2008-03-27 Bart
* [r1853] ChangeLog, NEWS:
DOSEMU 1.4.0.1
* [r1852] configure, configure.ac, src/commands/Makefile,
src/plugin/commands/Makefile:
Fix 64-bit compilation on 32-bit systems and vice versa.
* [r1851] src/base/bios/hlt.c, src/dosext/mfs/mfs.c,
src/plugin/kbd_unicode/keyb_raw.c:
Fix more gcc warnings for 64-bit compilation.
* [r1850] src/base/bios/int10.c, src/plugin/term/terminal.c:
Cleaner fix for terminal memory map race.
2008-03-26 Bart
* [r1849] VERSION:
DOSEMU 1.4.0.1
* [r1848] Makefile:
Remove configure.lineno on distclean.
* [r1847] src/base/init/lexer.l.in:
Avoid gcc-4.3 warning about unused input function in lexer.
* [r1846] src/base/bios/int10.c, src/plugin/term/terminal.c:
Add a call to video->update_screen to int10/ah=0 modesets to make
sure the terminal is initialized. Fixes a race (though it should be
done more cleanly).
2008-03-25 Bart
* [r1845] src/arch/linux/dosext/sound/midid/timid.c,
src/plugin/midimisc/mid_o_tmdty.c:
In timidity plugin and midid code: use socketpair as a bidirectional
pipe: older versions (current as of 2008 :( ) of timidity write to
stdin and we can catch that to avoid waiting 3 seconds at select at
DOSEMU startup.
2008-03-21 Bart
* [r1844] src/dosext/mfs/lfn.c:
Add missing "return" for LFN findnext error. Fixes #1801411: Running
File Wizard crashes DOSEMU 1.4.0.0.
* [r1843] src/plugin/term/keyb_slang.c, src/plugin/term/terminal.c:
Added some diagnostics to check for UTF-8 terminal mismatches;
"fixes" bug #1729556.
2008-03-18 Bart
* [r1842] src/emu-i386/simx86/trees.c:
Try to fix #1910153 again: we need to round to PAGE_SIZE for the loop
termination test because of backwards jumps and NOJUMPS.
* [r1841] src/emu-i386/simx86/codegen-sim.c:
SF-Patch #1683073: handle 16bit address overflow in string
instructions. Fixes overflow in the simulator of cpu-emu. Adjusted
from Michael Karcher's patch.
2008-03-17 Bart
* [r1840] src/emu-i386/simx86/trees.c:
Bail out of node-to-invalidate check loop for the sorted list once
the base (instead of the PC-beginning of the block) is past the
affected address. Really fixes #1910153: SkyRoads failure: JIT fails
some self-modifying code (Michael Karcher).
2008-03-16 Bart
* [r1839] src/emu-i386/simx86/trees.h:
Fix #1910153 SkyRoads failure: JIT fails some self-modifying code.
The dnpc field needs to be signed because it can be negative and is
compared to negative "int"s in BreakNode.
2008-03-11 Bart
* [r1838] src/emu-i386/simx86/sigsegv.c:
Patch #1910535, Michael Karcher: fix for "e_vgaemu_fault corrupts
eip/rip"
* [r1837] src/env/video/vgaemu.c:
In Super-VGA modes, do *not* wrap memory at 256k. SF patch #1910415,
Michael Karcher; fixes bug #1806787.
2008-02-18 Stas
* [r1836] src/base/dev/dma/dmanew.c, src/base/dev/sb16/sb16.c:
OK, the good-bye cannot be that rude any more. My apologies to the
sound.c authors for that silly remark of mine and I hope you can do a
good work on my code.
2007-12-06 Bart
* [r1835] src/arch/linux/async/sigsegv.c:
Use fpregset_t instead of _fpstate to avoid problems with Debian's
glibc for x86_64.
2007-09-24 Bart
* [r1834] src/emu-i386/simx86/codegen-sim.h,
src/emu-i386/simx86/codegen-x86.h:
Replace BT24 and BTA inline asm by C.
2007-09-23 Bart
* [r1833] src/emu-i386/simx86/interp.c:
Michael Karcher: #1800717 cpuemu: BOUND is signed. The current bound
implementation does a signed compare instead of an unsigned one. This
patch should fix it.
