Also, added driver data struct and save states to laserbas.c, laserbat.c, lastfght.c, lazercmd.c and lemmings.c
Finally, added driver data struct to lasso.c
* Fixed EIP displacement when executing FPU instructions with no 80387 present
* Added 32-bit implementations of SLDT and STR

Subject: More i386 fixes
To: submit@mamedev.org
Hi,
Here's two more small fixes for the i386 core.
First, is FPU instructions used on 80386. On a system without a
80387, FPU instructions should have no effect. Part of the FM Towns
TBIOS (runs as an MS-DOS device driver, providing extra system
functions) initialises the FPU, and tries to detect it. Upon hitting
the FSTCW instruction, though, it doesn't increase EIP enough when an
extra displacement byte is needed. So, I've added a call to GetEA to
the escape() function (called when there is no FPU) which will fetch
the extra byte if necessary.
Second, is a 32-bit implementation of the SLDT and STR instructions.
Basically, I copied it from the 16-bit versions, and modified it to
use 32-bit registers.
Thanks,
Barry Rodewald

part. Some shared systems still exist with globals, but this
tackles the atarigen module and the variables local to each
driver.
Also added validity check that AM_BASE_MEMBER and AM_SIZE_MEMBER
items point within the bounds of the driver_data structure.
Added driver data struct to jackal.c
out of the whatsnew, a couple of remarks:
- rallyx and nrallyx might require a separate driver data struct to deal with namco_soundregs, but I'll take care of this eventually (if really needed)
- jackal does not properly save the work ram banks atm, hence no SUPPORTS_SAVE flag, but I keep looking for a clean solution to the problem
Added driver data struct to pipedrm.c and added devices to gameplan.c driver data struct (to remove a few cputag calls)
Also, removed a couple of memory_set_bankptr that I had forgotten (buggychl.c & homedata.c)

Hi mamedev,
This patch improves the quality of the mame driver headers, by adding
missing prototypes and source comments, removing dead prototypes, and
marking some non-exported functions as static within the drivers. It
also eliminates about a dozen cases of #include "deprecat.h".

To: submit@mamedev.org
Cc: atariace@hotmail.com
Hi mamedev,
My srcclean changes to track C-style quotes didn't handle all the
special cases correctly (for instance, '\"' and "\\\""). This fixes
it, and adds some /* ... */ to m68k_in.c so that src2html.exe does a
better job on it.

memory_install_ram() to assign a un-named bank to a region and specify
a pointer to where the RAM lives. If this is called in the DRIVER_INIT
function or MACHINE/SOUND/VIDEO_START functions, then it is permissible
to specify NULL, in which case the memory system will allocate memory
and register it for save states.
memory_install_rom() is like the above except that it only installs a
read handler.
memory_install_writeonly() is like the above except that it only installs
a write handler.
Updated several instances in the code that were assigning banks to these
sorts of static RAM regions and simplified the code.
Also fixed several regressions reported by Tafoid.
