sigcen, `~%`, %sgcn

Core jet

~% is a synthetic rune, identifies a core for specific optimization.

Produces

Twig: [%sgcn p=term q=twig r=tyre s=twig]

Sample

p is a ++term q is a twig r is a ++tyre s is a twig

Examples

++  aesc                                                ::  AES-256
  ~%  %aesc  +  ~

  ++  en                                                ::  ECB enc

  ++  de                                                ::  ECB dec
    ~/  %de
    |=  [a=@I b=@H]  ^-  @uxH

Here we label the entire ++aesc core for optimization. You can see the jet in gen164/5/aesc.c.
