#+title: representation of Scheme types
|
||||
|
||||
the Scheme unitype is encoded as ~(ref eq)~ with immediates in ~(ref i31)~ and heap objects in ~$heap-object~:
|
||||
#+begin_src wat
|
||||
(type $heap-object (sub (struct (field $hash (mut i32)))))
|
||||
#+end_src
|
||||
|
||||
* immediates
|
||||
|
||||
all immediates are stored in ~(ref i31)~ and thus must fit in 31 bits. the most important immediate, the integer, is indicated by a null low bit.
|
||||
#+begin_example
|
||||
XXXX XXXX XXXX XXXX XXXX XXXX XXXX XX00
|
||||
||
|
||||
|\ used by wasm's i31 rep
|
||||
zero indicates a 30-bit fixnum /
|
||||
in the upper bits
