+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
 
   For example, if you distribute copies of the library, whether gratis
 or for a fee, you must give the recipients all the rights that we gave
 you.  You must make sure that they, too, receive or can get the source
-code.  If you link a program with the library, you must provide
-complete object files to the recipients so that they can relink them
-with the library, after making changes to the library and recompiling
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
 it.  And you must show them these terms so they know their rights.

+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
 permission to copy, distribute and/or modify the library.
 
-  Also, for each distributor's protection, we want to make certain
-that everyone understands that there is no warranty for this free
-library.  If the library is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original

+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
 
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that companies distributing free
-software will individually obtain patent licenses, thus in effect
-transforming the program into proprietary software.  To prevent this,
-we have made it clear that any patent must be licensed for everyone's
-free use or not licensed at all.
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
 
-  Most GNU software, including some libraries, is covered by the ordinary
-GNU General Public License, which was designed for utility programs.  This
-license, the GNU Library General Public License, applies to certain
-designated libraries.  This license is quite different from the ordinary
-one; be sure to read it in full, and don't assume that anything in it is
-the same as in the ordinary license.
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
 
-  The reason we have a separate public license for some libraries is that
-they blur the distinction we usually make between modifying or adding to a
-program and simply using it.  Linking a program with a library, without
-changing the library, is in some sense simply using the library, and is
-analogous to running a utility program or application program.  However, in
-a textual and legal sense, the linked executable is a combined work, a
-derivative of the original library, and the ordinary General Public License
-treats it as such.
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
 
-  Because of this blurred distinction, using the ordinary General
-Public License for libraries did not effectively promote software
-sharing, because most developers did not use the libraries.  We
-concluded that weaker conditions might promote sharing better.
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
 
-  However, unrestricted linking of non-free programs would deprive the
-users of those programs of all benefit from the free status of the
-libraries themselves.  This Library General Public License is intended to
-permit developers of non-free programs to use free libraries, while
-preserving your freedom as a user of such programs to change the free
-libraries that are incorporated in them.  (We have not seen how to achieve
-this as regards changes in header files, but we have achieved it as regards
-changes in the actual functions of the Library.)  The hope is that this
-will lead to faster development of free libraries.
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
 
   The precise terms and conditions for copying, distribution and
 modification follow.  Pay close attention to the difference between a
 "work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, while the latter only
-works together with the library.

-  Note that it is possible for a library to be covered by the ordinary
-General Public License rather than by this special one.

+ - more accurate VM86 emulation (can launch small DOS 16 bit
+   executables in wine).
+ - fixed push/pop fs/gs
+ - added iret instruction.
+ - added times() syscall and SIOCATMARK ioctl.
+
+version 0.1.3:
+
+ - S390 support (Ulrich Weigand)
+ - glibc 2.3.x compile fix (Ulrich Weigand)
+ - socketcall endian fix (Ulrich Weigand)
+ - struct sockaddr endian fix (Ulrich Weigand)
+ - sendmsg/recvmsg endian fix (Ulrich Weigand)
+ - execve endian fix (Ulrich Weigand)
+ - fdset endian fix (Ulrich Weigand)
+ - partial setsockopt syscall support (Ulrich Weigand)
+ - more accurate pushf/popf emulation
+ - first partial vm86() syscall support (can be used with runcom example).
+ - added bound, cmpxchg8b, cpuid instructions
+ - added 16 bit addressing support/override for string operations
+ - poll() fix
+ 
+version 0.1.2:
+
+ - compile fixes
+ - xlat instruction
+ - xchg instruction memory lock
+ - added simple vm86 example (not working with QEMU yet). The 54 byte
+   DOS executable 'pi_10.com' program was released by Bertram
+   Felgenhauer (more information at http://www.boo.net/~jasonp/pipage.html).
+
 version 0.1.1:
 
  - glibc 2.2 compilation fixes
  - added -s and -L options

+to install QEMU in /usr/local
 
-* On x86 you should be able to launch any program by using the
-libraries installed on your PC. For example:
+Tested tool versions
+--------------------
 
-    ./qemu -L / /bin/ls
+In order to compile QEMU succesfully, it is very important that you
+have the right tools. The most important one is gcc. I cannot guaranty
+that QEMU works if you do not use a tested gcc version. Look at
+'configure' and 'Makefile' if you want to make a different gcc
+version work.
 
