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