[PATCH] D98464: [GlobalISel] Add G_SBFX + G_UBFX (bitfield extraction opcodes)

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/include/llvm/Target/GenericOpcodes.td:1348
+  let OutOperandList = (outs type0:$dst);
+  let InOperandList = (ins type0:$src, unknown:$lsb, unknown:$width);
+  let hasSideEffects = false;
----------------
These can be registers like a normal op. AMDGPU has registers/variable inputs for the offset and width