-* On non x86 CPUs, you need first to download at least an x86 glibc
-(qemu-i386-glibc21.tar.gz on the qemu web page). Then you can launch
-the precompiled 'ls' x86 executable:

+
+[1] On Alpha, QEMU needs the gcc 'visibility' attribute only available
+    for gcc version >= 3.3.
+[2] Linux >= 2.4.20 is necessary for precise exception support
+    (untested).
+[3] 2.4.9-ac10-rmk2-np1-cerf2

-- optimize translated cache chaining (DLL PLT-like system)
+short term:
+----------
+- debug option in 'configure' script + disable -fomit-frame-pointer
+- Solaris display error with Cirrus VGA
+  (http://lists.gnu.org/archive/html/qemu-devel/2004-10/msg00390.html).
+- Precise VGA timings for old games/demos (malc patch)
+- merge PIC spurious interrupt patch
+- merge VNC keyboard patch
+- merge Solaris patch
+- merge ARM patches + self modifying code patch (Paul Brook)
+- warning for OS/2: must not use 128 MB memory
+- config file (at least for windows/Mac OS X)
+- commit message if execution of code in IO memory
+- update doc: PCI infos.
+- VNC patch + Synaptic patch.
+- basic VGA optimizations
+- test sysenter/sysexit and fxsr for L4 pistachio 686
+- physical memory cache (reduce qemu-fast address space size to about 32 MB)
+- better code fetch (different exception handling + CS.limit support)
+- do not resize vga if invalid size.
+- avoid looping if only exceptions
+- cycle counter for all archs
+- TLB code protection support for PPC
+- see openMosix Doc 
+- disable SMC handling for ARM/SPARC/PPC (not finished)
+- see undefined flags for BTx insn
+- user/kernel PUSHL/POPL in helper.c
+- keyboard output buffer filling timing emulation
+- return UD exception if LOCK prefix incorrectly used
+- test ldt limit < 7 ?
+- tests for each target CPU
+- fix CCOP optimisation
+- fix all remaining thread lock issues (must put TBs in a specific invalid
+  state, find a solution for tb_flush()).
+- fix arm fpu rounding (at least for float->integer conversions)
+- SMP support
+
+ppc specific:
+------------
+- TLB invalidate not needed if msr_pr changes
+- endianness bugs in do_load_fpscr and do_store_fpscr
+- SPR_ENCODE() not useful
+- enable shift optimizations ?
+
+lower priority:
+--------------
+- more friendly BIOS (logo)
+- int15 ah=86: use better timing
+- HDD geometry in CMOS (not used except for very old DOS programs)
+- suppress shift_mem ops
+- fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret)
+- sysenter/sysexit emulation
+- optimize FPU operations (evaluate x87 stack pointer statically)
+- add IPC syscalls
+- use -msoft-float on ARM
+- use kernel traps for unaligned accesses on ARM ?
+- handle rare page fault cases (in particular if page fault in helpers or
+  in syscall emulation code).
+- fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID)
 - more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit
   issues, fix 16 bit uid issues)
-- finish signal handing (fp87 state, more siginfo conversions)
-- verify thread support (clone() and various locks)
-- vm86 syscall support
-- overrides/16bit for string ops
-- make it self runnable (use same trick as ld.so : include its own relocator and libc)
-- improved 16 bit support 
-- fix FPU exceptions (in particular: gen_op_fpush not before mem load)
+- use page_unprotect_range in every suitable syscall to handle all
+  cases of self modifying code.
+- use gcc as a backend to generate better code (easy to do by using
+  op-i386.c operations as local inline functions).
+- add SSE2/MMX operations
