2009-12-31rename "elements" of metadata to "operands". "Elements" areChris Lattner
things that occur in types. "operands" are things that occur in values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92322 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-31Optimize MDNode to coallocate the operand list immediatelyChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92321 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-30do not bother reuniquing mdnodes whose operands drop to null. DoingChris Lattner
so can be a huge performance issue when tearing down modules and mdnodes are not guaranteed to be unique anyway. This speeds up: $ time ~/llvm/Release/bin/clang gcc.c -w -S -g from 72 to 35s, where gcc.c is from: http://people.csail.mit.edu/smcc/projects/single-file-programs/ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92315 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-29Final step in the metadata API restructuring: move the Chris Lattner
getMDKindID/getMDKindNames methods to LLVMContext (and add convenience methods to Module), eliminating MetadataContext. Move the state that it maintains out to LLVMContext. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92259 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-29the only call to this function (from clang) has been removed, zap it.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92254 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-29remove some unneeded Metadata interfaces.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92252 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-29When doing v1->RAUW(v2), don't do anything to metadata. We don't knowChris Lattner
why one was replaced with the other. Even in the specific case of debug information, it doesn't make sense to transfer the location over, this will just result in jumbled loc info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92241 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-29sink the Instruction::HasMetadata bit into SubclassData.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92240 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-29add a layer of accessors around the Value::SubClassData member, and use Chris Lattner
a convention (shadowing the setter with private forwarding function) to prevent subclasses from accidentally using it. This exposed some bogosity in ConstantExprs, which was propaging the opcode of the constant expr into the NUW/NSW/Exact field in the getWithOperands/getWithOperandReplaced methods. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92239 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-28This is a major cleanup of the instruction metadata interfaces thatChris Lattner
I asked Devang to do back on Sep 27. Instead of going through the MetadataContext class with methods like getMD() and getMDs(), just ask the instruction directly for its metadata with getMetadata() and getAllMetadata(). This includes a variety of other fixes and improvements: previously all Value*'s were bloated because the HasMetadata bit was thrown into value, adding a 9th bit to a byte. Now this is properly sunk down to the Instruction class (the only place where it makes sense) and it will be folded away somewhere soon. This also fixes some confusion in getMDs and its clients about whether the returned list is indexed by the MDID or densely packed. This is now returned sorted and densely packed and the comments make this clear. This introduces a number of fixme's which I'll follow up on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92235 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-28Rewrite the function-local validation logic for MDNodes (most of r91708).Chris Lattner
Among other benefits, this doesn't leak the SmallPtrSet, has the verifier code in the verifier pass, actually does the verification at the end, and is considerably simpler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92217 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-18Formalize MDNode's function-localness:Victor Hernandez
- an MDNode is designated as function-local when created, and continues to be even if its operands are modified not to refer to function-local IR - function-localness is designated via lowest bit in SubclassData - getLocalFunction() descends MDNode tree to see if it is consistently function-local Add verification of MDNodes to checks that MDNodes are consistently function-local.
