TODO

@@ -1,12 +1,15 @@
+- 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
