Message:

giet_vm optimizations:

• Several modifications in GIET_VM in order to support compilation with GCC optimizations (-O2) activated.

• Adding missing volatile in some global variables.

• Using ioread and iowrite utility functions in peripheral drivers which prevent GCC to remove writes or reads in hardware memory mapped registers.

• Code refactoring of stdio printf functions. Now, shr_printf and tty_printf function reuse the same function body. The only difference is that shr_printf wraps printf function call with TTY get lock and release lock.
