================
Comment at: llvm/docs/GlobalISel/GenericOpcode.rst:802-803
+Generates a pointer to the address of the jump table specified by the source
+operand. The source operand is a jump table index. A jump table is an array
+of addresses the CPU should jump to based on certain conditions.
+G_JUMP_TABLE can be used in conjunction with G_BRJT to support jump table
----------------
I don't think this sentence really fits in this doc. If the user doesn't know what a jump table is then it's better to go read about it in a more detailed source that here. Otherwise, LGTM.
