Both CPUClass::gdb_read_register() and CPUClass::gdb_write_register()
handlers are called from common gdbstub code, and won't be called with
register index over CPUClass::gdb_num_core_regs:
int gdb_read_register(CPUState *cpu, GByteArray *buf, int reg)
{
CPUClass *cc = CPU_GET_CLASS(cpu);
if (reg < cc->gdb_num_core_regs) {
return cc->gdb_read_register(cpu, buf, reg);
}
...
}
static int gdb_write_register(CPUState *cpu, uint8_t *mem_buf, int reg)
{
CPUClass *cc = CPU_GET_CLASS(cpu);
if (reg < cc->gdb_num_core_regs) {
return cc->gdb_write_register(cpu, mem_buf, reg);
}
...
}
Clarify that in CPUClass docstring, and remove unreachable code on
the microblaze and openrisc implementations.
