* fix Analysis/DebugInfo.h to not include Metadata.h. Do thisChris Lattner2009-12-313-0/+7

* metadata can't be a global var initializer.Chris Lattner2009-12-311-4/+0
| | | | llvm-svn: 92330
* simplify mdnode printing logic. Now N->dump() onlyChris Lattner2009-12-311-127/+105
| | | | | | dumps one node instead of all of them. llvm-svn: 92329
* unify two copies of the NamedMDNode printing code.Chris Lattner2009-12-311-25/+22

* simplify asmprinting of NamedMDNodeChris Lattner2009-12-311-34/+4

* Remove #include of metadata.h from intrinsicinst.h. The onlyChris Lattner2009-12-311-0/+8
| | | | | | | method that needs it (DbgValueInst::getValue) has been moved out of line. llvm-svn: 92323
* rename "elements" of metadata to "operands". "Elements" areChris Lattner2009-12-319-102/+102
| | | | | | | things that occur in types. "operands" are things that occur in values. llvm-svn: 92322
* Optimize MDNode to coallocate the operand list immediatelyChris Lattner2009-12-312-36/+50
| | | | | | | | | | | | | after the MDNode in memory. This eliminates the operands pointer and saves a new[] per node. Note that the code in DIDerivedType::replaceAllUsesWith is wrong and quite scary. A MDNode should not be RAUW'd with something else: this changes all uses of the mdnode, which may not be debug info related! Debug info should use something non-mdnode for declarations. llvm-svn: 92321

* do not bother reuniquing mdnodes whose operands drop to null. DoingChris Lattner2009-12-301-9/+27
| | | | | | | | | | | so can be a huge performance issue when tearing down modules and mdnodes are not guaranteed to be unique anyway.

* now that instruction metadata is only parsed in one place, eliminate theChris Lattner2009-12-302-10/+12
| | | | | | | parser-global MDsOnInst vector and make ParseInstructionMetadata return its result by-ref through an argument like the entire rest of the parser. llvm-svn: 92302
* reimplement ParseOptionalInfo as ParseOptionalCommaAlign, correctlyChris Lattner2009-12-302-37/+46
| | | | | | handle the comma case for metadata. llvm-svn: 92301
* rename ParseOptionalCustomMetadata -> ParseInstructionMetadata,Chris Lattner2009-12-302-20/+11
| | | | | | | and make it non-optional. This fixes the bug where we'd accept and ignore a spurious comma after some instructions. llvm-svn: 92300

* rename lltok::Metadata -> lltok::exclaim. We name tokens Chris Lattner2009-12-304-19/+15

* rename MetadataCache -> NumberedMetadata to follow the conventionChris Lattner2009-12-302-17/+18
