acceptable kind with more precise semantics.

native IRgen type is. This is like Default, but without any extra
semantics (like automatic tweaking of structures or void).

llvm-svn: 63615

llvm-svn: 63613

llvm-svn: 63612

 - Still have to convert some consumers over.

llvm-svn: 63610

llvm-svn: 63586

llvm-svn: 63576

llvm-svn: 63571

 - Inefficient & leaks memory currently, will be cleaned up subsequently.

llvm-svn: 63567

 - Lift CGFunctionInfo creation above ReturnTypeUsesSret and
   EmitFunction{Epi,Pro}log.

llvm-svn: 63553

 - Lift CGFunctionInfo creation up to callers of EmitCall.

 - Move isVariadic bit out of CGFunctionInfo, take as argument to
   GetFunctionType instead.

No functionality change.

function/call info.

in terms of where the type resides in the containing object. This is a
more clear embodiement of the spec & fixes a merging issue with
unions. Down to 3/1000 failures.

llvm-svn: 63455

computing in bytes not bits. We are now down to 22/1000 failures on
the return types tests, and 18 of those are gcc bugs I believe.

llvm-svn: 63438

class, not integer.

llvm-svn: 63426

matches gcc 4.2 (not llvm-gcc).

llvm-svn: 63413

robust enough for general use.

llvm-svn: 63406

x86_64 ABI: Split small vectors which cross an eightbyte boundary. Down to 33/500 return type failures.

llvm-svn: 63404

 - This brings us down to an 8% failure rate on the first 500 return
   types tests (from 12%).

llvm-svn: 63383

llvm-svn: 63352

eightbyte boundaries.
 - Getting harder to test now that we handle cases gcc & llvm-gcc get
   wrong ( { _Complex char; _Complex int; } is a good example). :)

llvm-svn: 63305

we see a Memory classification.

llvm-svn: 63295

to still return an RValue of the correct type.

llvm-svn: 63294

 - This is my best initial guess at what the "spec" means, although it is not
   particularly clear on a number of points. Will refine through testing.

llvm-svn: 63292

(e.g., _Complex double -> { double, double } return).

llvm-svn: 63285

llvm-svn: 63283

 - gcc appears to be classifying <1 x double> as INTEGER which is
   odd. Will investigate later.

llvm-svn: 63086

 - Code quality is poor, but simple.

llvm-svn: 63083

llvm-svn: 63039

 - No functionality change, moved behind -use-x86_64-abi option until
   it becomes non-experimental.

llvm-svn: 62915

llvm-svn: 62268

filters the decls seen by decl_iterator with two criteria: the dynamic
type of the declaration and a run-time predicate described by a member
function. This simplifies EnumDecl, RecordDecl, and ObjCContainerDecl
considerably. It has no measurable performance impact.

llvm-svn: 61994

 - Update comment to reflect fact that StructRet is now supported for
   any type (modulo LLVM support).

 - No functionality change, no scalar types currently use this
   feature.

llvm-svn: 61192

llvm-svn: 60058

NamedDecl::getNameAsString() to make it more explicit.
