Hi Philipp, I only use sdcc for the 8051 series of microcontrollers.

Do you mean stuff like this (I do not really know what you mean by "pointer arithmetic") : i2cdat = i2cmsg.buffer[datacount]; or serial_rbuf[(serial_rpos + serial_rcnt++) % serial_rbuflen] = c; Then yes. > * Do they contain array accesses ? See above. > * Do they contain shifts ? On occasion. > * Do they call other functions ? No, and I do my best to keep it like that. I think it is a bad programming practice to call another function from a interrupt service routine. > * Are those other called functions static ? > * Do those other called functions contain divisions ? Not relevant, see above. For my I2C bus interrupt routine I use a switch case. And in my timer interrupt routines I use multiple semaphores controlled by global variables which count down to zero every time the interrupt routine is entered. And further the usual comparisons of a variable to a value and so on. roelof ------------------------------------------------------------------------------ _______________________________________________ Sdcc-user mailing list Sdcc-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sdcc-user