* [r1832] src/base/async/int.c, src/base/dev/misc/lpt.c,
src/emu-i386/simx86/interp.c:
Implement the bound instruction (albeit fully interpreted). Make sure
that int 5 does not try printscreen if there is no printer.
* [r1831] src/emu-i386/simx86/interp.c:
From Michael Karcher: #1763170 CPU emu: implement INTO correctly. The
INTO instruction should generate the overflow execption only if the
overflow flag is set, not on every invocation.
* [r1830] src/emu-i386/simx86/interp.c:
From Michael Karcher: SF #1763169 CPU emu: handle prefixed jumps
correctly: The distance in a (not 8-bit) jump instruction is encoded
according to operand size, not address size. There is some wrong
documentation in this regard, even the processor reference manual I
usually use. The size of CX used in JCXZ is depending on the address
size, as correctly implemented in dosemu.
* [r1829] src/emu-i386/simx86/interp.c:
From Michael Karcher, #1763166 CPU emu: ignore access to unknown VGA
ports Currently, dosemu crashes on read/write access to unhandled
ports in the VGA range when cpuemu is enabled. While this is
acceptable behaviour while developing, it is not helpful for the end
user, who has a program probing for different SVGA cards by direct
hardware access.
2007-06-11 Bart
* [r1828] src/dosext/mfs/lfn.c, src/tools/Makefile:
Fixed some warnings with 64-bit builds.
2007-06-05 Bart
* [r1827] etc/global.conf, src/plugin/X/X.c:
Fix $_X_winsize; also enable to use it, and X_aspect_43 with text
modes with bitmapped fonts.
2007-06-04 Bart
* [r1826] src/dosext/dpmi/msdos.c:
Add DPMI API translation support for int21/ax=71a6.
* [r1825] src/base/async/int.c, src/dosext/mfs/lfn.c,
src/dosext/mfs/mfs.c, src/dosext/mfs/mfs.h, src/include/dos2linux.h:
Implement the LFN handle functions int21/ax=5704,5,6,7, and 71a6.
Also avoid using the set attribute ioctl on non-FAT filesystems.
2007-06-03 Bart
* [r1824] dist/dosemu:
Correct dosemu script.
* [r1823] src/plugin/sdl/sdl.c:
Fix SDL video mode chooser if only one mode is available.
* [r1822] src/plugin/X/X.c:
Fix "dosemu -w" for X and error messages for $DISPLAY not set.
* [r1821] src/plugin/kbd_unicode/keymaps.c, src/plugin/term/terminal.c:
Prompt if the keyboard layout can't be auto-detected. Initialize the
SLang terminal screen draw routines as late as possible (the first
time something needs to be drawn) so that other error messages can
still be seen on the normal (non-SLang) terminal screen.
* [r1820] dist/dosemu, dist/dosemu.bindist, dist/dosemu.systemwide,
man/dosemu.bin.1.in, src/arch/linux/Makefile.main,
src/base/init/config.c, src/include/emu.h, src/plugin/X/X.c,
src/plugin/X/X_font.c, src/plugin/term/terminal.c:
Move xset functionality to obtain the X fonts and the terminal < 25
lines warnings from dosemu to dosemu.bin.
2007-06-01 Bart
* [r1819] src/base/async/int.c, src/base/bios/int10.c,

src/emu-i386/simx86/cpu-emu.c, src/include/Asm/vm86.h,
src/include/machcompat.h:
Change longs in vm86.h to ints to be consistent between x86-64 and
i386.
* [r1818] src/base/bios/int10.c, src/env/video/crtcemu.c,
src/env/video/seqemu.c, src/env/video/vgaemu.c:
Fix VESA text modes (fixes SR#1728817).
2007-05-30 Bart
* [r1817] src/plugin/commands/generic.S:
Fix preprocessor confusion.
2007-05-28 Bart
* [r1816] src/base/async/int.c, src/base/misc/dos2linux.c,
src/dosext/mfs/mangle.h, src/dosext/mfs/util.c,
src/include/dos2linux.h, src/plugin/X/X.c, src/plugin/sdl/sdl.c,
src/plugin/term/terminal.c, src/plugin/translate/include/translate.h,
src/plugin/translate/translate.c:
Better fix for X window titles & UTF-8. The title is now passed to
the plugin using a wchar_t string.
