Steve Naroff b59212a6e4 CodeGenModule::GetAddrOfConstantCFString():
- Finish up support for converting UTF8->UTF16 to support ObjC @"string" constants.

Remove warning from CheckObjCString.

As the FIXME in the test case indicates, I still have a bug to work out (apparently with \u handling).

Steve Naroff e9b7d8ace8 Add ConvertUTF module from http://www.unicode.org/Public/PROGRAMS/CVTUTF.
#ifdef'd out the 5 conversion routines that we don't currently need.

Still need a bit more work in GetAddrOfConstantCFString(). Added a FIXME to indicate this.

Expect to remove the FIXME today...

Daniel Dunbar 8e5c2b8072 Add Target hooks for IRgen of [cf]string literals.

Chris Lattner ca3f25c1fb fix several problems with asm renaming, by pulling it into the mangling code:
1. it wasn't applying to definitions, only declarations, e.g. int x __asm("foo")
2. multiple definitions were conflicting, they weren't getting merged.
3. the code was duplicated in several places.

Douglas Gregor 3e41d60eb6 Implicitly declare certain C library functions (malloc, strcpy, memmove,
etc.) when we perform name lookup on them. This ensures that we
produce the correct signature for these functions, which has two
practical impacts:

  1) When we're supporting the "implicit function declaration" feature
  of C99, these functions will be implicitly declared with the right
  signature rather than as a function returning "int" with no
  prototype. See PR3541 for the reason why this is important (hint:
  GCC always predeclares these functions).
 
  2) If users attempt to redeclare one of these library functions with
  an incompatible signature, we produce a hard error.

This patch does a little bit of work to give reasonable error
messages. For example, when we hit case #1 we complain that we're
implicitly declaring this function with a specific signature, and then
we give a note that asks the user to include the appropriate header
(e.g., "please include <stdlib.h> or explicitly declare 'malloc'"). In
case #2, we show the type of the implicit builtin that was incorrectly
declared, so the user can see the problem. We could do better here:
for example, when displaying this latter error message we say
something like:

  'strcpy' was implicitly declared here with type 'char *(char *, char
  const *)'

but we should really print out a fake code line showing the
declaration, like this:

  'strcpy' was implicitly declared here as:

    char *strcpy(char *, char const *)

This would also be good for printing built-in candidates with C++
operator overloading.

The set of C library functions supported by this patch includes all
functions from the C99 specification's <stdlib.h> and <string.h> that
(a) are predefined by GCC and (b) have signatures that could cause
codegen issues if they are treated as functions with no prototype
returning and int. Future work could extend this set of functions to
other C library functions that we know about.

Douglas Gregor 5f2bfd4811 Add basic support for C++ name mangling according to the Itanium C++
ABI to the CodeGen library. Since C++ code-generation is so
incomplete, we can't exercise much of this mangling code. However, a
few smoke tests show that it's doing the same thing as GCC. When C++
codegen matures, we'll extend the ABI tester to verify name-mangling
as well, and complete the implementation here.

At this point, the major client of name mangling is in the uses of the
new "overloadable" attribute in C, which allows overloading. Any
"overloadable" function in C (or in an extern "C" block in C++) will
be mangled the same way that the corresponding C++ function would be
mangled.

Douglas Gregor 44b4321fea Unifies the name-lookup mechanisms used in various parts of the AST
and separates lexical name lookup from qualified name lookup. In
particular:
  * Make DeclContext the central data structure for storing and
    looking up declarations within existing declarations, e.g., members
    of structs/unions/classes, enumerators in C++0x enums, members of
    C++ namespaces, and (later) members of Objective-C
    interfaces/implementations. DeclContext uses a lazily-constructed
    data structure optimized for fast lookup (array for small contexts,
    hash table for larger contexts). 

  * Implement C++ qualified name lookup in terms of lookup into
    DeclContext.

  * Implement C++ unqualified name lookup in terms of
    qualified+unqualified name lookup (since unqualified lookup is not
    purely lexical in C++!)

  * Limit the use of the chains of declarations stored in
    IdentifierInfo to those names declared lexically.

  * Eliminate CXXFieldDecl, collapsing its behavior into
    FieldDecl. (FieldDecl is now a ScopedDecl).

  * Make RecordDecl into a DeclContext and eliminates its
    Members/NumMembers fields (since one can just iterate through the
    DeclContext to get the fields).

2008-11-19 06:15:35 +00:00
Chris Lattner 0a14eee528 This reworks some of the Diagnostic interfaces a bit to change how diagnostics
are formed.  In particular, a diagnostic with all its strings and ranges is now
packaged up and sent to DiagnosticClients as a DiagnosticInfo instead of as a 
ton of random stuff.  This has the benefit of simplifying the interface, making
it more extensible, and allowing us to do more checking for things like access
past the end of the various arrays passed in.

