Chris Lattner 392be58cad Add support for a union type in LLVM IR. Patch by Talin!

Chris Lattner a0566979b7 Final step in the metadata API restructuring: move the 
getMDKindID/getMDKindNames methods to LLVMContext (and add
convenience methods to Module), eliminating MetadataContext.
Move the state that it maintains out to LLVMContext.

Jeffrey Yasskin 28f244863e This fixes a memory leak in OpaqueType found by Google's internal heapchecker.

Chris Lattner 45d040bd85 Remove isPod() from DenseMapInfo, splitting it out to its own 
isPodLike type trait.  This is a generally useful type trait for
more than just DenseMap, and we really care about whether something
acts like a pod, not whether it really is a pod.

Chris Lattner 37536b90e1 remove a bunch of locking from LLVMContextImpl. Since only one thread 
can be banging on a context at a time, this isn't needed.  Owen, please
review.

Chris Lattner 31b132c0b7 IR support for the new BlockAddress constant kind. This is 
untested and there is no way to use it, next up: doing battle
with asmparser.

Jeffrey Yasskin f6ee7bea88 Rename lib/VMCore/ConstantsContext.h:ValueMap<> to ConstantUniqueMap<> to avoid 
colliding with llvm/ADT/ValueMap.h:ValueMap<>.

Devang Patel 27e0be274e Derive metadata hierarchy from Value instead of User. 
llvm-svn: 84801
 2009-10-21 23:57:35 +00:00
Owen Anderson 5dab84ca9c Banish ConstantsLock. It's serving no purpose other than slowing things down 
at the moment.

Devang Patel d5497a4bf8 Add llvm::Metadata to manage metadata used in a context. 
This interface will be used to attach metadata with an instruction.

Devang Patel f7188325ef Now Bitcode reader bug is fixed. Reapply 80839. 
Use CallbackVH, instead of WeakVH, to hold MDNode elements.
Use FoldingSetNode to unique MDNodes in a context.
Use CallbackVH hooks to update context's MDNodeSet appropriately.

Devang Patel c180029be4 Revert 80839 for now. It causes test failures.

Devang Patel 36309cd391 Use CallbackVH, instead of WeakVH, to hold MDNode elements. 
Use FoldingSetNode to unique MDNodes in a context.
Use CallbackVH hooks to update context's MDNodeSet appropriately.

Devang Patel 8c7f86e698 For now disable MDNode uniquing. This fixes llvm-gcc bootstrap failure on certain Mac OS X 10.5. I am working on a proper fix.

Torok Edwin d18e668fbc Free the constants that have no uses in ~LLVMContext. 
This fixes leaks from LLVMContext in multithreaded apps.
Since constants are only deleted if they have no uses, it is safe to not delete
a Module on shutdown, as many single-threaded tools do.
Multithreaded apps should however delete the Module before destroying the
Context to ensure that there are no leaks (assuming they use a different context
for each thread).

Dan Gohman 97d2cb8394 Allocate the basic types inside the LLVMContextImpl instance, 
rather than separately with new. Move the members above the
TypeMap members to avoid destruction order issues. This fixes
a leak of these objects, and eliminates an extra level of
indirection in Type::getInt32Ty and friends.

actually added.

Owen Anderson 3042539089 Privatize part of the leak detector mechanism, which turned out to be heavily contended 
when trying to run opt in parallel.  This lets parallel opt crunch 403.gcc in about a third
of the time.

 2009-08-19 00:37:02 +00:00
Owen Anderson e8f2185a2f Privatize the ValueHandle global map. Because this is used so heavily throughout the code base, locking all accesses to 
it is not practical performance-wise.

llvm-svn: 79355
 2009-08-18 18:28:58 +00:00

Owen Anderson afd0c4cd56 Factor some of the constants+context related code out into a separate header, to make LLVMContextImpl.h 
not hideous.  Also, fix some MSVC compile errors.

llvm-svn: 78115
