+version 0.3:
+ - added fnsave, frstor, fnstenv, fldenv FPU instructions
+ - added FPU register save in signal emulation
+ - ARM port
+
version 0.2:
- PowerPC disassembly and ELF symbols output (Rusty Russel)
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.

Documentation
-------------
-- fix iret/lret/fpush not before mem load restarting
+- 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()).
-- handle fp87 state in signals
- add gcc 2.96 test configure (some gcc3 flags are needed)
-- optimize FPU operations (evaluate x87 stack pointer statically)
- 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)
