[PATCH v2 5/5] target/avr: enable icount mode

2023-01-23 Thread Pavel Dovgalyuk
Icount mode requires correct can_do_io flag management for checking that IO operations are performed only in the last TB instruction. This patch sets this flag before every helper which can lead to virtual hardware access. It enables deterministic execution in icount mode for AVR. Signed-off-by: P
