bases on OCaml-4.12.1 and WASI-SDK 19
support for using the tail call extension of WebAssembly
(-enable-tail-call), PR#36.
support for using the exception handing extension of WebAssembly
(-enable-exception-handling)
reworked the way exceptions are propagated. If the exception is
raised in OCaml code, it is passed up by returning the special
value 0 to the caller (which has to check for it). If the
exception is raised in C code, it is using the special
"wasicaml_try" / "wasicaml_throw" host functions that are expected
to be available (unless you -enable-exception-handling, in which
case native WebAssembly exceptions are used in this case).
The upside of this change is a simplified code generation.
The downside is that the backtraces contain less information.
(PR#40)
more local variables: it is now tried to keep the top N
values of the stack in local variables. This gives the
JIT engine more opportunities to optimize the binary code.
However, more save/restore code is now also required,
so the code is less compact. For this reason, a new
-compact-code command-line option was added. (PR#39)
switching to wasi-js as the npm package to implement
WASI in nodejs.
