Hello everyone,

I just made a new CVS snapshot available for download on
http://www.sourceforge.net/projects/es40.

This fixes a couple of issues with the previous snapshot, and some older bugs.

Camiel.

Changes from last snapshot build:

 - Fixed registration of ROM expansion address. (06-feb-2008, Camiel
   Vanderhoeven)
 - Check for FPEN in old floating point code. (06-feb-2008, Camiel
   Vanderhoeven)
 - Proper interrupt handling in serial port device. Fixes an
   initialization bug spotted by David Hittner. (06-feb-2008, Camiel
   Vanderhoeven)
 - Disable unaligned access check alltogether; it doesn't work properly
   for some reason. (05-feb-2008, Camiel Vanderhoeven)
 - The new floating point code (21-jan-2008) has some unidentified
   problems. The OpenVMS installation routine fails with this new code.
   For now, the old floating point code has been restored, and the new
   floating-point code is used only when HAVE_NEW_FP has been defined.
   The new code should be fixed, so we can take advantage of floating
   point exceptions. (05-feb-2008, Camiel Vanderhoeven)
 - Display a message when system initialization has failed. (05-feb-2008,
   Brian Wheeler)
 - Put X64 around 64-bit constants in DO_CVTQL. (compilation issue on some
   Linux'es) (05-feb-2008, Camiel Vanderhoeven)
 - Corrected a typo in the definition of PCI_PTE_SHIFT (2 should be 12)
   that caused an OpenVMS procgone bugcheck. (04-feb-2008, Camiel
   Vanderhoeven)

Changes from version 0.17:

