Today I tried this again and it also fails on x86 (seems I didn't update the VM the last time). I think the reason for this is that we also have to load the basicType of mtype and compare these two: // fetch mtype.form.basicType load_heap_oop(Address(mtype_reg, delayed_value(java_lang_invoke_MethodType::form_offset_in_bytes, temp3_reg)), temp2_reg); load_heap_oop(Address(temp2_reg, delayed_value(java_lang_invoke_MethodTypeForm::basicType_offset_in_bytes, temp3_reg)), temp2_reg); // fetch mh.type.form.basicType load_heap_oop(Address(temp_reg, delayed_value(java_lang_invoke_MethodType::form_offset_in_bytes, temp3_reg)), temp_reg); load_heap_oop(Address(temp_reg, delayed_value(java_lang_invoke_MethodTypeForm::basicType_offset_in_bytes, temp3_reg)), temp_reg); cmp_and_brx_short(temp_reg, temp2_reg, Assembler::notEqual, Assembler::pn, wrong_method_type); Correct? -- Chris > > -- Chris > >> _______________________________________________ >> mlvm-dev mailing list >> mlvm-dev@openjdk.java.net >> http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev > > _______________________________________________ > mlvm-dev mailing list > mlvm-dev@openjdk.java.net > http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
