binutils-gdb/sim/d10v/ChangeLog
Andrew Cagney 70ee56c585 Rework sim/common/sim-alu.h to differentiate between direcct 
subtraction (involves borrow) and negated addition (involves carry).
Update d30v so that it uses this method.  Add more tests.

(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.

* 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.
