Pull request overview
This PR refactors the Forth interpreter to use position-independent code by changing from a statically allocated memory array to dynamic memory allocation at runtime. This enables the code to work correctly regardless of where it's loaded in memory.
Key changes:
- Separated read-only initialization data into a
rodataarray while makingmemoryandbytesdynamically allocated pointers - Added
set_up_data_segment()function to allocate memory viasbrk()and copy the initial data at runtime - Added special handling for
SYS_brksyscall to adjust returned addresses for position independence
