I have a function



f()
 echo 777



and a variable to which I assign the "return value" of the function.



x=$(f)


Very concise! However, in my real code, the variable and function names are quite a bit longer and the function also eats positional arguments, so that concise line above, gets very long. Since I like to keep things tidy, I would like to break the code above in two lines.



x=
$(f)


Still works! But: keeping things tidy also means respecting the indentation, so that gives something like



if foo
 x=
 $(f)
fi


which does not work anymore due to whitespaces! Is there a good workaround for this?

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
