Hunt <hunt@pizza.cygnus.com> + + * interp.c (sim_size): Now allocates unified memory for imap segments + 0,1,2, and 127. Initializes imap0 and imap1 to 0x1000. Initializes dmap to 0. + (sim_write): Just call xfer_mem(). + (sim_read): Just call xfer_mem(). + (xfer_mem): New function. Does appropriate memory mapping and copies bytes. + (dmem_addr): New function. Reads dmap register and translates data + addresses to local addresses. + (pc_addr): New function. Reads imap register and computes local address + corresponding to contents of the PC. + (sim_resume): Change to use pc_addr(). + (sim_create_inferior): Change reinitialization code. Also reinitializes + imap[01] and dmap. + (sim_fetch_register): Add fake registers 32,33,34 for imap0, imap1, and dmap. + (sim_store_register): Add fake registers 32,33,34 for imap0, imap1, and dmap. + + * simops.c (MEMPTR): Redefine to use dmem_addr(). + (OP_5F00): Replace references to STate.imem with dmem_addr(). + + * d10v-sim.h (State): Remove mem_min and mem_max. Add umem[128]. + (RB,SW,RW,SLW,RLW): Redefine to use dmem_addr(). + (IMAP0,IMAP1,DMAP,SET_IMAP,SET_IMAP1,SET_DMAP): Define. + +Tue Oct 22 15:22:33 1996 Michael Meissner <meissner@tiktok.cygnus.com> + + * d10v_sim.h (_ins_type): Reorganize, so that we can provide + better statistics, like not counting NOPS as parallel + instructions, and printing total cycles. + (ins_type_counters): Make unsigned long. + (left_nops,right_nops): Fold into ins_type_counters. + + * simops.c (trace_input_func): Print new instruction types. + Handle OP_R2R3 as input types. + (OP_{38000000,7000}): Correctly sign extend bytes. + (OP_5E00): Don't count NOPs as parallel instructions. + (OP_460B): Remove unused variable. + (OP_5F00): Ditto. + + * interp.c (ins_type_counters): Make unsigned long. + (left_nops,right_nops): Delete. + (most functions): Add prototypes. + (INLINE): If GCC and optimize define as __inline__. + ({,lookup_}hash,get_operands): Declare as INLINE. + (do_parallel): Count conditional operations. + (add_commas): New function, to add commas every 3 digits. + (sim_size): Call add_commas to print numbers. + (sim_{open,resume}): Delete unused variables. + (sim_info): Provide better statistics. + (sim_read): Add int return type. + Mon Oct 21 16:16:26 1996 Martin M.
