John McCall 2e6567ae60 Call PerformCopyInitialization to properly initialize the exception temporary
in a throw expression.  Use EmitAnyExprToMem to emit the throw expression,
which magically elides the final copy-constructor call (which raises a new
strict-compliance bug, but baby steps).  Give __cxa_throw a destructor pointer
if the exception type has a non-trivial destructor.

John McCall bf814c79b6 I failed to notice that my last patch wasn't doing as much as it could
because EmitBranch actually clears the insert point.  This version

Anders Carlsson 6a0227df49 Fix a bug which triggered the assertion I added yesterday. Basically, when we initialize the vtable pointer for a virtual base, and there was another path from the most derived class to another base with the same class type, we would use the wrong base.

Anders Carlsson 74eab715ae More improvements to setting the vtable pointer. We now no longer set the vtable pointer for non-virtual primary bases. We also do a pre-order traversal of the class hierarchy; this is necessary in order to get the right vbase offset offsets in base ctors/dtors.

Blaine Garst fc83aa04db Unconditionally support block introspection data in a new field at the end
of the block descriptor field.  This field is the ObjC style @encode
signature of the implementation function, and was to this point
conditionally provided in the block literal data structure.  That
provisional support is removed.

Additionally, eliminate unused enumerations for the block literal flags field.
The first shipping ABI unconditionally set (1<<29) but this bit is unused
by the runtime, so the second ABI will unconditionally have (1<<30) set so
that the runtime can in fact distinguish whether the additional data is
present or not.

John McCall f8ff7b9fd1 Perform two more constructor/destructor code-size optimizations:
1) emit base destructors as aliases to their unique base class destructors
under some careful conditions.  This is enabled for the same targets that can
support complete-to-base aliases, i.e. not darwin.

2) Emit non-variadic complete constructors for classes with no virtual bases
as calls to the base constructor.  This is enabled on all targets and in
theory can trigger in situations that the alias optimization can't (mostly
involving virtual bases, mostly not yet supported).

These are bundled together because I didn't think it worthwhile to split them,
not because they really need to be.

2010-02-23 00:48:20 +00:00
John McCall b81884d347 More refactoring around constructor/destructor code generation.
Fix some bugs with function-try-blocks and simplify normal try-block
code generation.

This implementation excludes a deleting destructor's call to
operator delete() from the function-try-block, which I believe
is correct but which I can't find straightforward support for at
a moment's glance.

John McCall 347132b32f IRgen optimization: cache the value of 'this' and 'vtt' instead of
repeatedly reloading from an alloca.  We still need to create the alloca
for debug info purposes (although we currently create it in all cases
because of some abstraction boundaries that're hard to break down).

Daniel Dunbar d004918ccb IRgen: Add CreateIRTemp, which creates a temporary alloca but with type converted "not-for-memory". Dunno a better name.
llvm-svn: 96374
2010-02-16 19:44:13 +00:00
John McCall 6ce747220a When emitting complete destructors for classes with virtual bases, compute
the offset to the virtual bases statically inside of relying on the virtual
base offsets in the object's vtable(s).  This is both more efficient and
sound against the destructor's manipulation of the vtables.

Also extract a few helper routines.

Oh and we seem to pass all tests with an optimized clang now.

2010-02-16 04:15:37 +00:00
Daniel Dunbar a7566f163a IRgen: Add CreateMemTemp, for creating an temporary memory object for a particular type, and flood fill. - CreateMemTemp sets the alignment on the alloca correctly, which fixes a great many places in IRgen where we were doing the wrong thing.
- This fixes many many more places than the test case, but my feeling is we need to audit alignment systematically so I'm not inclined to try hard to test the individual fixes in this patch. If this bothers you, patches welcome!

Douglas Gregor 7bab5ff8e7 Eliminate CXXConditionDeclExpr with extreme prejudice.
All statements that involve conditions can now hold on to a separate
condition declaration (a VarDecl), and will use a DeclRefExpr
referring to that VarDecl for the condition expression. ForStmts now
have such a VarDecl (I'd missed those in previous commits).

Also, since this change reworks the Action interface for
if/while/switch/for, use FullExprArg for the full expressions in those
expressions, to ensure that we're emitting

Note that we are (still) not generating the right cleanups for

Douglas Gregor 680f861d74 Clean up the AST for while loops and fix several problems with
cleanups for while loops: 

1) Make sure that we destroy the condition variable of a while statement each time through the loop for, e.g.,

   while (shared_ptr<WorkInt> p = getWorkItem()) {
         // ...
         }

2) Make sure that we always enter a new cleanup scope for the body of the while loop, even when there is no compound expression, e.g.,

   while (blah)
     RAIIObject raii(blah+1);

2009-11-24 18:43:52 +00:00
Douglas Gregor 965f450d42 Introduce cleanup scopes for "if" statements in two places:
- Outside the "if", to ensure that we destroy the condition variable
    at the end of the "if" statement rather than at the end of the
    block containing the "if" statement.
  - Inside the "then" and "else" branches, so that we emit then- or
    else-local cleanups at the end of the corresponding block when the
    block is not a compound statement.

