十分有趣，值得一讀。

TODO:
1' find out <- this is llvm translation database
2' find out the translator engine <- llvm-op.h is the engine
3' add translator engine into llvm_gen_code
4' in the slide, you should mention the architecture of the framework, and
indicate which is done.
5' show the target instructions and say that you are going to build the translation function in the next week

QEMU programming notes
profiler => can we ignore it?
inhibit irq => true if hardware interrupts must be disabled for the next instruction
TF cpu flag => 8th bit of flags in x86, trap flag, system flag
jmp_opt in DisasContext => indicate whether to do block linking
what is GRP1? in
what is modrm?
Q: what are my target instructions?
test program is in ~/research/qemu/src/branches/llvm-qemu/tests/
add-i386.c
tmp.c
stay in disas_insn() in target-i386/translate.c
line 4122
I need a C programming language book
1' create a new fucking useless function!
mov
0x89 source is register, destination could be register
or memory location related to a register
