Finding register set being used in program

amit gangarade · #1 (**permalink**) 09-22-2009

How can i find( or list) contents of all registers being used by my program?
Is there any system call or library available for this?

At runtime in my c/c++ program. At runtime using may be some assembly hack!!!!!!!!!!!

Disassemble it and find all the registers referenced in the binary machine code.

- if you want the contents of the registers, you'll have to use gdb (the gnu debugger) , and after running your program (for a hitherto uncertain time) ,
use the 'info registers' command to examine the registers' contents ;

- exactly at which point in time the register snapshot will have to be taken,
only you (the author) can tell ;

good luck, and success !
