- nkurz 12y agoGreat short intro! One other useful thing I'd add is that you don't have to have the register window open to see the contents of registers --- they can also be printed like other variables while you are in 'layout asm'. Or you can use 'layout split' which shows both source and assembly. For example, "p/t $rax" will print the contents of %rax. Printing the floating point registers can be a little awkward, since they are written as a long union. But "p/f $xmm0.v2_double" will show just the two doubles, etc.
- suprjami 12y agoOne thing I like about the register view is the highlighting on register change. This is great when an instruction changes a register beyond a basic MOV/ADD/SUB. Using register view ended up being the "lightbulb" moment which helped me understand how stack frames are built.
