Mike Stump 4446dcf061 prep work for copy/destroy helpers for block literals. 
llvm-svn: 66159
 2009-03-05 08:32:30 +00:00
Mike Stump 626aecc4be Add codegen support for __block variables to call _Block_object_dispose as necessary. 
llvm-svn: 66117
 2009-03-05 01:23:13 +00:00
Mike Stump 2d33d6300c Fixup __block codegen in nested block literals. 
llvm-svn: 66091
 2009-03-04 22:48:06 +00:00
Mike Stump 06acea8a69 Move some of the CodeGenFunction blocks code up and out. No 
functionality change.

llvm-svn: 66048
 2009-03-04 18:57:26 +00:00
Mike Stump 6c39666a77 Move more of the blocks code up and out. 
llvm-svn: 66046
 2009-03-04 18:47:42 +00:00
Mike Stump 95435674f9 Move more of blocks codegen out of CodeGenModule and into the 
BlockModule.  No functionality change.  This should help people that
don't want to know anything about blocks not be confused by the
overloaded use of the term block or nor want to see all the blocks
goop.

llvm-svn: 66042
 2009-03-04 18:17:45 +00:00
Mike Stump 0874160bd5 Add __block codegen testcase. We introduce a temporary flag to enable 
codegen, until such time as codegen is complete enough to turn on with
-fblocks.

llvm-svn: 66031
 2009-03-04 13:17:22 +00:00
Mike Stump 97d01d50d9 Improved ABI compliance for __block variables. No testcases yet as we 
still give an unsupported error for them due to the fact this is a
work in progress.

Daniel Dunbar dd9427133a Avoid crash when child iterator gives null result. 
llvm-svn: 65812
 2009-03-02 07:00:57 +00:00
Mike Stump 0e425b8200 Push checking down, also, give the user a hit as to which part of the 
block literal is causing the problem, instead of the vague reference
to the entire block literal.

llvm-svn: 65798
 2009-03-02 03:04:42 +00:00
Anders Carlsson 5878c797b3 Add BLOCK_HAS_DESCRIPTOR to global blocks. 
llvm-svn: 65788

Anders Carlsson 3113eedc8a Remove debugging code. 
llvm-svn: 65753
 2009-03-01 02:12:54 +00:00
Anders Carlsson 961763e35a Emit errors about unsupported blocks features. 
llvm-svn: 65751
 2009-03-01 01:45:25 +00:00
Anders Carlsson ed5e69fe50 Do some blocks cleanup and simplification. Fix a crash, and add a test case. 
llvm-svn: 65746
 2009-03-01 01:09:12 +00:00
Chris Lattner 3385fe12ce improve compatibility with the VC++'08 C++ compiler. Patch by 
Niklas Larsson!

llvm-svn: 65706
 2009-02-28 19:01:03 +00:00
Mike Stump 1db7d04b71 First cut CodeGen support for __block variables. 
llvm-svn: 65688
 2009-02-28 09:07:16 +00:00
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...

Mike Stump b750d928ce CodeGen support for copied BlockDeclRefExprs. 
llvm-svn: 65487
 2009-02-25 23:33:13 +00:00
Anders Carlsson b9c9e1d16f Pass the CodeGenModule object to GenerateBlockFunction, instead of *this (which will call the copy constructor). 
Also, since we're creating a new CodeGenFunction object for each block function, we don't need to clear the BreakContinueStack.

llvm-svn: 65371
 2009-02-24 04:19:41 +00:00
Mike Stump 18e91257e4 Ensure that we can't break or continue out of a block.

Mike Stump 2ac40a9ff8 The blocks ABI is wrong, add a FIXME. 
llvm-svn: 65243
 2009-02-21 20:07:44 +00:00
Mike Stump cb2fbcb0c9 Add CodeGen support for the helper for BlockDeclRefExprs. The easier 
stuff is mostly done.  Move BlockHasCopyDispose up.

llvm-svn: 65242
 2009-02-21 20:00:35 +00:00
Mike Stump 5d2534ada7 More codegen for blocks. The type of block literals should be better. 
The size calculation is improved.

Mike Stump eecd39f2d7 Avoid getNameAsCString when the decl doesn't have a name. 
Build of the parm list with the iterator, not end().
