Sanjiv Gupta c1b58d40e6 Targets that don't have stack use global address space for parameters.
Specify external linkage for such globals so that llvm optimizer do
not assume there values initialized as zero.

Eli Friedman 7139af42ce Rename Expr::isConstantExpr to Expr::isConstantInitializer; this more
accurately states what the function is trying to do and how it is 
different from Expr::isEvaluatable.  Also get rid of a parameter that is both 
unused and inaccurate.

"logical" location, refer to the "instantiation" location.

Eli Friedman f4084708cd Make VLAs usable, and make basic usage work correctly. Also, add a
simple test that actually does VLA codegen.

Note that despite the fact that the alloca isn't in the entry block, it 
should dominate all uses; this is guaranteed by the restrictions on goto 
into VLA scope in C99.

Anders Carlsson 8a01b79274 Change EmitVLASize to take a QualType that must be a variably modified type.
Emit the size even if the declared type is a variably modified type. This lets us handle

void f(int n) {
  int (*a)[n];
  
  printf("size: %d\n", sizeof(*a));
}

Chris Lattner 1cbaacc4a0 Migrate some stuff from NamedDecl::getName() to
NamedDecl::getNameAsString() to make it more explicit.

Chris Lattner 86d7d91366 Rename NamedDecl::getIdentifierName() to ::getNameAsCString() and make it
assert if the name is not an identifier.  Update callers to do the right
thing and avoid this method in unsafe cases.  This also fixes an objc
warning that was missing a space, and migrates a couple more to taking
IdentifierInfo and QualTypes instead of std::strings.

Douglas Gregor 77324f3854 Introduction the DeclarationName class, as a single, general method of
representing the names of declarations in the C family of
languages. DeclarationName is used in NamedDecl to store the name of
the declaration (naturally), and ObjCMethodDecl is now a NamedDecl.

Chris Lattner affb37337f reimplement debug info generation in terms of DebugInfo.h instead of
using MachineModuleInfo.  This runs at about the same speed as the old
code, but fixes a bunch of bugs and is simpler and shorter.

Sanjiv Gupta d79592448b Made the mechanism of defining preprocessor defs for maxint, ptrdiff_t, wchar
etc more generic. For some targets, long may not be equal to pointer size. For
example: PIC16 has int as i16, ptr as i16 but long as i32.

Also fixed a few build warnings in assert() functions in CFRefCount.cpp,
CGDecl.cpp, SemaDeclCXX.cpp and ParseDeclCXX.cpp.

Daniel Dunbar b9fd902fdc Change CGDebugInfo::setLocation to just ignore invalid locations. This
simplifies clients.

Also, add assert that RegionStack is empty when the CGDebugInfo is
destroyed.

Argyrios Kyrtzidis 88e1b97f16 Simplify handling of struct/union/class tags.
Instead of using two sets of Decl kinds (Struct/Union/Class and CXXStruct/CXXUnion/CXXClass), use one 'Record' and one 'CXXRecord' Decl kind and make tag kind a property of TagDecl.
Cleans up the code a bit and better reflects that Decl class structure.

Daniel Dunbar a94ecd2a0b Add NeXT runtime support for generating methods.
Change CodeGenFunction::EmitParmDecl to take either a ParmVarDecl or an
  ImplicitParamDecl.

Drop hasAggregateLLVMType from CodeGenModule.cpp (use version in
  CodeGenFunction).

Change the Objective-C method generation to use EmitParmDecl for
  implicit parameters.

Eli Friedman 327944b343 Basic support for volatile loads and stores. Stores the volatile
qualifier in the lvalue, and changes lvalue loads/stores to honor 
the volatile flag.  Places which need some further attention are marked 
with FIXMEs.

Eli Friedman c98a7add43 Don't crash emitting an initializer for a static local with union type.
This fix just makes sure to construct the global with the appropriate 
type, and fixes up the one user this affects to compensate.

Dan Gohman 5d30975e5e Change uses of llvm::Type::isFirstClassType to use the new
llvm::Type::isSingleValueType. Currently these two functions have
the same behavior, but soon isFirstClassType will return true for
struct and array types.

Clang may some day want to use of isFirstClassType for some of
these some day as an optimization, but it'll require some
consideration.

Chris Lattner b781dc79aa Add basic support for the pic-* target triples and add support for
targets that do not support recursion (and thus codegen stack variables
as globals).

Steve Naroff 08899ff85d Remove FileVarDecl and BlockVarDecl. They are replaced by VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl().
This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

generator needs to call isAnyComplexType().  This fixes PR1960.

Chris Lattner 7a51313d8a Make a major restructuring of the clang tree: introduce a top-level
lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.
