I can only guess. Don't know whether there's someone with more insight. > As I see it, since the address is 16-bit, 'size' is 1. How do we arrive > at 'rightshift' and 'bitsize' entries? No idea what rightshift is doing, you might get an idea by comparing against other relocation types. bitsize should be clear: it's a 16-bit relocation. My guess is that bitsize might be different for other relocations even with the same 'size' field; compare that e.g. to the relative branch and jump relocations (R_AVR_7_PCREL and R_AVR_13_PCREL). > And how assembler knows to emit > R_AVR_16 type? Probably from the instruction it is connected with. Obviously, R_AVR_16 only applies to instructions like STS/LDS etc. -- cheers, J"org .-.-. --... ...-- -.. .
