@llvm/pr-subscribers-backend-powerpc Author: Sergei Barannikov (s-barannikov) ChangesThis allows SDNodes to be validated against their expected type profiles and reduces the number of changes required to add a new node. The validation functionality has detected a few issues, see Most of the nodes have a description in Part of #119709. Patch is 70.58 KiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/168108.diff 10 Files Affected:

This allows SDNodes to be validated against their expected type profiles and reduces the number of changes required to add a new node.
The validation functionality has detected a few issues, see
PPCSelectionDAGInfo::verifyTargetNode().Most of the nodes have a description in
*.tdfiles and were successfully "imported". Those that don't have a description are listed in the enum inPPCSelectionDAGInfo.td. These nodes are not validated.Part of #119709.
