50d45d1b2f * compile.c (sim_resume): Fix overflow checks for ALU insns. 
So that int-compare.c passes.

* configure.in: Use AC_CHECK_TOOL to find AR & RANLIB.
	* configure: Regenerate using autoconf.

e24146ec95 * compile.c (decode): Use "bit" to hold L_3 immediates instead 
of holding them in "abs".  Handle ABS8MEM memory references aka
        8-bit area.  Replace ABSMOV references with ABS8MEM.
So we've got a chance of simulating something like btst #0,@40:8 correctly.
hmse.

* interp.c (Convert): Provide round-to-nearest and round-to-zero
 	support for Sun hosts.
	* Makefile.in (gencode): Ensure the host compiler and libraries
 	used for cross-hosted build.

Allow a DOS hosted version of the simulator to be built. NOTE: The FP
is still not complete, since round-to-nearest and round-to-zero have
not been implemented generically.

a647a859cb Thu Mar 7 11:19:33 1996 James G. Smith <jsmith@cygnus.co.uk> 
* gencode.c, interp.c: Replaced explicit long long references with
 	WORD64HI, WORD64LO, SET64HI and SET64LO macro calls.
	* support.h (SET64LO, SET64HI): Macros added.

This is an intermediate checkin. The work of removing "long long"
usage is not yet finished. These changes are clean, and have been
sitting on my machine for a while (whilst doing other work), and it is
safer for them to be checked in.

2434e38489 * gencode.c (tab): Added several sh3 opcodes. 
(think): Added printonmatch for A_SSR and A_SPC.
* interp.c (SSR, SPC): Added definitions.
(saved_state_type): Added ssr and spc registers.

8bae0a0c48 * gencode.c: Tidied instruction decoding, and added FP instruction 
support.
* interp.c: Added dineroIII, and BSD profiling support. Also
run-time FP handling.

At the moment the options are still mostly build-time controlled,
rather than run-time. Also work still needs to be done to remove (long
long) usage (However this is trivial, just time-consuming).

The out-standing instruction work to be done is in supporting round
and trunc for FP operations, and providing better exception support.

9dfb65e661 * gencode.c (tab): In shad/shld definitions, negate R[m] before 
the and operation instead of after.  For shad delete cast.  For shld
	use UR instead of R and delete cast.
