Below is a description of all opcodes we current support in the Eiffel interpreter. They are sorted

BC_START

Description

Entry point of a routine.

arguments

• routine_id: 32 bits
• body_id: 32 bits
• result type: 32 bits
• number of arguments: 16 bits
• number of locals: 16 bits
• type of each local
• flag for argument cloning: 8 bits (If it is set (aka different of BC_NO_CLONE_ARG), read the type of arguments which need cloning).
• routine name: null terminated CHARACTER_8 string
• dynamic type where feature is written in: 16 bits
• flag for rescue clause presence: 8 bits (If present, offset to the rescue clause: 32 bits).