2007-05-25 Bart
* [r1815] src/dosext/mfs/lfn.c, src/dosext/mfs/mfs.c,
src/dosext/mfs/mfs.h:
Let find_file report FILE_NOT_FOUND or PATH_NOT_FOUND in an extra
parameter depending on whether the directory where the file to be
searched would be in exists or not.
2007-05-23 Bart
* [r1814] src/base/init/parser.y.in, src/dosext/mfs/mfs.c,
src/env/video/vgaemu.c:
Fix a memory leak and some other issues found by Valgrind.
2007-05-21 Bart
* [r1813] src/emu-i386/simx86/sigsegv.c:
CPUEMU: do not mix up LDT accesses with emulator page faults, and
translate non-zero based DPMI addresses to the correct pointer.
2007-05-18 Bart
* [r1812] etc/global.conf, src/base/init/lexer.l.in,
src/base/init/parser.y.in, src/env/video/vesa.c, src/include/emu.h:
Use vgaemubios_file internally to get the Bochs BIOS to avoid mixing
up with using it with console graphics, and be able to run it in a
non-root console.
* [r1811] src/doc/README/config, src/plugin/X/screen.c,
src/plugin/kbd_unicode/include/keyb_clients.h,
src/plugin/kbd_unicode/keyb_clients.c,
src/plugin/translate/config/plugin_parser,
src/plugin/translate/include/translate.h,
src/plugin/translate/translate_config.c:
Improve pasting in X into DOSEMU too, trying to ask for UTF-8, then
iso2022, and then iso8859-1. This obsoletes the use of
$_external_char_set for pasting.
* [r1810] src/base/async/int.c:
Add forgotten init memset of mbstate_t unix_state to 0. Fixes crash
on x86-64.
* [r1809] src/env/video/text.c, src/include/vgatext.h,
src/plugin/X/screen.c:
Improving pasting text from DOSEMU: follow guidelines about which
character sets to use (in practise we must usually convert to UTF8
nowadays).
* [r1808] src/plugin/kbd_unicode/keyb_clients.c:
Check for -1 return from character_count (if an invalid multibyte
character string is pasted for example), so DOSEMU won't crash.
* [r1807] src/base/bios/int10.c:
Add missing semicolon in int10.c
* [r1806] src/arch/linux/debugger/mhpdbgc.c, src/base/async/int.c,
src/base/misc/disks.c, src/base/misc/fatfs.c,

src/plugin/commands/dosdbg.c, src/plugin/commands/lredir.c,
src/plugin/commands/msetenv.c, src/plugin/commands/xmode.c:
Force within-ASCII uppercasing for ASCII letters for toupperDOS and
friends. Consistently use toupperDOS etc. functions instead of
toupper etc. to avoid problems with the dotless i as used in Turkish
and some other languages. In fatfs.c convert from the Linux to the
DOS character set, and vice versa for the X title display.
2007-05-17 Bart
* [r1805] src/base/bios/bios.S:
Always covert ax=6cxx to 6c00 for the int21/ah=6c LFN->DOS converter.
2007-05-16 Bart
* [r1804] src/env/video/vesa.c:
Allow larger Bochs vgabios'es to be used than 32K.
2007-05-14 Bart
* [r1803] src/emu-i386/simx86/interp.c:
Implemented lock prefix (either ignored, or illegal op).
2007-05-13 Bart
* [r1802] src/emu-i386/simx86/cpu-emu.c:
SIMX86: Don't try to stretch time using RDTSC if $_rdtsc=(off)
* [r1801] src/emu-i386/simx86/cpu-emu.c, src/emu-i386/simx86/interp.c:
Push IOPL_MASK on the stack for pushf and int. Fixes vm86 mode
detection of DOS4GW when $_dpmi=(off).
* [r1800] src/arch/linux/async/signal.c:
Revert DPMI-inability detection change from #1799.
* [r1799] src/arch/linux/async/signal.c,
src/arch/linux/async/sigsegv.c, src/dosext/dpmi/dpmi.c,
src/dosext/dpmi/dpmi.h, src/emu-i386/simx86/sigsegv.c,
src/env/video/vgaemu.c:
When handling signals, check for a valid DPMI selector, which means
that it is an LDT selector and not reserved by glibc or similar, e.g.
for pthreads. Else, and that includes the whole GDT, assume we
interrupt DOSEMU code. SystemSelector() in DPMI now refers to
anything not covered by the above, plus dpmi_sel16 & dpmi_sel32. This
fixes crashes with Xen-DOM0 on x86-64 where cs is 0x33 on entry to
signal handlers but set to 0xe033 after the first syscall.
