Problem with PM_DECLARE_TUPLE_TYPE(0) and #line directive.

[GilRoss]

1. The macro:

 

*****

/** Tuple object declaration macro (used by output of pmCoCreator.py) */
#define PM_DECLARE_TUPLE_TYPE(n) \
    typedef struct PmTuple ## n ## _s \
    { \
        PmObjDesc_t od; \
        int16_t length; \
        pPmObj_t val[n]; \
    } PmTuple ## n ## _t
*****

causes problems when n = 0. For example: PM_DECLARE_TUPLE_TYPE(0);. The IAR compiler does not like pPmObj_t val[n]; when n = 0.

 

 

2. The IAR compiler is generating warnings for the following auto-generated line of C code:

 

#line 24 "C:\Projects\TouchKit\CBComm\Mpc04Firmware\..\shared\python2\src\lib\list.py"

 

The warning is: "Warning[Pe192]: unrecognized character escape sequence C:\Projects\TouchKit\CBComm\Mpc04Firmware\pm_generated_objs.c 47".

 

Thanks,

Gil

A workaround for #1 would be to have all your code auto-generated, then manually edit the Tuple0 instance. There will only be one of them.

For #2, I believe IAR has the ability to selectively turn off warnings. I know that's not a great solution, but if you don't have a code-based workaround, then it's the way to go. IAR may also have a different syntax for the #line directive. I don't have an IAR manual anymore so you'll have to hunt.

Okay, I see how I can fix this. It'll just be a special case in the code generator. I'm working on it: http://code.google.com/p/python-on-a-chip/issues/detail?id=238

Okay, I solved #1. But #2 is something you're going to have to figure out.
