 	support for Sun hosts.
	* Makefile.in (gencode): Ensure the host compiler and libraries
 	used for cross-hosted build.

* 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.

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.
1995-12-01 16:42:44 +00:00
Jackie Smith Cashion
8ad5773724 Initial check-in of the MIPS simulator. Work still needs to be done on
the run-time support code (interp.c) to provide better tracing, and
also to add profiling and architecture specific support. At the moment
the simulator has a fixed size, fixed address memory area, and
simulates a subset of the IDT monitor calls (enough to execute test
programs).

The other major feature (could even be a bug) is that the simulator
makes use of the GCC "long long" extension. Work has been started to
make this a build configuration option... but there is still a lot of
this to be done.
