Hi

I seem to have a problem with code generated to access field of a struct in idata.

With a shared header.h file containing:

typedef unsigned int INT16_U;

typedef struct
{
...

INT16_U TZSamplingTicks;
...

}TT_LOGGING_STATE_VECTOR;

extern TT_LOGGING_STATE_VECTOR idata StateVector;

and sleepB3.c containing

TT_LOGGING_STATE_VECTOR idata StateVector;

INT16_U SleepTicksChunk;

The assignment:

396 2 SleepTicksChunk = StateVector.TZSamplingTicks;

generates the following code:

; SOURCE LINE # 396
005E 850000 R MOV StateVector+01BH,SleepTicksChunk
0061 850000 R MOV StateVector+01CH,SleepTicksChunk+01H

The above code fails to make the required assignment.

It appears to me that the necessary indirection is absent, and the effect of the MOV statements will be to pick up the bytes at the same addresses in data, rather than idata.

Is this perhaps an error in your compiler?

I am using version RC51 Compiler 6.14.12.0087

Thank you

Damien