2007-05-11 Bart
* [r1798] src/emu-i386/simx86/interp.c:
Remove (replace by an e_printf) debug code that aborts CPUEMU if 4 or
more 0's in a row are executed. Some .com programs do this to skip
over data (Reinhard Karcher).
* [r1797] dist/dosemu, src/emu.c:
Moved DOSDRIVE_D environment manipulation from the dosemu script to
dosemu.bin so it also works with sudo.
* [r1796] src/arch/linux/async/debug.c, src/arch/linux/async/sigsegv.c,
src/base/init/init.c:
Reorganize some debug reporting a bit. uname and the GCC version
number are now always reported in boot.log. Added some bug report
instructions.
* [r1795] src/plugin/X/X.c, src/plugin/sdl/sdl.c,
src/plugin/term/term_core.c:
Fix terminal init problem (no terminal input running xdosemu) if no
dynamically linked plugins are used.
* [r1794] default-configure:
Check the default bitness of gcc, instead of blindly relying on
uname.
* [r1793] src/dosext/dpmi/dpmi.c, src/emu-i386/cpu.c,
src/emu-i386/simx86/sigsegv.c, src/include/emu.h:
Implement some workarounds for the CPU ESP bug. It is unlikely that
it will be worked around in 64-bit kernels. Compare with segment
limits instead of what is supposed to be kernel space (it isn't on
x86-64). Fixes the ancient MS Linker and the Need For Speed demo on
x86-64.
2007-05-10 Bart
* [r1792] src/emu-i386/simx86/sigsegv.c:
Do not patch code that has just tried to overwrite code instead of
data. Fixes a crash with Larry.
2007-05-09 Bart
* [r1791] src/dosext/mfs/mfs.c:
As the read-only attribute is mostly ignored for directories in DOS,
the dos_would_allow check for writable directories doesn't make much
sense. Instead simply check if the file is writable.
* [r1790] src/dosext/mfs/mfs.c:
It is possible to work around the x86-64 FAT compat-ioctl kernel bug.
Thanks to Wine.
2007-05-08 Bart
* [r1789] src/arch/linux/async/signal.c, src/emu.c:
Force $_cpu_emu="full", and do not crash, if %cs is not saved for
signal handlers on x86-64 (kernels < 2.6.15, #1713659).
* [r1788] src/arch/linux/dosext/sound/midid/oss.c,
src/arch/linux/dosext/sound/midid/timid.c,
src/plugin/midimisc/mid_o_oss.c:
Declare *seqbuf_dump static before including soundcard.h. Hopefully
that solves all warnings and errors with the variations out there.
* [r1787] src/plugin/kbd_unicode/keymaps.c:
Do not attempt to load the X plugin if X isn't compiled.
* [r1786] src/dosext/mfs/lfn.c:
int21/ax=7160/cl=1,2 must return an error if the file does not exist.
Fixes problems with FreeCOM mkdir not preserving the LFN directory
name.
* [r1785] src/dosext/mfs/mfs.c:
Ignore attempts to translate the archive and read-only attributes to
Unix permissions for directories. Fixes problem with pkunzip (Joe
Ripley, linux-msdos).
2007-05-07 Bart
* [r1784] dist/autoexec.bat, dist/config.sys, src/base/async/int.c,
src/plugin/commands/blaster.c:
Reduce lines of output in config.sys, autoexec.bat, blaster, and the
banner, so everything fits on 25 lines.
* [r1783] src/dosext/mfs/lfn.c:
Fix more illegal writes in the LFN code (crashed DJGPP gcc with
cpuemu=vm86).
2007-05-06 Bart
* [r1782] Makefile, Makefile.conf.in, src/Makefile.common,
src/arch/linux/Makefile.main, src/commands/Makefile:
Speed up 'make' a bit: - don't use bash anymore; remove bash-isms and
eliminate pwd -P - don't use the intermediate tmp directory for make
install anymore - use -rR make flags to ignore built-ins and made
some built-ins explicit
* [r1781] configure, configure.ac, src/plugin/kbd_unicode/configure,
src/plugin/sdl/configure:
Execute sub-configures by hand to avoid autoconf warnings and
possible future breakage.
