byte-swapping unnecessary. Add -sparclite-board option for emulating RAM found on typical SPARClite boards. Print error message for unrecognized option. * erc32.c: Change RAM address and size from constants to variables, to allow emulation of SPARClite board RAM. (fetch_bytes, store_bytes): New helper functions for revamped mememory_read and memory_write. (memory_read, memory_write): Rewrite to store bytes in target byte order instead of storing words in host byte order; this greatly simplifies support of little-endian programs. (get_mem_ptr): Remove unnecessary byte parameter. (sis_memory_write, sis_memory_read): Store words in target byte order instead of host byte order. (byte_swap_words): Remove, no longer needed. * sis.h ((byte_swap_words): Remove declaration, no longer needed. (memory_read): Add new sz parameter. * sis.c (run_sim): Use revamped memory_read, which makes byte-swapping unnecessary. * exec.c (dispatch_instruction): Use revamped memory_read, which makes byte-swapping and double-word fetching unnecessary. * func.c (sparclite_board): Declare new variable. (get_regi): Handle little-endian data. (bfd_load): Recognize little-endian SPARClite as having little-endian data. |
