Jeff Law 8824fb459b * simops.c (OP_10007E0): Handle SYS_times and SYS_gettimeofday. 
Check it into devo too.

Jeff Law c500c07496 * simops.c: Include <sys/stat.h>. 
(OP_10007E0): Handle SYS_stat.
For RW testing.

Jeff Law f009978996 * simops.c (OP_500): Mask off low bit in displacement 
for sld.w.
        (OP_501): Similarly.
More bugs exposed by tda testing.

Jeff Law 85c09b0518 * simops.c (OP_500): Fix displacement handling for sld.w. 
(OP_501): Similarly for sst.w.
More fixes exposed by tda testing.

Jeff Law 0a89af6efd * simops.c (trace_input): Remove all references to SEXT7. 
(OP_300, OP_400, OP_500, OP_380, OP_480, OP_501): Displacement
        is zero extended for sst/sld instructions.
        * v850_sim.h (SEX7): Delete.  It's no longer needed (and it
        was incorrect anyway).
So we properly simulate sst/sld instructions.

Stu Grossman 968519095a * Makefile.in: Get rid of srcroot. Set all INSTALL macros via 
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.  (Why is this here in the first place?!?)
	* v850_sim.h:  Get rid of 64 bit defs.  Also, get rid of #elif's.
	Change number of operands in struct simops from 9 to 6.  Define
	SIGTRAP and SIGQUIT for MSVC.