* [r1780] Makefile.conf.in, configure, configure.ac, default-configure:
Allow dash to be used as sh in out-of-tree builds.
* [r1779] Makefile.conf.in:
Do not forget sndfile and alsa libraries when building without
dynamically loaded plugins.
* [r1778] src/base/bios/int10.c:
Implement INT10/AH=1c (save/restore video state)
2007-05-05 Bart
* [r1776] ChangeLog, NEWS, dist/config.sys, dist/dosemu.bindist,
dist/mkbindist:
Last minute fix for 1.4.0: fix #1713278 COMSPEC setting wrong. Use
config.sys/autoexec.bat distributed from here in the bindist instead
of the one in dosemu-freedos-*-bin*.
* [r1775] NEWS, ChangeLog:
Release 1.4.0.
* [r1774] INSTALL, README, README.bindist, doc/README.txt,
doc/announce, src/base/init/install.c, src/doc/README/config,
src/doc/README/header:
More documentation updates; added a quick more basic introduction at
the beginning of README.txt.
2007-05-04 Bart

* [r1772] src/dosext/mfs/lfn.c, src/emu-i386/simx86/codegen-sim.c,
src/plugin/commands/lredir.c:
gcc-2.95 compatibility fixes.
* [r1771] src/base/init/config.c, src/emu-i386/ports.c:
Convert error about direct port i/o without root into a warning.
Err about using "-s" without enough privileges.
* [r1770] src/arch/linux/Makefile.main:
Fix man page out-of-tree building.
* [r1769] (almost all files changed)
Update copyright line to 2007.
* [r1768] dosemu.spec.in:
Added missing new directory and symbolic link to dosemu.spec.
* [r1767] src/arch/linux/Makefile.main:
Make man files at "make" instead of "make install" time.
* [r1766] dist/dosemu, dist/dosemu.bindist, dist/mkbindist,
man/dosemu.bin.1.in, src/arch/linux/Makefile.main,
src/base/init/config.c, src/base/init/install.c,
src/base/init/parser.y.in, src/base/misc/fatfs.c:
Allow --Flibdir for suid configurations, as it hasn't been used to
locate global.conf for years. Document the allowance for
--Flibdir/--Fimagedir. Repair bindist/mkbindist to work with the
new FreeDOS configuration. This means using --Flibdir and
$DOSEMU_LIB_DIR instead of the hardcode DOSEMULIB_DEFAULT.
Run mkfontdir at "make" instead of "make install" time when possible.
* [r1765] src/plugin/commands/lredir.c:
Fix lredir c: d:
2007-05-03 Bart
* [r1764] configure, configure.ac, src/plugin/sdl/Makefile:
Fix forgotten make distclean file in SDL plugin; add -lXext for
Xxf86vm checking on certain systems.
* [r1763] INSTALL, configure, configure.ac:
Check for the existence of the Xxf86vm and Xext libraries, not just
header files. Adjust INSTALL instructions.
* [r1762] config.guess, config.sub, configure, configure.ac:
Don't use -mtune by default. It doesn't bear much relation to 'uname
-m' anymore on anything newer than a Pentium Pro.
* [r1761] etc/dosemu.users.example, src/base/init/config.c,
src/base/init/parser.y.in, src/base/misc/priv.c, src/include/priv.h:
Register the difference between sudo and suid-root.
Use c_all as the default for users who run dosemu via sudo so
dosemu.users does not need to be edited for that case, leaving
the default "restricted" (only console graphics at the console,
no remote direct hardware access) setting for suid-root.
2007-05-02 Bart
* [r1760] src/arch/linux/Makefile.main:
Use -rm instead of rm to deal with non-existing directories.
Use bdftopcf at make time instead of make install.
Fixes problems reported at linux-msdos (perry hargrave).
* [r1759] src/base/init/parser.y.in:
Repair $_sound=(on). You would only get the old sound driver via
$_sound=(1).
2007-05-01 Bart
* [r1758] src/env/video/dualmon.c, src/env/video/hgc.c,
src/env/video/matrox.c, src/env/video/vc.c:
Mark all mapped video memory PROT_EXEC, similar to the VGAEMU memory.
Solves a few problems with console video on x86-64.
* [r1757] src/emu-i386/simx86/fp87-x86.c:
Use aliased memory for emulation of FSTENV/FSAVE.
