  "message": "[SimplifyCFG] HoistThenElseCodeToIf(): don\u0027t hoist if either block has it\u0027s address taken\n\nThis problem is exposed by D104598, after it tail-merges `ret` in\n`@test_inline_constraint_S_label`, the verifier would start complaining\n`invalid operand for inline asm constraint \u0027S\u0027`.\n\nEssentially, taking address of a block is mismodelled in IR.\nIt should probably be an explicit instruction, a first one in block,\nthat isn\u0027t identical to any other instruction of the same type,\nso that it can\u0027t be hoisted.\n",
