I just migrated a project from Keil 3 to Keil 5 (C51 = V9.56.0.0 & LX51 4.66.66.0
I get the following (new) warnings:
*** WARNING L48: IGNORED RECURSIVE CALL CALLED: _SMBUS_SET_PACKET_DATA/SMBUS CALLER: SMBUS *** WARNING L48: IGNORED RECURSIVE CALL CALLED: SMBUS CALLER: _SMBUS_SET_PACKET_DATA/SMBUS
puzzle is that while there is a routine called smbus_set_packet_data there is no routine called smbus. In fact the routine is reproduced below:
static void smbus_set_packet_data(uint8_t pos, uint8_t val,uint8_t info) { smbus_packet[pos] = val; smbus_packet_info[pos] = info; }
What does the above warning indicate?
What exactly did the linker ignore? (Any calling sequence not included in the final binary?
thanks for the clarifications.
In my case the offending function was very small. Ended up removing the function and inserted the instructions. (Cost - about 12 bytes.) YMMV
if you are interested, please email me privately (rsrinivasan at abiomed com) i can share some snippets.
