as a follow up of Parsing and translating Perl Regexes

Could someone please point me to the code emitting the Regex Opcodes from use re "debug"

For instance 

    
Compiling REx "(\.|[%"']|x)"
Final program:
   1: OPEN1 (3)
   3:   BRANCH (6)
   4:     EXACT <.> (21)
   6:   BRANCH (18)
   7:     ANYOF["'] (21)
  18:   BRANCH (FAIL)
  19:     EXACT <x> (21)
  21: CLOSE1 (23)
  23: END (0)
minlen 1 
Freeing REx: "(\.|[%"']|x)"

[download]

where do the Opcodes OPEN BRANCH ANYOF ... come from, where do I find a complete list?

I looked into perlreguts , the source of the re pragma and in the perl5 github mirror but couldn't indentify the code, most probably because I'm not a C programmer.

but they don't include things like TRIE-EXACT