* [r1756] src/emu-i386/simx86/cpatch.c:
There is a slight chance that the CPUEMU cpatch stubs hit VGA memory.
For that case there is a simple instruction decoder but we must use
explicit assembly instructions. Fixes another problem with Norton
SysInfo.
2007-04-30 Bart
* [r1755] src/emu-i386/simx86/codegen-sim.c:
Fix regression in vgaemu handling from #1754.
Fix problem with rep movs with df set backwards for simulated cpuemu
with planar VGA modes.
* [r1754] src/emu-i386/simx86/codegen-sim.c,
src/emu-i386/simx86/sigsegv.c, src/env/video/vgaemu.c:
Fix problems with programs that try to access unmapped VGA memory or
write to ROM in CPUEMU, such as Norton SysInfo.
2007-04-29 Bart
* [r1753] src/dosext/mfs/mfs.c:
Check for FAT filesystem before attempting to use the VFAT ioctls.
Also check if the first entry is ".\0" to avoid an ioctl32 bug in
kernels <= 2.6.21.1.
2007-04-27 Bart
* [r1751] VERSION, NEWS, ChangeLog, doc/DOSEMU-HOWTO.txt,
etc/dosemu.conf:
Regenerate documentation. Release 1.3.5.
* [r1750] src/plugin/commands/lredir.c, src/plugin/commands/msetenv.c:
Avoid CPUEMU problems with msetenv. Only set DOSEMU_LASTREDIR if no
drive letter was given; improve lredir command line processing with C
and R.
* [r1749] etc/dosemu.conf, src/base/dev/misc/lpt.c:
Flush every second when printing. Fix $_lptx="" to not register any
ports.
* [r1748] src/dosext/dpmi/msdos.c:
Fix #1638135 (int 21h, ax=6300 not translated currently, japheth)
* [r1747] src/dosext/mfs/mfs.c, src/dosext/mfs/mfs.h:
Always return . and .. as the first two entries for
findfirst/findnext to be consistent with real DOS. On Linux they
can be somewhere in the middle.
2007-04-26 Bart
* [r1746] src/base/misc/dos2linux.c, src/include/dos2linux.h,
src/plugin/commands/lredir.c, src/plugin/commands/unix.c:
Apply #1691712 make lredir able to automatically choose next free
drive II (Stuart Axon)

Made a note about libXxf86vm (#1644784)
* [r1744] man/dosemu.1.in:
[ 1692149 ] Describe --version in man page (fix for 1245033) (Stuart
Axon)
* [r1743] src/doc/HOWTO/dosemu-HOWTO.sgml:

src/dosext/dpmi/dpmi.h, src/emu-i386/cpu.c, src/include/cpu.h,
src/include/emu.h:
Use fxsave/fxrstor when available on i386 to deal with SSE fp.
Make sure the fxsave buffer is paragraph aligned (fixes a bug with
DJGPP gcc on x86_64).
2007-04-22 Bart
* [r1740] src/dosext/dpmi/dpmi.c:
Check fs/gs values before loading them on x86-64. Preserves 64 bit
segment bases on Intel chips (but apparently makes no difference on
AMD's).
2007-04-20 Bart
* [r1739] src/dosext/dpmi/dpmi.c:
Fix LFB w/console graphics for x86-64.
* [r1738] src/base/async/pci_bios.c, src/base/dev/misc/pci.c,
src/env/video/matrox.c, src/include/pci.h:
Fix PCI support on x86-64.
* [r1737] src/emu-i386/do_vm86.c, src/include/cpu.h:
Use fnsave instead of fsave for saving the FPU state. Should fix
#1436788.
* [r1736] src/plugin/term/keyb_slang.c,
src/plugin/translate/charsets/utf8.c:
Fix problems with utf-8 multibyte input in terminals (reported by
Grigory Batalov, linux-msdos).
2007-03-29 Bart
* [r1735] dist/dosemu, src/base/init/config.c:

2007-03-11 Bart
* [r1726] src/emu-i386/simx86/cpu-emu.c, src/emu-i386/simx86/interp.c:
Use leavedos(1) for EMU86 failure to drop into dosdebug; improve
diagnostics. For rep outs, use not_permitted and let the port code
deal with it instead of quitting DOSEMU.
