Funny. As far back as I remember we consistently said that bits of the same word, but outside the subreg are left with undefined values after storing into the subreg, except if wrapped with a strict_low_part. In fact that's the whole point of strict_low_part. I'm pretty sure we assume this documented semantics in various parts of the compiler.
You both are correct. AVR has /* Width of a word, in units (bytes). */ #define UNITS_PER_WORD 1 Paolo
