 675
 676         * configure.in: Recognize m6811-*-*.
 677         * configure: Regenerate.
 678         * m68hc11_sim.h (cpu_ccr_update_add8, cpu_ccr_update_add16,
 679         cpu_ccr_update_sub8, cpu_ccr_update_sub16):
 680         Correct the computation of carry of 8 and 16-bits add and subtract.
 681         * gencode.c: Use cpu_ccr_update_sub8 for subtraction (carry and
 682         overflow set in a different manner than add).

 684 1999-05-14  Stephane Carrez  <stcarrez@worldnet.fr>
 685
 686         * dv-m68hc11.c (dv_m6811_attach_address_callback): Removed a
 687         trace message.
 688         * interp.c (sim_open, sim_create_inferior): Initialize the
 689         cpu_elf_start from the ELF header.
 690         * m68hc11_sim.c (cpu_initialize): Clear the new data members.
 691         (cpu_restart): Use cpu_elf_start as the starting address when
 692         the flag is set.
 693         (cpu_special): When cpu_use_elf_start is set, the WAI instruction
 694         exits the simulator (exit status is in D).
 695         * m68hc11_sim.h (_sim_cpu): Added members cpu_use_elf_start and
 696         cpu_elf_star to start execution at address specified in ELF file.

 699
 700         * Makefile.in, config.in, configure, configure.in: New files.
 701         * gencode.c: New file, generation of 68HC11 interpreter.
 702         * m68hc11_sim.h, m68hc11_sim.c: New files, specific operations
 703         for interpreter.
 704         * interrupts.c, interrupts.h: New files, management of interrupts.
 705         * interp.c, sim-main.h,
 706         * dv-m68hc11.c, dv-m68hc11eepr.c, dv-m68hc11sio.c,
 707         dv-m68hc11tim.c, dv-pram.c: New files representing devices for
 708         68HC11 (dv-pram.c is generic and could probably migrate to common).
 709         * emulos.c: New file, basic emulation of some os.
