R600/SI: Add a stub GCNTargetMachine This is equivalent to the AMDGPUTargetMachine now, but it is the starting point for separating R600 and GCN functionality into separate targets. It is recommened that users start using the gcn triple for GCN-based GPUs, because using the r600 triple for these GPUs will be deprecated in the future. llvm-svn: 225277

Fix classof for ISD::INTRINSIC_W_CHAIN and INTRINSIC_VOID Unfortunately, our use of the SDNode class hierarchy for INTRINSIC_W_CHAIN and INTRINSIC_VOID nodes is somewhat broken right now. These nodes sometimes are used for memory intrinsics (those with MachineMemOperands), and sometimes not. When not, the nodes are not created as instances of MemIntrinsicSDNode, but rather created as some other subclass of SDNode using DAG::getNode. When they are memory intrinsics, they are created using DAG::getMemIntrinsicNode as instances of MemIntrinsicSDNode. MemIntrinsicSDNode is a subclass of MemSDNode, but prior to r214452, we had a non-self-consistent setup whereby MemIntrinsicSDNode::classof on INTRINSIC_W_CHAIN and INTRINSIC_VOID would return true but MemSDNode::classof on INTRINSIC_W_CHAIN and INTRINSIC_VOID would return false. In r214452, MemSDNode::classof was changed to return true for INTRINSIC_W_CHAIN and INTRINSIC_VOID, which is now self-consistent. The problem is that neither the pre-r214452 logic and the post-r214452 logic are really right. The truth is that not all INTRINSIC_W_CHAIN and INTRINSIC_VOID nodes are instances of MemIntrinsicSDNode (or MemSDNode for that matter), and the return value from classof needs to reflect that. This was broken before r214452 (because MemIntrinsicSDNode::classof always returned true), and was broken afterward (because MemSDNode::classof also always returned true), and will now be correct. The minimal solution is to grab one of the SubclassData bits (there is one left for MemIntrinsicSDNode nodes) and use it to store whether or not a particular INTRINSIC_W_CHAIN or INTRINSIC_VOID is really an instance of MemIntrinsicSDNode or not. Doing this allows both MemIntrinsicSDNode::classof and MemSDNode::classof to return the correct answer for the underlying object for both the memory-intrinsic and non-memory-intrinsic cases. This fixes the problem that r214452 created in the SelectionDAGDumper (thanks to Matt Arsenault for pointing it out). Because PowerPC does not implement getTgtMemIntrinsic, this change breaks test/CodeGen/PowerPC/unal-altivec-wint.ll. I've XFAILed it for now, and will fix it in a follow-up commit. llvm-svn: 215511

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction Essentially the same as the GEP change in r230786. A similar migration script can be used to update test cases, though a few more test case improvements/changes were required this time around: (r229269-r229278) import fileinput import sys import re pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)") for line in sys.stdin: sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line)) Reviewers: rafael, dexonsmith, grosser Differential Revision: http://reviews.llvm.org/D7649 llvm-svn: 230794