* [r1725] src/emu-i386/simx86/cpatch.c, src/emu-i386/simx86/trees.c:
Break node if current eip is in a page to be unprotected; fixes bug
#1678581
2007-03-10 Bart
* [r1724] src/dosext/mfs/dosc.c, src/dosext/mfs/lfn.c:

Fix AltGr handling with SDL. It was confused with ScrollLock.
* [r1713] src/plugin/sdl/keyb_SDL.c:
Try to use keysyms where possible in the SDL keyboard code.

2006-11-18 Bart
* [r1710] VERSION, NEWS, ChangeLog, src/doc/DANG/DANG.sgml,
src/doc/README/CDROM, doc/DANG.txt, doc/README.cpuemu,
doc/README.txt, doc/EMUfailure.txt:
Added CDROM lredir documentation. Regenerate documentation.
Release 1.3.4.
* [r1709] src/arch/linux/async/debug.c, src/base/init/lexer.l.in,
src/base/misc/fatfs_boot.S, src/base/misc/utilities.c,

src/emu-i386/simx86/codegen-x86.c, src/include/cpu.h:
GCC-2.95 and x86-64 VXD compatibility changes.
* [r1708] INSTALL, src/base/init/install.c:
Fixed -install for other DOSes than the supplied FreeDOS and
adjust README.
2006-11-16 Bart
* [r1707] src/emu-i386/simx86/sigsegv.c:
Fixed some 64-bit rip usage, and the division by zero exception.
* [r1706] configure, configure.ac, src/include/config.h.in,
src/include/dlmalloc.h:
Fixed gcc warning in dlmalloc and removed some obsolete autoconf
macros.
2006-11-15 Bart
* [r1705] src/arch/linux/Makefile.main:
Rearranged the messages after make install, so it is more clear
that the FreeDOS tarball is missing.
* [r1704] src/emu-i386/simx86/codegen-x86.c,
src/emu-i386/simx86/interp.c, src/emu-i386/simx86/modrm-gen.c,

* [r1700] ChangeLog, NEWS:
Updated NEWS and ChangeLog
2006-11-12 Bart
* [r1699] COPYING.DOSEMU, src/env/video/vgafonts.c:
Added VGA font and dlmalloc copyrights for completeness.
* [r1698] dist/autoemu.bat, dist/autoexec.bat, dist/config.emu,
dist/config.sys, src/arch/linux/Makefile.main,
src/base/init/install.c, src/base/misc/fatfs.c:
The previous approach had circular symbolic links for directories
which is bad as it confuses DOS programs. It seems clearer to
create a drive_z directory with contents equal to the old freedos
directory (even though there may not be a freedos present).
* [r1697] dist/dosemu, src/base/init/config.c,
src/base/init/install.c, src/emu.c, src/include/dos2linux.h,
src/include/emu.h, src/plugin/commands/unix.c:
Create no-prompt initial boot for DOSEMU+FreeDOS with a welcome
screen. The liability disclaimer just needs to be confirmed.
Removed the win4lin check from the dosemu script and moved the
terminal instructions to the main code.
* [r1696] dist/autoemu.bat, dist/autoexec.bat, dist/config.emu,
dist/config.sys, dosemu.spec.in, src/arch/linux/Makefile.main,
src/base/init/install.c, src/base/misc/fatfs.c:
Remove the tarballs with symlinks. Instead, point d: to the
systemwide FreeDOS directory during config.sys processing and use
z: after that. Install config.sys et al from dosemu.
* [r1695] etc/dosemu.conf, etc/global.conf,
src/base/dev/misc/lpt.c, src/base/init/lexer.l.in,
src/base/init/parser.y.in:
Use $_lpt1, $_lpt2, and $_lpt3 for printer configuration and
disable the printer IRQ for now since it's not used. Fixes
#1492201.
* [r1694] src/base/async/int.c, src/base/bios/setup.c,
src/include/int.h:
Fix missing LFN support after ctrl-alt-del (#1487899)
* [r1693] INSTALL, compiletime-settings,
compiletime-settings.devel, compiletime-settings.help, configure,
configure.ac, default-configure, src/emu.c,
src/plugin/sdl/acinclude.m4, src/plugin/sdl/configure,
src/plugin/sdl/configure.ac:
Use JIT cpuemu by default on x86-64, and don't force -m32 any
longer. Introduce target_bits compile time option to optionally
set -m32 or -m64. Updated SDL configure script and added a link
check for cross-compilation.
