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.

bit shift instructions. Correct sign extension for arithmetic
shifts to not shift the number of bits in the type.

instruction.
|

* 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.

getopt1.o, rather than on gencode.c. Link objects together.
Don't link against -liberty.
(gencode.o, getopt.o, getopt1.o): New targets.
* gencode.c: Include <ctype.h> and "ansidecl.h".
(AND): Undefine after including "ansidecl.h".
(ULONG_MAX): Define if not defined.
(OP_*): Don't define macros; now defined in opcode/mips.h.
(main): Call my_strtoul rather than strtoul.
(my_strtoul): New static function.

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.
|
|
* configure.in: Define @SIMCONF@ depending on mips target.
* configure: Rebuild.
* Makefile.in (run): Add @SIMCONF@ to control simulator
construction.
* gencode.c: Change LOADDRMASK to 64bit memory model only.
* interp.c: Remove some debugging, provide more detailed error
messages, update memory accesses to use LOADDRMASK.
|
|
* gencode.c (process_instructions): Ensure FP ABS instruction
recognised.
* interp.c (AbsoluteValue): Add routine. Also provide simple PMON
system call support.
|
|
* interp.c, gencode.c: Some more (TODO) tidying.
|
|
* 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.

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.

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.
