Hi Arthur,

Thank you for your quick answer. Your suggestion about reading source
registers is working very well. However, there is still work for me.
Practically two regs are ANDed, so which regs should I read?
Apparently(when I look at build/X86/arch/x86/generated/decoder.cc)
first two of src regs are 'real' operands. I got Integer instructions
of hello world program written to a text file. When I look at these
instructions and their operands, about %90 of "xor" and "and"
instructions' first two operands are the same. At first, I thought
this may be because of the program. Then I tried with some CPU2006
benchmarks, the results were similar to hello world porgram. My
question is how can I decide which src regs to read?


Best regards.
