and patterns.
* interp.c (sim_resume): Save and restore PC from the appropriate
register.
* (sim_fetch_register sim_store_register): Fix byte-order problem
with reading and writing registers.
* simops.c (OP_FFFF): Implement pseudo-breakpoint insn.
* interp.c (SignalException): Check for explicit terminating
breakpoint value.
* gencode.c: Pass instruction value through SignalException()
calls for Trap, Breakpoint and Syscall.
* interp.c (SquareRoot): Add HAVE_SQRT check to ensure sqrt() is
only used on those hosts that provide it.
* configure.in: Add sqrt() to list of functions to be checked for.
* config.in: Re-generated.
* configure: Re-generated.
expanding STORE RIGHT, to fix swr.
* support.h (SIGNEXTEND): If the sign bit is not set, explicitly
clear the high bits.
* interp.c (Convert): Fix fmt_single to fmt_long to not truncate.
Fix float to int conversions to produce signed values.
* run.c (main): Explicitly cast malloc() parameter.
This is needed because for certain builds the size field being given
to malloc() is actually 64bits long, and without a cast or malloc
prototype the resulting value used by malloc() depended on the host
endianness, and how long long paramaters are passed into functions.
* interp.c (sim_monitor): Improved monitor printf
simulation. Tidied up simulator warnings, and added "--log" option
for directing warning message output.
* gencode.c: Use sim_warning() rather than WARNING macro.
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.
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.
