-// this is a hack to support mnemonics for the FEVM extension opcodes
-// it is really ugly, but the etk assmebler doesn't currently support any way to
-// directly embed (otherwise invalid) asm instructions in the stream... sigh.
-// Ideally we would just do them as macros like
-// %macro methodnum()
-//   0xb1
-// %end
-// Note that to add insult to injury, macros cannot %include_hex... double sigh.
-// So f*ck it, we'll just hack this until there is support.
