Embedded JIT mode for Pico Continuation of: - #1829 - #1838 - #1881 - #1891 - #1893 - #1900 - #1901 - #1903 - #1907 Add the ability to perform just in time compilation directly on Raspberry Pi Pico. Erlang bytecode is compiled to armv6m on the first run and directly executed on subsequent runs. In this PR, the native code compilation does not take advantage of being done on the device, it still generates position independent code. If Erlang modules include `Type` chunk, the same optimizations that happen on the desktop with precompilation could be done on the Pico, however current release (0.7.5) of [`packbeam`](https://github.com/atomvm/atomvm_packbeam) prunes the `Type` chunk. Just in time compilation on the Pico is achieved by: - Adding a flush call after JIT is performed, which is noop on all platforms except on armv6m where we flush the literal pool (normally a noop, though, as the pool should have been flushed earlier). - Updating avm API to fetch the last section named end. - Adding a `jit_stream_flash` for RP2 platform and adding a cache native code mechanism that rely on the avm end section on RP2 to find out where to flash jit code (after the last end) and detect if avm were updated.
