20 8. We add 8-bit or 16-bit imm as inline cache slot for some specific opcodes.
23 As we merge some "define-function" opcodes as one opcode, in function we add one field which record…
24 such that runtime can distinguish the "define-function" operations of different kinds.
26 We reuse the field 32-bit field `access_flags_` to encode Function Kind and Header index.
27 This will not introduce compatibility issue because the later 24-bit of `access_flags_` is unused i…
30 |<- 16-bit header index ->|<- 8-bit function kind ->|<- 8-bit original access flag ->|
39 As we use 16-bit to encode methodId, stringId and literalarrayId, the number of these Ids in one me…
45 3. In bytecode, we still use 16-bit literalarrayId rather than offset.

Dfile_format.md13 doesn't fit in 16-bit unsigned integer. It leads to application developer have to create several