In addition to introducing DiagnosticInfo, this also substantially changes how 
Diagnostic::Report works.  Instead of being passed in all of the info required
to issue a diagnostic, Report now takes only the required info (a location and 
ID) and returns a fresh DiagnosticInfo *by value*.  The caller is then free to
stuff strings and ranges into the DiagnosticInfo with the << operator.  When
the dtor runs on the DiagnosticInfo object (which should happen at the end of
the statement), the diagnostic is actually emitted with all of the accumulated
information.  This is a somewhat tricky dance, but it means that the 
accumulated DiagnosticInfo is allowed to keep pointers to other expression 
temporaries without those pointers getting invalidated.

This is just the minimal change to get this stuff working, but this will allow
us to eliminate the zillions of variant "Diag" methods scattered throughout
(e.g.) sema.  For example, instead of calling:

  Diag(BuiltinLoc, diag::err_overload_no_match, typeNames,
       SourceRange(BuiltinLoc, RParenLoc));

We will soon be able to just do:

  Diag(BuiltinLoc, diag::err_overload_no_match)
      << typeNames << SourceRange(BuiltinLoc, RParenLoc));

This scales better to support arbitrary types being passed in (not just 
strings) in a type-safe way.  Go operator overloading?!

Daniel Dunbar f1968f2886 Add simple interface for protecting runtime functions from name
collisions.
 - Provide CodeGenModule::CreateRuntimeFunction which guarantees that
   the function it creates will have the provided name in the final
   module. This allows the runtime to have its functions protected
   from declarations of the same name in the source code.

 - One could argue that this is a reason to abuse the llvm::Module
   namespace for dealing with function redeclarations. However, that
   approach seems conceptually flawed to me. This one also happens to
   be somewhat more efficient.

No functionality change.

Devang Patel a2c6912c41 Now Attributes are divided in three groups

- function attributes - nounwind, readonly, readnone, noreturn

Return attributes use 0 as the index.
Function attributes use ~0U as the index.

Ted Kremenek 815c78fd9a Refactored driver logic for CodeGen into LLVMCodeGenWriter. This ASTConsumer layers on top of LLVMCodeGen (another existing ASTConsumer) to emit bitcode files to disk.

Chris Lattner c63a1f276f Finally fix PR2189. This makes a fairly invasive but important change to
move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).

Fixing this greatly simplifies getArrayDecayedType, which is a good sign.

- No (intended) functionality change.

 - Primary purpose is to clearly separate (lazy) construction of

   those that are the final definition.

 - Lazy construction is now encapsulated in
   GetAddrOf{Function,GlobalVar} while final definitions are
   constructed in EmitGlobal{Function,Var}Definition.
 
 - External interface for dealing with globals is now limited to
   EmitGlobal and GetAddrOf{Function,GlobalVar}.

 - Also updated helper functions dealing with statics, annotations,
   and ctors to be private.

Eli Friedman ff4a2d9e2c First cut at setting attributes for functions and calls; this puts us
much closer to passing the gcc struct layout tests.

It might be possible to refactor this a bit, but I'm not sure there's 
actually enough common code for that to be useful.

To get the calling convention completely correct, a bit of 
platform-specific code is necessary even for x86-Linux. On x86-Linux, the
alignment of function parameters is extremely strange; as far as I can tell,
it's always 4 except for SSE vectors or structs containing SSE vectors.  I'm 
continuing to investigate this.

Eli Friedman 77ba708819 Allow the type of a global to be different from the type of its
associated declaration. This is a prerequisite to handling
general union initializations; for example, an array of unions involving 
pointers has to be turned into a struct because the elements can have 
incompatible types.

I refactored the code a bit to make it more readable; now, the logic for 
definitions is all in EmitGlobalVarInit.

The second parameter for GetAddrOfGlobalVar is now dead; I'll remove it 
separately.

By itself, this patch should not cause any visible changes.

Eli Friedman 0c99509927 Emit memmove, not memcpy, for structure copies; this is unfortunately
required for correctness in cases of copying a struct to itself or to 
an overlapping struct (itself for cases like *a = *a, and overlapping 
is possible with unions).

Hopefully, this won't end up being a perf issue; LLVM *should* be able 
to optimize memmove to memcpy in a lot of cases, and for small copies 
the generated code *should* be mostly comparable. (In reality, LLVM 
is currently horrible at optimizing memmove, but that's a bug, not a 
fundamental issue.)

gcc currently generates wrong code; that's

Chris Lattner ce5605ecf7 some cleanups on top of David's patch. There are still two
remaining open issues I've communicated to him:

1) self can be assigned to, and his patch didn't handle it correctly.
2) CollectObjCIvarTypes is N^2 (because each subclass reprocesses
   all parent class ivars) and flattens classes.  If A derives from B, 
   and both have an int, I'd expect to get { {i32}, i32}, not { i32, i32}.

David, please review.

Chris Lattner bda0b626e7 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.
