I get error in such simple test with two variables:



$ echo test|awk '$2 != ""? o="ABC" r="123" : o="123 r="ABC"ENDprint "o:"o" r:"r'
awk: cmd. line:1: $2 != ""? o="ABC" r="123" : o="123 r="ABC"ENDprint "o:"o" r:"r
awk: cmd. line:1: ^ syntax error
awk: cmd. line:1: $2 != ""? o="ABC" r="123" : o="123 r="ABC"ENDprint "o:"o" r:"r
awk: cmd. line:1: ^ syntax error
awk: cmd. line:1: $2 != ""? o="ABC" r="123" : o="123 r="ABC"ENDprint "o:"o" r:"r
awk: cmd. line:1: ^ unterminated string
$


with single variables it works fine:



$ echo test|awk '$1 != ""? o="ABC" : o="123"ENDprint "o:"o'
o:ABC
$ echo test|awk '$2 != ""? o="ABC" : o="123"ENDprint "o:"o'
o:123

          You can't really do that with the ? : operator, since it can handle a single value only, and two assignments would generate two values.



          Use an actual if statement instead:



          $ echo test|awk ' if ($2 != "") o="ABC"; r="123" else o="123"; r="ABC" END print "o:"o" r:"r'
          o:123 r:ABC

                    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.
