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.
instead of `long long' and `unsigned long long' data types.
* interp.c: #include sysdep.h to get signals, and define default
for SIGBUS.
* (Convert): Work around for Visual-C++ compiler bug with type
conversion.
* support.h: Make things compile under Visual-C++ by using
__int64 instead of `long long'. Change many refs to long long
into word64/uword64 typedefs.
* 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.
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.
