[Valgrind-users] access guest instruction in tool instrumentation code

[tejas <kk...@gm...>]

Hi,

I am writing a tool to extract dynamic trace from a program run using 
valgrind. I am using a modified version of lackey to accomplish this. I 
understand that valgrind prints out the assembly or x86(in this case) 
instructions of the program when the --profile-flags option is used. I 
was wondering if there is a way to know what the guest instruction is 
(like addl $2, %eax), given a particular Imark? Is there a function that 
can do this? If yes, can i call this function, giving the IMARK 
information as input, from the instrumentation code?

Thanks

Tejas
