177308-0d34-0410-b5e6-96231b3b80d8

Another test case, testing a variety of objective-c type comparisons.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45302 91177308-0d34-0410-b5e6-96231b3b80d8

Another test for objective-c's type comparison.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45301 91177308-0d34-0410-b5e6-96231b3b80d8

Converted Loc back to being of type ProgramEdge. Ultimately I believe we want
the ability to refer to the vertex set for all the vertices associated with an
edge. This will allow some nice queries over the graph, and (hopefully) will
reduce the memory footprint of SimulVertex.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45299 91177308-0d34-0410-b5e6-96231b3b80d8

Added preliminary implementation of SimulGraph, which represents the
intra-procedural supergraph of a path-sensitive dataflow analysis.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45298 91177308-0d34-0410-b5e6-96231b3b80d8

Changed "Location" from "ProgramEdge" to "ProgramEdge&" (slightly more svelt
memory representation).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45297 91177308-0d34-0410-b5e6-96231b3b80d8

SimulVertex now subclasses FoldingSetNode.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45296 91177308-0d34-0410-b5e6-96231b3b80d8

Added Profile method to SimulVertex.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45295 91177308-0d34-0410-b5e6-96231b3b80d8

This patch implements some of the more obscure type-checking involving
'id' quallified with protocols and static types which have categories and
inheritance which implement these protocols.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45294 91177308-0d34-0410-b5e6-96231b3b80d8

Updated Xcode project to be in sync with recent changes in file locations
introduced in r45292 (http://llvm.org/viewvc/llvm-project?rev=45292&view=rev)

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45293 91177308-0d34-0410-b5e6-96231b3b80d8

Directory restructing of Analysis files.

Created include/clang/Analysis/Analyses directory.
  - Moved LiveVariables.h and UninitializedValues.h into this dir.

Moved ExprDeclBitVector.h into Analysis/Support.

Updated all clients who use these headers to reflect the new paths.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45292 91177308-0d34-0410-b5e6-96231b3b80d8

Renamed file AnalysisVertex.h to SimulVertex.h

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45291 91177308-0d34-0410-b5e6-96231b3b80d8

Renamed class AnalysisVertex to SimulVertex

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45290 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed successor order for CFG basic blocks when handling: x && y.  The bug
is best explained by illustration:

[ B2 ]
     1: x
     T: [B2.1] && ...
   Predecessors (1): B4
   Successors (2): B3 B1

Block "B3" should be the block where we evaluate "y" when "x" evaluates to
true. Previously we had the successor list reversed. Now this behavior matches
with how we handle other conditional branches.

Thanks to Nuno Lopes for reporting this problem.

Patch to compare to objective-c static types where one or the other
(but not both) may be a protocol qualified static type.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45283 91177308-0d34-0410-b5e6-96231b3b80d8

More objective-c type analysis. This time involving objective types
of conforming protocols (or not).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45276 91177308-0d34-0410-b5e6-96231b3b80d8

Added class "StateVariant", a template class which serves to wrap states that
are generated by transfer functions used by the path-sensitive dataflow solver.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45273 91177308-0d34-0410-b5e6-96231b3b80d8

Added initial implementation of "AnalysisVertex", a class to represent a
location*state vertex in an intra-procedural, path-sensitive dataflow
supergraph.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45272 91177308-0d34-0410-b5e6-96231b3b80d8

Another test for objective-c type comparison.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45271 91177308-0d34-0410-b5e6-96231b3b80d8

More objective-c type checking. This time comparing objective-c known objects.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45269 91177308-0d34-0410-b5e6-96231b3b80d8

Converted uses of scoped_ptr to OwningPtr.

Patch to do type-checking for objctive-c's object types.
More is yet to come.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45263 91177308-0d34-0410-b5e6-96231b3b80d8

Fix trivial self-infinite-recursion

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45248 91177308-0d34-0410-b5e6-96231b3b80d8

More objective-c typechecking stuff. This is work in progress and more patches
are due to arrive.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45244 91177308-0d34-0410-b5e6-96231b3b80d8

Implement codegen for ordered comparison builtins.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45243 91177308-0d34-0410-b5e6-96231b3b80d8

Created initial implementation of "BuildSerializer", and ASTConsumer
which serializes ASTs to a common output directory.  This ASTConsumer
is invoked using a combination of "-o" and "-serialize" from the driver.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45241 91177308-0d34-0410-b5e6-96231b3b80d8

Renamed "FileEntry::getDev()" to "FileEntry::getDevice()"

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45240 91177308-0d34-0410-b5e6-96231b3b80d8

implement semantic analysis for __builtin_islessequal and friends.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45239 91177308-0d34-0410-b5e6-96231b3b80d8

