| | | | | | | | | | | | Make MDNode::destroy private. Fix the one thing that used MDNode::destroy, outside of MDNode itself. One should never delete or destroy an MDNode explicitly.

* Optimize MDNode to coallocate the operand list immediatelyChris Lattner2009-12-311-5/+11
| | | | | | | | | | | | | | 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

| | | | | | | | | 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

| | | | | | | | | | | | | 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
* This is a major cleanup of the instruction metadata interfaces thatChris Lattner2009-12-281-19/+1
| | | | | | | | | | | | | | | | | | | | | | | 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
