* interp.c (sim_resume): Increment PC at end of rep loop. * simops.c (OP_4201): Fix rachi instruction.
1997-09-05* configure: Regenerated to track ../common/aclocal.m4 changes.David Edelsohn2-71/+307
1997-08-27Fix doco on enable-sim-inline.Andrew Cagney1-0/+5
1997-08-27Add ABFD argument to sim_create_inferior. Document.Andrew Cagney2-7/+15
Add file sim-hload.c - generic load for hardware only simulators. Review each simulators sim_open, sim_load, sim_create_inferior so that they more closely match required behavour.
1997-08-26Flush defunct sim_kill.Andrew Cagney2-7/+4
1997-08-25Add ABFD argument to sim_open call. Pass through to sim_config soAndrew Cagney2-8/+23
that image properties such as endianness can be checked. More strongly document the expected behavour of each of the sim_* interfaces. Add default endian argument to simulator config macro SIM_AC_OPTION_ENDIAN. Use in sim_config.
1997-04-22 * interp.c (sim_open): Undo patch to add -E support.David Edelsohn1-0/+4
1997-04-18Ref gdb/11763 - can't stop a running simulator:Andrew Cagney2-0/+13
o Provide poll_quit callback to simulators so that they can poll for SIGINT on clueless OS's. o Add sim_stop to simulators so that clients can request a halt (eg gdbtk's STOP button) Works for PPC! o Re-arange remote-sim.c so that the hard work is moved from gdbsim_resume() to gdbsim_wait() (where it should be).
1997-04-17 * Makefile.in (SIM_OBJS): Add sim-load.o.David Edelsohn2-59/+114

Delete arg start_address. (sim_load): Return SIM_RC. New arg abfd. Set start address from bfd. Call sim_load_file to load file into simulator. * simops.c (trace_input_func): exec_bfd renamed to prog_bfd.

* Make-common.in (CSEARCH): Do not include the gdb directory in the search path. * Make-common.in (SIM_ENDIAN, SIM_HOSTENDIAN, SIM_INLINE, SIM_WARNING): Drop, requiring the simulator specific Makefile.in to explicitly incorporate these. * aclocal.m4 (--enable-sim-alignment); New option.

Conditionally compile in assertion statements. (--enable-sim-float): New option. Strongly specify the target's floating point support. (--enable-sim-hardware): New option. Specify the hardware devices included in the simulation. (--enable-sim-packages): New option. Specify the hardware packages included in the simulation. (--enable-sim-regparm): New option.

* d10v-sim.h (simops): Add flag is_long. (State): Add pc_changed. Instructions which update the PC should use the JMP macro which sets this. (JMP): New macro. Sets the PC and the pc_changed flag. * gencode.c (write_opcodes): Add is_long field. * interp.c (lookup_hash): If we blindly apply a short opcode's mask to a long opcode we could get a false match. Check the opcode size. (hash): Add a size field to the hash table. (sim_open): Initialize size field in hash table. (sim_resume): Change to logic for setting the PC. Used to increment the PC if it had not been changed. This didn't allow single-instruction loops. Now checks the flag State.pc_changed. Also now stops when ^C is received. (dmem_addr): Fix translation of data segments to unified memory. (sim_ctrl_c): New function. When ^C is received, set stop_simulator flag. * simops.c: Changed all branch and jump instructions to use new JMP macro. (OP_20000000): Corrected trace information to show this is a ldi.l, not a ldi.s instruction.

* interp.c (sim_fetch_register, sim_store_register): Fix bug where updating the accumulators was overwriting other parts of the global State variable.

1996-10-29Tue Oct 29 12:13:52 1996 Martin M. Hunt <hunt@pizza.cygnus.com>Martin Hunt4-143/+439
* 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.
