1997-01-24 * configure: Remove Make-common.in from dependencies. (Actually inStu Grossman1-1/+1
../common/aclocal.m4).
1997-01-23 * configure configure.in Makefile.in: Update to new configureStu Grossman4-270/+417
scheme which is more compatible with WinGDB builds. * configure.in: Improve comment on how to run autoconf. * configure: Re-run autoconf to get new ../common/aclocal.m4. * Makefile.in: Use autoconf substitution to install common makefile fragment.
1996-12-16Mon Dec 16 13:39:03 1996 Martin M. Hunt <hunt@pizza.cygnus.com>Martin Hunt1-0/+9
* interp.c (xfer_mem): Change unified memory to 0x0.
1996-11-26 * config.in (WORDS_BIGENDIAN): Add.David Edelsohn2-88/+383
* configure: Regenerated. * d10v_sim.h: #include "config.h"
1996-11-21Make address in I/O space a bus error; properly cast callocMichael Meissner1-0/+9
1996-11-20New file.David Edelsohn2-0/+5
1996-11-20 * Makefile.in: Delete all stuff moved to ../common/Make-common.in.David Edelsohn3-81/+62
(SIM_OBJS,SIM_EXTRA_CFLAGS,SIM_EXTRA_CLEAN): Define. * configure.in: Simplify using macros in ../common/aclocal.m4. Call AC_CHECK_HEADERS(unistd.h). * configure: Regenerated. * config.in: New file. * interp.c: #include "callback.h". * simops.c: #include "config.h". #include <unistd.h> if present.

* 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.

* 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.

* interp.c (sim_resume): Change the way single-stepping and exceptions are handled so single-stepping works again.
