Follow-up Comment #3, bug #37778 (project avr-libc): Question is whether or not NOP should be allowed to be moved across ordinary memory moves.
For SEI and CLI, for example, I think this is not wanted in general. NOP is less intrusive than SEI / CLI, of course, but avr-gcc emits __builtin_avr_nop() with a memory clobber: http://gcc.gnu.org/viewcvs/trunk/gcc/config/avr/avr.md?revision=195151&view=markup#l5938 _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?37778> _______________________________________________ Nachricht gesendet von/durch Savannah http://savannah.nongnu.org/ _______________________________________________ AVR-libc-dev mailing list AVR-libc-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/avr-libc-dev
