Mon Sep 9 13:27:26 1996 Michael Meissner <meissner@tiktok.cygnus.com>
* simops.c (trace_output): Properly align accumulator output.
(OP_3{0,2,4}00): Properly parenthesize test expression. Add error
if shift count is too high.
(OP_4E{00,02,04,20,22,40,42}): Make tests agree with book.
(OP_4E09): Make cpfg properly trace the input flags.
(op_types): Add OP_FLAG_OUTPUT.
(trace_{input,output}): Support OP_FLAG_OUTPUT.
(OP_31000000): This ld2w varient is a 16-bit memory reference, not
an 8-bit memory reference instruction for tracing purposes.
(OP_201): Addi needs to set the carry.
Fri Sep 6 17:56:17 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
* simops.c (OP_2600, OP_2601): Changed min and max comparisons
to use signed register values.
Wed Sep 4 11:35:17 1996 Michael Meissner <meissner@tiktok.cygnus.com>
* d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
output.
(_ins_type): New enumeration to specify which container an
instruction is in, and whether it is part of a parallel operation.
(_state): Add ins_type field.
({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
(ins_type_counters): Counters for the various instruction types.
({left,right}_nops): Counters for the number of nops in each
container.
(d10v_debug): New variable to indicate whether debugging is turned
on.
* simops.c: (all functions): Change all #ifdef DEBUG code so that
the input and output values can be traced, along with the
instruction type. Make the -t option enable tracing.
(all functions): Change printf calls to use the printf_filtered
function in the callback table.
* interp.c (_leftright): New enumeration to say whether 2 short
instructions are done left first or right first.
(do_{long,2_short,parallel}): Indicate in the machine state which
type of instruction this is. Count each of the types of
instructions executed.
(sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
flag is set.
(sim_resume): Pass left/right indication to do_2_short.
(all functions): Change printf calls to use the printf_filtered
function in the callback table.
(sim_trace): Turn on debug flag if DEBUG was defined, and call
sim_resume.
(sim_info): Print out statistics on instructions.
(sim_{trace,create_inferior}): Eliminate extraneous output unless
debugging.
(sim_open): If args == -t and DEBUG was defined, set d10v_debug.
Only initialize the hash table the first time sim_open is called.
* Makefile.in: Make objects depend on d10v_sim.h.
({,SIM_}CFLAGS): Include configure dependent switches. Setting
CFLAGS does not override host/target defines or SIM_CFLAGS.
(CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
(run): By default, the math library is not needed to be linked
in.
({BFD,LIBIBERTY}_LIB): Define as variables so they can be
overridden.
(VPATH): Don't set to anything but @srcdir@ to work with non-GNU
makes.
({run,callback}.o): Provide explicit paths to their appropriate
source directories.
(gencode{,.o},d10v-opc.o): Split compilation into creating object
and linking. Instead of linking in libopcodes.a, just compile
d10v-opc.o directly to handle canadian cross.
(CSEARCH): Add opcodes directory.
* configure.in (--enable-sim-cflags): New switch to allow user to
set the defaults.
(CC_FOR_BUILD): Deal with canadian crosses.
* configure: Regenerate.
Wed Sep 04 04:45:34 1996 Mark Alexander <marka@cygnus.com>
* simops.c: Include correct syscall.h for d10v, not host's.
Fix #ifdef SYS_stat.
Tue Sep 3 14:00:04 1996 Michael Meissner <meissner@tiktok.cygnus.com>
* simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
Add trap 2 to be printf and trap 3 to be putchar.
Wed Aug 28 21:42:34 1996 Mark Alexander <marka@cygnus.com>
* Makefile.in, d10v_sim.h, interp.c, simops.c: Add support
for low-level system calls.
Wed Aug 28 17:33:19 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
* Makefile.in, d10v_sim.h, interp.c: Fix byte-order problems.
Mon Aug 26 18:30:28 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
* d10v_sim.h (SEXT32): Added.
* interp.c: Commented out printfs.
* simops.c: Fixed error in sb and st2w.
Thu Aug 15 13:30:03 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
* Makefile.in, d10v_sim.h, interp.c, simops.c: Added remaining
DSP instructions. Added modulo addressing.
Sun Aug 11 12:57:15 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
* Makefile.in, d10v_sim.h, interp.c, simops.c: Snapshot.
Fri Aug 2 17:44:24 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
* d10v_sim.h, simops.c: Snapshot.
Thu Aug 1 17:05:24 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
* ChangeLog, Makefile.in, configure, configure.in, d10v_sim.h,
gencode.c, interp.c, simops.c: Created.
