What does sval mean?
It means that there is a symbol (given x86_64 target, 0x604420 would usually mean it's a .text symbol) with that value in the binary, and rbp happens to point to that symbol.这意味着在二进制中有一个具有该值的符号（给定x86_64目标， 0x604420通常意味着它是一个.text符号），并且rbp恰好指向该符号。
You can run nm your-binary | grep sval你可以运行nm your-binary | grep sval nm your-binary | grep sval and see that symbol. nm your-binary | grep sval并看到那个符号。
Does it means string val?
No, nothing of the sort.不，什么都没有。
