Changelog

+version 0.2:
+
+ - PowerPC disassembly and ELF symbols output (Rusty Russel)
+ - flock support (Rusty Russel)
+ - ugetrlimit support (Rusty Russel)
+ - fstat64 fix (Rusty Russel)
+ - initial Alpha port (Falk Hueffner)
+ - initial IA64 port (Matt Wilson)
+ - initial Sparc and Sparc64 port (David S. Miller)
+
 version 0.1.6:
 
  - automatic library search system. QEMU can now work with unpatched

TODO

+- fix gcc 2.96 compile bug 
 - fix thread locks
 - optimize translated cache chaining (DLL PLT-like system)
-- fix thread stack liberation (use kernel 2.5.xxx CLONE_CHILD_CLEARTID)
+- fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID)
 - fix x86 stack allocation
 - fix iret/lret restarting
 - 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)
-- make it self runnable (handle self modifying code, relocate stack
-  and dyn loader)
 - fix FPU exceptions (in particular: gen_op_fpush not before mem load)
+- handle self-modifying code (track mmap and mark all pages containing
+  translated code as readonly. use a custom signal handler to flush
+  parts of the translation cache if write access to a readonly page
+  containing translated code).
+- use gcc to compile to static code
