1. Description
If member variables of a nested unnamed union are defined using
High-performance Embedded Workshop and any of the following debuggers,
these member variables cannot be referenced by the debugger.
- Simulator debugger for the SuperH RISC engine family
- Simulator debugger for the H8SX, H8S, and H8 families
- E8 emulator software
- E10A-USB emulator software
- E10T-USB emulator software
- E200F emulator software
- E6000H emulator software
- E6000 emulator software
2. Conditions
This problem occurs if the following conditions are all satisfied:
(1) Load modules are created in the ELF/DWARF2 object format.
(2) an unnamed union is nested.
2.1 Example in Type Declaration
union {
unsigned char digit2[2];
unsigned short word2;
union {
unsigned char digit_nested[2]; *
unsigned short word_nested; *
};
};
*The debugger cannot reference the member variables of these nested
unnamed unions.
3. Solution
This problem has been fixed in the High-performance Embedded Workshop
V.4.03.00.
