The added ones are: addi, addic, addic., addis, subfic and mulli Reviewed-by: Kajol Jain Reviewed-by: Namhyung Kim Signed-off-by: Athira Rajeev Tested-by: Kajol Jain Cc: Adrian Hunter Cc: Akanksha J N Cc: Christophe Leroy Cc: Disha Goel Cc: Hari Bathini Cc: Ian Rogers Cc: Jiri Olsa Cc: Madhavan Srinivasan Cc: Segher Boessenkool Link: https://lore.kernel.org/lkml/20240718084358.72242-11-atrajeev@linux.vnet.ibm.com Signed-off-by: Arnaldo Carvalho de Melo --- diff --git a/tools/perf/arch/powerpc/annotate/instructions.c b/tools/perf/arch/powerpc/annotate/instructions.c index aa5ee09fa28f..aa25a336d8d0 100644 --- a/tools/perf/arch/powerpc/annotate/instructions.c +++ b/tools/perf/arch/powerpc/annotate/instructions.c @@ -172,6 +172,14 @@ static struct insn_offset arithmetic_ins_op_31[] = { { .name = "DIV_W_XO_FORM", .value = 491, }, }; +static struct insn_offset arithmetic_two_ops[] = { + { .name = "mulli", .value = 7, }, + { .name = "subfic", .value = 8, }, + { .name = "addic", .value = 12, }, + { .name = "addic.", .value = 13, }, + { .name = "addi", .value = 14, }, + { .name = "addis", .value = 15, }, +}; static int cmp_offset(const void *a, const void *b) { @@ -212,6 +220,12 @@ static struct ins_ops *check_ppc_insn(u32 raw_insn) if (PPC_21_30(raw_insn) == 444) return &arithmetic_ops; } + } else { + mem_insns_31_opcode.value = opcode; + ret = bsearch(&mem_insns_31_opcode, arithmetic_two_ops, ARRAY_SIZE(arithmetic_two_ops), + sizeof(arithmetic_two_ops[0]), cmp_offset); + if (ret != NULL) + return &arithmetic_ops; } return NULL;