To make adding these new cleanup scopes easier (and since
switch/do/while will all need the same treatment), added the
CleanupScope RAII object to introduce a new cleanup scope and make
sure it gets cleaned up.

Douglas Gregor 4bd90e53c2 Eliminate QualifiedDeclRefExpr, which captured the notion of a
qualified reference to a declaration that is not a non-static data
member or non-static member function, e.g., 

  namespace N { int i; }
  int j = N::i;

Instead, extend DeclRefExpr to optionally store the qualifier. Most
clients won't see or care about the difference (since
QualifierDeclRefExpr inherited DeclRefExpr). However, this reduces the
number of top-level expression types that clients need to cope with,
brings the implementation of DeclRefExpr into line with MemberExpr,
and simplifies and unifies our handling of declaration references.

Extended DeclRefExpr to (optionally) store explicitly-specified
template arguments. This occurs when naming a declaration via a
template-id (which will be stored in a TemplateIdRefExpr) that,
following template argument deduction and (possibly) overload
resolution, is replaced with a DeclRefExpr that refers to a template
specialization but maintains the template arguments as written.

Chris Lattner 2bb5cb490c reimplement codegen for indirect goto with the following advantages:
1. CGF now has fewer bytes of state (one pointer instead of a vector).
2. The generated code is determinstic, instead of getting labels in
   'map order' based on pointer addresses.
3. Clang now emits one 'indirect goto switch' for each function, instead
   of one for each indirect goto.  This fixes an M*N = N^2 IR size issue
   when there are lots of address-taken labels and lots of indirect gotos.
4. This also makes the default cause do something useful, reducing the
   size of the jump table needed (by one).

Eli Friedman 04fddf0d1f Fix for PR4721: adjust CodeGen and ASTContext so that we have a
consistent model for handling size expressions for VLAs.

The model is essentially as follows: VLA types own their associated
expression.  In some cases, we need to create multiple VLA types to 
represent a given VLA (for canonical types, or qualifiers on array types,
or type merging).  If we need to create multiple types based off of 
the same VLA declaration, we use the new refcounting functionality so they can 
all own the expression. The VLASizeMap in CodeGenFunction then uses the size
expression to identify the group of VLA types based off of the same original
declaration.

I'm not particularly attached to the VLA types owning the expression, 
but we're stuck with at least until someone comes up with a way 
to walk the VLA expressions for a declaration.

I did the parallel fix in ASTContext for DependentSizedArrayType, but I 
haven't really looked closely at it, so there might still be issues 
there.

I'll clean up the code duplication in ASTContext in a followup commit.

2009-04-25 19:35:26 +00:00
Chris Lattner 28ec0cf86c the logic for computing __func__ and friends is really broken:
the type assigned by sema (and is visible with sizeof(__func__) for
example) has nothing to do with what codegen ends up producing.
We should eventually add a method on PredefinedExpr to handle this.
In the meantime, just set up some framework and add some fixme's.

Douglas Gregor deaad8cc34 Create a new TypeNodes.def file that enumerates all of the types,
giving them rough classifications (normal types, never-canonical
types, always-dependent types, abstract type representations) and
making it far easier to make sure that we've hit all of the cases when
decoding types. 

Switched some switch() statements on the type class over to using this
mechanism, and filtering out those things we don't care about. For
example, CodeGen should never see always-dependent or non-canonical
types, while debug info generation should never see always-dependent
types. More switch() statements on the type class need to be moved 
over to using this approach, so that we'll get warnings when we add a
new type then fail to account for it somewhere in the compiler.

As part of this, some types have been renamed:

  TypeOfExpr -> TypeOfExprType
  FunctionTypeProto -> FunctionProtoType
  FunctionTypeNoProto -> FunctionNoProtoType

There shouldn't be any functionality change...

Daniel Dunbar 8eb018ab9c Support IRgen of sqrt -> llvm.sqrt, pow -> llvm.pow.
- Define pow[lf]?, sqrt[lf]? as builtins.

 - Add -fmath-errno option which binds to LangOptions.MathErrno

 - Add new builtin flag Builtin::Context::isConstWithoutErrno for
   functions which can be marked as const if errno isn't respected for
   math functions. Sema automatically marks these functions as const
   when they are defined, if MathErrno=0.

 - IRgen uses const attribute on sqrt and pow library functions to
   decide if it can use the llvm intrinsic.
