Section 8 Applicable Tool Chain and Partner Tools

With the M16C/62P and M16C/6N Groups E8 emulator, you can debug a module created by the inhouse tool chain and

third-party products listed in Table 8.1 below.

Table 8.1 Applicable Tool Chain and Partner Tools

Tool chain M3T-NC30WA V.5.20 Release 01 or later

Partner tools TASKING M16C C/C++/EC++ Compiler V.2.3r1 or later

IAR EWM16C V.2.12 or later

[Precautions on debugging the load modules created in ELF/DWARF2 format]

If the load module was created in ELF/DWARF2 format using TASKING M16C C/C++/EC++ compiler V3.0r1, the

precaution described below must be observed when displaying member variables of the base class in the watch window.

If any class object that has a base class is defined, the following problems may occur:

Case 1: Member variables of the base class cannot directly be referenced from the class object (*1).

Case 2: If the PC value resides in any member function of a derived class, member variables of the base class cannot

directly be referenced (*4).

If member variables of the base class need to be referenced in the watch window, follow either method described

below.

Case 1: Use indirect references from the class object to refer to member variables of the base class (*2) (*3).

Case 2: Use indirect references from “this” pointer to refer to member variables of the base class (*5) (*6).
