-- fix printf for doubles (fp87.c bug ?)
-- make it self runnable (use same trick as ld.so : include its own relocator and libc)
-- better FPU comparisons (ucom/com)
+
+- fix arm fpu rounding (at least for float->integer conversions)
+- fix CCOP optimisation
+- optimize FPU operations (evaluate x87 stack pointer statically) 
+- fpush not before mem load restarting
+- fix all remaining thread lock issues (must put TBs in a specific invalid
+  state, find a solution for tb_flush()).
+- add gcc 2.96 test configure (some gcc3 flags are needed)
+- add IPC syscalls
+- submit a patch to fix DOSEMU coopthreads
+
+lower priority:
+--------------
+- use -msoft-float on ARM
+- use kernel traps for unaligned accesses on ARM ?
+- handle rare page fault cases (in particular if page fault in heplers 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)
+- 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
