Anders Carlsson a30c0d3ace Use a PointerIntPair for the PrimaryBaseInfo. Yay for clever LLVM data structures!

Anders Carlsson 03ff379911 Add a new PrimaryBaseInfo struct that combines the record decl of a primary base with whether it's virtual or not.

Anders Carlsson ba958400a2 When laying out bitfields, make sure that the data size is always aligned to a byte. This fixes PR5580.

Alexis Hunt 96d5c76498 Added rudimentary C++0x attribute support.
The following attributes are currently supported in C++0x attribute
lists (and in GNU ones as well):
 - align() - semantics believed to be conformant to n3000, except for
   redeclarations and what entities it may apply to
 - final - semantics believed to be conformant to CWG issue 817's proposed
   wording, except for redeclarations
 - noreturn - semantics believed to be conformant to n3000, except for
   redeclarations
 - carries_dependency - currently ignored (this is an optimization hint)

Sebastian Redl 1054faed32 Audit the code for places where it is assumed that every base specifier refers to a RecordType. Add assertions or conditions as appropriate. This fixes another crash in the Apache stdlib vector.

Anders Carlsson e1883100a3 Who would have thought that empty classes were so tricky? Handle cases where an empty virtual base class needs to be moved aside because it conflicts with the first field.

Mike Stump 590a7c780c We can't avoid doing the work to find all the indirect primary virtual
base classes as we'll need that to layout the virtual bases...

Mike Stump 78696a70bf Implement more of the inductive case for vtable layout involving
virtual base primaries and improve the layout of classes with virtual
bases.  WIP.

Hey, I've decided I want a change to FileCheck, I need to ensure that
the group is together, nothing in between.  Can we change it to check
the match line is from the line immediately following the last matched
line, if the source for the matched line is immediately after the
source for the previously matched line?

// CHECK: 1
// CHECK: 2
// CHECK: 3

// CHECK: 4
// CHECK: 5
// CHECK: 6

would require 1 2 and 3 to be continuous in the output, and 4 5 and 6
to be continuous.

Anders Carlsson 28a5fa29f3 Take #pragma pack into account when laying out structs. Fixes rdar://problem/7095436.
llvm-svn: 78490
2009-08-08 19:38:24 +00:00
Anders Carlsson 68e0b68289 Introduce a new PragmaPack attribute, and use it for #pragma pack. The PackedAttr now only represents __attribute__((packed)).
This is necessary because #pragma pack and __attribute__((packed)) have different semantics. No functionality change yet, but this lays the groundwork for fixing a record layout bug.

llvm-svn: 78483

virtual base layout.

Mike Stump 57724c2f7e Update based upon comments. Explain why we have an assert.
llvm-svn: 77612
2009-07-30 18:01:44 +00:00
Mike Stump 44b8e90369 We'll also need a vtable pointer if we have virtual bases.
llvm-svn: 77610
2009-07-30 17:53:53 +00:00
Mike Stump 3dc7eb9440 Add ability to layout the vtable pointer in trivial cases. I noticed
that we would silently do bad things with virtual bases in the layout
code, so, we just turn them off.  When people do better things with
them, we can turn them back on.

Ted Kremenek c23c7e6a51 Change uses of:
Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsRecordType() -> Type::getAs<RecordType>()
  Type::getAsPointerType() -> Type::getAs<PointerType>()
  Type::getAsBlockPointerType() -> Type::getAs<BlockPointerType>()
  Type::getAsLValueReferenceType() -> Type::getAs<LValueReferenceType>()
  Type::getAsRValueReferenceType() -> Type::getAs<RValueReferenceType>()
  Type::getAsMemberPointerType() -> Type::getAs<MemberPointerType>()
  Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsTagType() -> Type::getAs<TagType>()
  
And remove Type::getAsReferenceType(), etc.

This change is similar to one I made a couple weeks ago, but that was partly
reverted pending some additional design discussion. With Doug's pending smart
pointer changes for Types, it seemed natural to take this approach.
