+Deprecated opcodes (branches/leo-ctx5 first)
+
+findclass(out INT, in STR)
+
+ returns a boolean bit if the class exists. The opocde name is misleading
+ doesn't conform to other find_ ops and the functionality is covered by
+ C<find_type>.
+
+ use find_type > 0 instead
+
+newsub(in INT, in INT, labelconst INT, labelconst INT)
+
+ Creates a sub in P0 and a continuation in P1. It was a premature
+ attempt to be able to create a return continuation outside a loop.
+ This isn't needed anymore due to continuation recycling and the opcode
+ also has implicit register usage (P0, P1).
+
+ use 3 arg newsub, find_global, set_p_pc, or just foo() syntax
+
+isnull(in PMC, labelconst INT)
+
+ Despite it's name this is a branching opcode. The name is misleading.
+
+ use if_null or unless_null instead.
+
+Register stack opcodes
+
+pop{i,s,p,n}, popbottom{i,s,p,n}, poptop{i,s,p,n},
+push{i,s,p,n}, pushbottom{i,s,p,n}, pushtop{i,s,p,n},
+savetop, restoretop,
+
+ With the upcoming variable-sized register frame handling these opcodes
+ will stop working and are useless anyway.
+
+ use saveall/restoreall (whole register frame) or
+ user stack opcodes save/restore instead.
+
+Integer stack opcodes
+
+intsave/intrestore/intdepth
+
+ The integer stack was an invention for rx_ opcodes, but as it's a
+ global stack, regexen using these opcodes aren't reentrant.
+
+ use a ResizableIntegerPMC instead and standard keyed access
+
+set_eh
+
+ already dprecated
+ use push_eh
+
+die, die(in INT), die_hard(int INT, in INT)
+
+ die is a special case of die_hard, but the name of the latter isn't
+ really nice. Therefore die_hard with be renamed to die, the 2 argument
+ form of die survives.