2006-11-11 Bart
* [r1692] dist/dosemu:
Use `id -ur` instead of $UID for dash compatibility.
* [r1691] src/arch/linux/async/signal.c, src/dosext/dpmi/dpmi.c,
src/emu-i386/cpu.c, src/include/cpu-emu.h:
Fix compilation with cpuemu off.
* [r1690] src/emu-i386/simx86/codegen-sim.c,
src/emu-i386/simx86/codegen-sim.h,
src/emu-i386/simx86/codegen-x86.c,
src/emu-i386/simx86/codegen-x86.h, src/emu-i386/simx86/emu86.h,
src/emu-i386/simx86/sigsegv.c, src/env/video/instremu.c,
src/env/video/vgaemu.c, src/include/vgaemu.h:
Implemented better VGAEMU support for simulated cpuemu and
eliminated the e_vga_base and e_vga_end variables.
* [r1689] src/arch/linux/async/signal.c,
src/emu-i386/simx86/cpu-emu.c, src/emu.c, src/env/video/vc.c,
src/include/emu.h, src/plugin/term/terminal.c:
Handle all async signals except those that call leavedos using
sigasync() which calls the correct sighandler using a function
pointer array. The real signal handlers are all set in
signal.c:signal_init() now. Add SIGWINCH & SIGPROF to the queue
block list because of their nature.
* [r1688] src/emu-i386/simx86/sigsegv.c,
src/emu-i386/simx86/trees.c:
Fixed some issues with self-modifying code.
* [r1687] src/emu-i386/simx86/codegen-x86.c,
src/emu-i386/simx86/tables.c, src/emu-i386/simx86/trees.c:
Removed GenBufSize hack and adjusted the op size array.
* [r1686] src/emu-i386/simx86/interp.c, src/env/video/instremu.c,
src/include/cpu.h:
Avoid "lahf" (may not be available on x86-64) and use READ_BYTE
for IS_IRET.
2006-11-10 Bart
* [r1685] src/emu-i386/simx86/codegen-x86.c,
src/emu-i386/simx86/cpu-emu.c, src/emu-i386/simx86/interp.c,
src/emu-i386/simx86/trees.c:
Fixed a bug in InvalidateSingleNode and DPMI TheCPU.eflags
handling. Under normal circumstances IOPL should never be set
there.
* [r1684] configure, configure.ac:
Add -lm to LIBS as DOSEMU now uses a few math functions.
* [r1683] src/emu-i386/simx86/fp87-sim.c:
Fixed rounding to integer in the FPU simulator.
* [r1682] src/emu-i386/simx86/codegen-x86.c:
Fix das/aas/aam for x86-64.
* [r1681] src/emu-i386/simx86/codegen-sim.c,
src/emu-i386/simx86/codegen-x86.c,
src/emu-i386/simx86/fp87-sim.c, src/emu-i386/simx86/interp.c:
Fixed ENTER/IDIV/DIV/IMUL/DAS and some FPU cases that failed with
the QEMU i386 emulator test program.
2006-11-09 Bart
* [r1680] src/emu-i386/simx86/interp.c:
Correct ofsseg array for DPMI
2006-11-08 Bart
* [r1679] src/emu.c, src/include/emu.h:
Forgotten sigjmp_buf declarations from r1677.
* [r1678] src/plugin/sdl/sdl.c:
Enable X background pause for SDL
* [r1677] src/base/misc/utilities.c, src/emu.c:
Use sigsetjmp/siglongjmp because signal handlers may be involved
in leavedos.
* [r1676] src/emu-i386/simx86/codegen-x86.c,
src/emu-i386/simx86/sigsegv.c:
Fix BSF and BSR, and don't use code patches for DPMI code for
cpuemu="full". Fixes Duke Nukem 3D in this mode.
* [r1675] src/emu-i386/simx86/interp.c:
Use the operand size instead of the address size for jump
destination masking. Fixes some issues with cpuemu in DPMI.
* [r1674] src/emu-i386/simx86/codegen-x86.c:
Fix vgaemu in compiled code.
* [r1673] src/emu-i386/simx86/codegen-sim.c,
src/emu-i386/simx86/interp.c:
Fixed IMUL regressions from r1670.
