1Correctness issues:
2
3- some eflags manipulation incorrectly reset the bit 0x2.
4- SVM: test, cpu save/restore, SMM save/restore. 
5- x86_64: lcall/ljmp intel/amd differences ?
6- better code fetch (different exception handling + CS.limit support)
7- user/kernel PUSHL/POPL in helper.c
8- add missing cpuid tests
9- return UD exception if LOCK prefix incorrectly used
10- test ldt limit < 7 ?
11- fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret)
12- full support of segment limit/rights 
13- full x87 exception support
14- improve x87 bit exactness (use bochs code ?)
15- DRx register support
16- CR0.AC emulation
17- SSE alignment checks
18- fix SSE min/max with nans
19
20Optimizations/Features:
21
22- add SVM nested paging support
23- add VMX support
24- add AVX support
25- add SSE5 support
26- fxsave/fxrstor AMD extensions
27- improve monitor/mwait support
28- faster EFLAGS update: consider SZAP, C, O can be updated separately
29  with a bit field in CC_OP and more state variables.
30- evaluate x87 stack pointer statically
31- find a way to avoid translating several time the same TB if CR0.TS
32  is set or not.
33- move kqemu support outside target-i386.