 - Completed LPT support so it works with FreeBSD as a guest OS.
   (02-feb-2008, Brian Wheeler)
 - Avoid unnecessary shift-operations to calculate constant values.
   (01-feb-2008, Camiel Vanderhoeven)
 - Improved speed by remembering the number of instructions left in current
   memory page, so that the translation-buffer doens't need to be consulted
   on every instruction fetch when the Icache is disabled. (30-jan-2008,
   Camiel Vanderhoeven)
 - Remember separate last found translation-buffer entries for read and write
   operations. This should help with memory copy operations. (29-jan-2008,
   Camiel Vanderhoeven)
 - Avoid interrupts from the new IDE device that originated while interrupts
   were disabled. (29-jan-2008, Brian Wheeler)
 - Improved floating-point exception handling. (28-jan-2008, Camiel
   Vanderhoeven)
 - Lifted hardcoded file-size limit of 10,000 bytes for config file.
   (26-jan-2008, Camiel Vanderhoeven)
 - Bugfix in the VAX floating point STF and the IEEE floating point STS
   instructions. (26-jan-2008, Camiel Vanderhoeven)
 - Don't repeat interrupts from the new IDE controller too soon.
   (26-jan-2008, Brian Wheeler)
 - Do unaligned trap only when a page boundary is crossed. Something is
   causing alignment traps in the SRM console, with the DAT bit set to false,
   and no OS handler in place. Also, when OpenVMS boots there are alignment
   traps that shouldn't happen. None of these cross page boundaries, so we're
   safe for now. (26-jan-2008, Camiel Vanderhoeven)
 - Trap on unaligned memory access. The previous implementation where
   unaligned accesses were silently allowed could go wrong when page
   boundaries are crossed. (25-jan-2008, Camiel Vanderhoeven)
 - Allow specifying autocreate_size on a disk image to have it created if it
   doesn't exist. (25-jan-2008, Camiel Vanderhoeven)
 - Added an option to disable the processor Icache. The emulator runs faster
   when this is disabled, but that might lead to problems with some OS'es.
   (25-jan-2008, Camiel Vanderhoeven)
 - Added do_pci_write and do_pci_read functions to the PCI base device.
   (24-jan-2008, Camiel Vanderhoeven, David Hittner)
 - Fixed overflow-detection. (24-jan-2008, Camiel Vanderhoeven)
 - Added missing integer /V instructions (22-jan-2008, Camiel Vanderhoeven,
   Bob Supnik)
 - win32 GUI made compatible with older windows SDK. (22-jan-2008, Camiel
   Vanderhoeven)
 - New floating-point code (21-jan-2008, Camiel Vanderhoeven, Bob Supnik)
 - Fixed misinterpretation of the INT bit in integer overflow traps. (Camiel
   Vanderhoeven, 21-jan-2008)
 - Limited the maximum number of sectors, as the OpenVMS IDE driver doesn't
   like 255 sectors. (Camiel Vanderhoeven, 21-jan-2008)
 - Added X11 GUI. (20-jan-2008, Camiel Vanderhoeven)
 - Added win32 GUI. (19-jan-2008, Camiel Vanderhoeven)
 - Run CPU in a separate thread if CPU_THREADS is defined. NOTA BENE: This is
   very experimental, and has several problems. (19-jan-2008, Camiel
   Vanderhoeven)
 - Replaced sext_64 inlines for performance reasons (18-jan-2008, Camiel
   Vanderhoeven, David Hittner)
 - Process device interrupts after a 100-cpu-cycle delay. (18-jan-2008,
   Camiel Vanderhoeven)
 - Added ADDL/V instruction (16-jan-2008, David Hittner, Bob Supnik)
 - Fixed some timeouts on new IDE controller. (16-jan-2008, Brian Wheeler)
 - When a keyboard self-test command is received, and the queue is not empty,
   the queue is cleared so the 0x55 that's sent back will be the first thing
   in line. Makes the keyboard initialize a little better with SRM.
   (15-jan-2008, Brian Wheeler)
 - Bugfix regarding double deletion of disk device objects. (13-jan-2008,
   Brian Wheeler)
 - New IDE-controller working on big-endian host architectures. (13-jan-2008,
   Fang Zhe)
 - Support additional CD-ROM commands. (13-jan-2008, Brian Wheeler)
 - Smart algorithm for determining optimal cylinder/head/sector disk layout.
   (13-jan-2008, Camiel Vanderhoeven)
 - End debugger run on Ctrl-C. (12-jan-2008, Brian Wheeler)
 - SCSI Engine added to Disk class. SCSIBus class and SCSIDevice base class
   added. (12-jan-2008, Camiel Vanderhoeven)
 - bugfix to ATAPI code in new IDE controller. SRM can now boot from IDE
   CD-ROMs. (09-jan-2008, Brian wheeler)
 - ATAPI improvements to new IDE controller. (09-jan-2008, Brian wheeler)
 - Put filename without path in disk model number. (09-jan-2008, Brian
   Wheeler)
 - Save disk state to state file. (09-jan-2008, Camiel Vanderhoeven)
 - Use Brian Wheeler's CNewIde class instead of the CAliM1543C_ide class if
   HAVE_NEW_IDE is defined. This change will be undone when the new ide
   controller will replace the old standard one. (08-jan-2008, Camiel
   Vanderhoeven)
 - "Old" IDE-controller working on big-endian host architectures.
   (08-jan-2008, Fang Zhe)
 - S3 Trio VGA-card working on big-endian host architectures. (08-jan-2008,
   Fang Zhe)
 - Removed last references to IDE disk read SRM replacement. (08-jan-2008,
   Camiel Vanderhoeven)
 - Added NewIde class. Due to replace the current IDE controller
   implementation. (08-jan-2008, Brian Wheeler)
 - PCI scatter/gather DMA memory mapping support added. (07-jan-2008, Camiel
   Vanderhoeven)
 - Default blocksize set to 2048 bytes for CD-ROM devices. (06-jan-2008,
   Camiel Vanderhoeven)
 - Allow changing block-size on disk devices. (06-jan-2008, Camiel
   Vanderhoeven)
 - Fixed typo in network-code (05-jan-2008, Fausto Saporito)
 - Do 64-bit file I/O properly for FreeBSD and OS X. (05-jan-2008, Fang Zhe)

   Vanderhoeven)
