The jump table info is serialized using a YAML mapping that contains its kind and a YAML sequence of jump table entries. A jump table entry is a YAML mapping that has an ID and an inline YAML sequence of machine basic block references. The testcase 'CodeGen/MIR/X86/jump-table-info.mir' doesn't have any instructions because one of them contains a jump table index operand. The jump table index operands will be serialized in a follow up patch, and the appropriate instructions will be added to this testcase. Reviewers: Duncan P. N.
