autoconf. * gencode.c (write_opcodes): Pad operands field to account for MSVC braindamage. * simops.c: Include errno.h. Exclude SYS_chown, since MSVC doesn't support it.

1996-10-15 * interp.c (MEM_SIZE): It's now bytes, not a power of 2.Stu Grossman1-0/+31
* (map): Add support for external mem in the 1->2 meg range. Also, abort() when memory access is way out of bounds. (Better to die than to give wrong result. (This will be fixed later.)) * (sim_size): MEM_SIZE is now bytes, not shift factor.

1996-09-10 * interp.c (hash): Make this an inline functionJeff Law3-44/+43
when compiling with GCC. Simplify. * simpos.c: Explicitly include "sys/syscall.h". Remove some #if 0'd code. Enable more emulated syscalls. Checking in more stuff.
1996-09-03 * gencode.c: Fix various indention & style problems.Jeff Law3-83/+70
Remove test code. Remove #if 0 code. * interp.c: Provide prototypes for all static functions. Fix minor indention problems. (sim_open, sim_resume): Remove unused variables. (sim_read): Return type is "int". * simops.c: Remove unused variables. (divh): Make result of divide-by-zero zero. (setf): Initialize result to keep compiler quiet. (sar instructions): These just clear the overflow bit. * v850_sim.h: Provide prototypes for put_byte, put_half and put_word. Cleaning up.

1996-09-03 * interp.c: OP should be an array of 32bit operands!Jeff Law4-78/+248
(v850_callback): Declare. (do_format_5): Fix extraction of OP[0]. (sim_size): Remove debugging printf. (sim_set_callbacks): Do something useful. (sim_stop_reason): Gross hacks to get c-torture running. * simops.c: Simplify code for computing targets of bCC insns. Invert 's' bit if 'ov' bit is set for some instructions. Fix 'cy' bit handling for numerous instructions. Make the simulator stop when a halt instruction is encountered. Very crude support for emulated syscalls (trap 0). * v850_sim.h: Include "callback.h" and declare v850_callback. Items in the operand array are 32bits. Fixes & syscall stuff.
