Why don't we have bitwise rotation operators in C / C ++?

What stood in the way of new operators that have been added to the C / C ++ standard, for example <<<

, and >>>

for bit-wise operations of the left and right rotation? Is there a reason why standards organizations cannot include such operators in a future specification?

I know there are other ways to do this:

• &

>>

|

<<
  
  combo
• Internal functions
• Inline assembly

Problems with these workarounds:

• Performance
• Readability
• Potentially more complex code generation
• Platform / Compiler Dependency

To me it looks like an inconsistency. If they're already making an effort to provide simple, readable high-performance operators for &

<<

and >>

, it shouldn't be any harder to support 8-, 16-, 32-, and 64-bit signed / unsigned values.
