Athira Rajeev 2c9db7475e perf annotate: Set instruction name to be used with insn-stat when using raw instruction ... Since the "ins.name" is not set while using raw instruction, 'perf annotate' with insn-stat gives wrong data: Result from "./perf annotate --data-type --insn-stat": Annotate Instruction stats total 615, ok 419 (68.1%), bad 196 (31.9%) Name : Good Bad ----------------------------------------------------------- : 419 196 This patch sets "dl->ins.name" in arch specific function "check_ppc_insn" while initialising "struct disasm_line". Also update "ins_find" function to pass "struct disasm_line" as a parameter so as to set its name field in arch specific call.
