ccc: Recognize that -M and -MM only run preprocessor.
 - Clean up some placement of output args to match gcc more precisely
   (for testing).

Remove ScopedDecl, collapsing all of its functionality into Decl, so
that every declaration lives inside a DeclContext.

Moved several things that don't have names but were ScopedDecls (and,
therefore, NamedDecls) to inherit from Decl rather than NamedDecl,
including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't
store empty DeclarationNames for these things, nor do we try to insert
them into DeclContext's lookup structure.

The serialization tests are temporarily disabled. We'll re-enable them
once we've sorted out the remaining ownership/serialiazation issues
between DeclContexts and TranslationUnion, DeclGroups, etc.

Dead stores checker: Fix <rdar://problem/6506065> by being more selective when say that a store is dead even though the computed value is used in the enclosing expression.

ccc: Darwin/x86: Add direct cpp support.
 - Add Darwin_X86_CC1Tool which is shared by Darwin/x86/Compile and
   Darwin/x86/Preprocess tools.

 - Minor bug fixes (CmpDriver exit code, -x cpp-output handling, some

PTH: Emitted tokens now consist of 12 bytes that are loaded used 3 32-bit loads.  This reduces user time but increases system time because of the slightly larger PTH file.  Although there is no performance win on Cocoa.h and -Eonly, overall this seems like a good step.

Centralize error reporting of improper uses of incomplete types in the
new DiagnoseIncompleteType. It provides additional information about
struct/class/union/enum types when possible, either by pointing to the
forward declaration of that type or by pointing to the definition (if

ccc: Add installation of ccc; based on patch from Mike Stump.
 - This doesn't follow normal installation procedure of python
   code, but no sense trying too hard since ccc will be moved to

Switch MinimalAction from new/delete'ing its TypeNameInfo to

Avoid malloc thrashing on the std::vector for ConditionalStack.  Because

On i386 and x86-64, just do unaligned loads

switch PTH lexer from using "const char*"s to "const unsigned char*"s

Rename SourceLocation::getFileID to getChunkID, because it returns
the chunk ID not the file ID.  This exposes problems in

Change the Lexer ctor used to lex _Pragma directives into a static factory
method.  This lets us clean up the interface and make it more obvious that
this method is *really really* _Pragma specific.

Note that _Pragma handling uglifies the Lexer in the critical path.  It would
be very interesting to consider making _Pragma remapping be a new special
lexer class of its own.

Change the Lexer ctor used in the non _Pragma case to take a FileID instead

make the verbose raw-lexer ctor fully explicit instead of having
embedded magic.

add a simplified lexer ctor that sets up the lexer to raw-lex an
entire file.

Update checker build.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62409 91177308-0d34-0410-b5e6-96231b3b80d8

suck the call to "getSpellingLoc" that all clients do into
the implementation of PTHManager::getSpelling.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62408 91177308-0d34-0410-b5e6-96231b3b80d8

this massive patch introduces a simple new abstraction: it makes
"FileID" a concept that is now enforced by the compiler's type checker
instead of yet-another-random-unsigned floating around.

This is an important distinction from the "FileID" currently tracked by
SourceLocation.  *That* FileID may refer to the start of a file or to a
chunk within it.  The new FileID *only* refers to the file (and its
#include stack and eventually #line data), it cannot refer to a chunk.

FileID is a completely opaque datatype to all clients, only SourceManager
is allowed to poke and prod it.

make "ContentCache::Buffer" mutable to avoid a const_cast.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62403 91177308-0d34-0410-b5e6-96231b3b80d8

no need to check this: content cache is already 1-1 map with fileentries.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62402 91177308-0d34-0410-b5e6-96231b3b80d8

Instead of iterating over FileID's, have PTH generation iterate over the
content cache directly.  Content cache has a 1-1 mapping with fileentries,
whereas multiple FileIDs can be the same FileEntry.

Fix analyzer crash found when scanning Wine sources where the analyzer used old logic to determine the value of a switch 'case' label.

ccc: Don't be pedantically compatible with -Z options, these are the
result of an internal implementation detail of gcc.

add support for usage of cast to union thing with static vars

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62387 91177308-0d34-0410-b5e6-96231b3b80d8

Teach DeclContext how to find the primary declaration for any TagDecl
even when we are still defining the TagDecl. This is required so that
qualified name lookup of a class name within its definition works (see
the new bits in test/SemaCXX/qualified-id-lookup.cpp).

As part of this, move the nested redefinition checking code into
ActOnTag. This gives us diagnostics earlier (when we try to perform
the nested redefinition, rather than when we try to complete the 2nd
definition) and removes some code duplication.

Convert some more statement actions to smart pointers.
Fix a type error; parser wanted to pass the third part of a for-statement as a statement; should be expression.

ccc: Clean up (user level) error handling.
 - ccc now checks for existence of input files (more annoying to test,

 - Fix some test cases.