Added method getFileEntryForID() to SourceManager.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45237 91177308-0d34-0410-b5e6-96231b3b80d8

simplify some code.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45235 91177308-0d34-0410-b5e6-96231b3b80d8

refactor some code that handles sema of direct function calls.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45234 91177308-0d34-0410-b5e6-96231b3b80d8

Add iterator interface to function/method parameters.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45233 91177308-0d34-0410-b5e6-96231b3b80d8

Split serialization ASTConsumers into two consumers: SingleFileSerializer and
BuildSerializer. The former serializes a single translation unit to a
corresponding .ast file. The second serializes ASTs to a common emission
direction.  The latter is not fully implemented yet.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45232 91177308-0d34-0410-b5e6-96231b3b80d8

Added methods createMainFileID() and createMainFileIDForMemBuffer() to
SourceManager to allow SourceManager to directly intern the MainFileID
when it is created.  Removed setMainFileID().

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45231 91177308-0d34-0410-b5e6-96231b3b80d8

Interned MainFileID within SourceManager. Since SourceManager is referenced by
both Preprocessor and ASTContext, we no longer need to explicitly pass
MainFileID around in function calls that also pass either Preprocessor or
ASTContext. This resulted in some nice cleanups in the ASTConsumers and the
driver.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45228 91177308-0d34-0410-b5e6-96231b3b80d8

Removed "SourceFile" from TranslationUnit. This same information will (soon)
be available by querying the SourceManager within the ASTContext referenced by
the TranslationUnit.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45223 91177308-0d34-0410-b5e6-96231b3b80d8

Added "-o" option to driver.  ASTConsumers will need to be gradually
rewired to utilize this option.

Renamed option --serialize-ast --serialize.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45213 91177308-0d34-0410-b5e6-96231b3b80d8

Add support for #pragma mark, which shouldn't warn about bogus tokens.

Removed storing inode and device number in TranslationUnit.

Added "SourceFile" string to TranslationUnit to record corresponding
source file.

Updated serialization of TranslationUnits and logic in the driver to
correctly pass the source file information to the serializer.

Fix the location we emit the "not a constant" error for this:

int foo() {
  typedef int x[foo()];
  static int y = sizeof(x);
}

previously we'd emit it on the typedef, which made not sense at all.

this method.

Add DefaultFunctionArrayConversion() to the indirection operator in Sema::ActOnUnaryOp().

This fixes a bug Chris forwarded from Oliver Hunt...

typedef struct { char name[100]; } entry;
char f1(entry *e) { return *e->name; }

Fixe bogus error for variable argument methods. Sema::ObjcGetTypeForMethodDefinition() wasn't preserving the isVariadic boolean. Another fix is to avoid synthsizing the function decl entirely, however this is a separate issue that I don't want to deal with now. Also added a FIXME to Sema::CheckFunctionCall(), which is currently emitting a bogus warning.

Turns out the LLVMFoldingBuilder can fold InsertElement. Knowing this, we can get rid of our special casing of constants when creating vectors.

Improve how we find private method decls. This involved:

- Changed Sema::ObjcActOnStartOfMethodDef() to register the methods with the global pools.
- Changed Sema::ActOnInstanceMessage() to look in global pools (should be much less error prone).
- Added a test case to message.m (for lookup that was broken).

Misc changes while I was investigating this...

- Changed Sema::ActOnAtEnd() to call AddFactoryMethodToGlobalPool (this looked like a cut/paste error).
- Added a comment and tweaked another where I was using the first person.

Add __private_extern__ keyword and recognize it. Added a FIXME to indicate there is still work to do.

left is this crazy thing called "testing".

implement enough helper functions to successfully dump out the
contents of the header map.  Look ma, no assumptions about input data
here (aka, corrupt header maps can't crash the compiler - crazy thought).

Modified format-string checking to not emit a warning when all of the
following hold:

(1) A vprintf-like function is called that takes the argument list via a
    via_list argument.

(2) The format string is a non-literal that is the parameter value of
    the enclosing function, e.g:

    void logmessage(const char *fmt,...) {
      va_list ap;
      va_start(ap,fmt);
      fprintf(fmt,ap);  // Do not emit a warning.
    }

In the future this special case will be enhanced to consult the "format"
attribute attached to a function declaration instead of just allowing a blank
check for all function parameters to be used as format strings to vprintf-like
functions. This will happen when more support for attributes becomes
available.

simplify some code, using new scoped_ptr support.  Fix a bug in the
cross-endianness case, where we checked the version in the wrong endianness.
Amusingly, the GCC logic that detects mixed endianness hmaps and rejects
them is dead for this very reason.
