...an manually comparing the llc generated code with the source program, is there any other way of knowing which variables in the program are mapped to which registers? I was not able to find any suitable option for the same, so I'm wondering if there is a workaround. Thank you! ------------ Vijayaraghavan Murali (Vijay)

...I can obtain from the above. But, can you just confirm if this is the result of register allocation and that the "Reg (#)" lines represent the different registers used? Thank you once again!

...That is, the mapping of variables to physical registers. I'm comfortable with reading dwarf information. For eg, using gcc I would do: gcc -c -g hello.c ; dwarfdump hello.o Kindly guide me in performing the above steps. If they are not possible, is there any workaround?
