Hi,
I have a wiring situation that looks like the folowing (simplified):
generic component A generic component A
(instance 1) (instance 2)
| | interface I1<uint16_t>
+---> component B <-------+
| interface I2
+--> configuration C
(contains component D providing I2)
Compiling this results in the following warnings:
nesc1: warning: calls to I2.method1 in B fan out, but there is no combine
function specified for the return type
...
The generated app.c contains:
inline static void *B$I2$method1(message_t *arg_0xb78dd4e8, uint8_t
arg_0xb78dd670){
#line 17
void *result;
#line 17
#line 17
result = D$I2$method1(arg_0xb78dd4e8, arg_0xb78dd670);
#line 17
result = D$I2$method1(arg_0xb78dd4e8, arg_0xb78dd670);
#line 17
#line 17
return result;
#line 17
}
Why does nesC complain about a fan-out of interface I2? I believe this should
not happen and the generated app.c seems to support this believe (the 2
so-called fan-out calls are identical).
Making component B generic makes the warnings dissappear, but it duplicates
the code of component B, which is not desired.
Should I just ignore these warnings or is this a bug that is solved in a more
recent nesC compiler? I am using nesc 1.2.8a.
regards
Wouter
