* wasm: Don't try to print the function results if it traps
* LibWasm: Inline some very hot functions
These are mostly pretty small functions too, and they were about ~10%
of runtime.
* LibWasm+Everywhere: Make the instruction count limit configurable
...and enable it for LibWeb and test-wasm.
Note that `wasm` will not be limited by this.
* LibWasm: Remove a useless use of ScopeGuard
There are no multiple exit paths in that function, so we can just put
the ending logic right at the end of the function instead.
This commit is a fairly large refactor, mainly because it unified the
two different ways that existed to represent references.
Now Reference values are also a kind of value.
It also implements a printer for values/references instead of copying
the implementation everywhere.
This allows multiply different kinds of interpreters to be used by the
runtime; currently a BytecodeInterpreter and a
DebuggerBytecodeInterpreter is provided.
This will simply "link" any given module instances and produce a list of
external values that can be used to instantiate a module.
Note that this is extremely basic and cannot resolve circular
dependencies, and depends on the instance order.
Managing the instantiated modules becomes a pain if they're on the
stack, since an instantiated module will eventually reference itself.
To make using this simpler, just avoid copying the instance.
This fixes a FIXME and will allow linking only select modules together,
instead of linking every instantiated module into a big mess of exported
entities :P
Previously, this was parsing only one kind because I mistakenly assumed
that they all had the same shape, now it can parse two kinds, and will
return NotImplemented for the rest.
This adds very basic support for module instantiation/allocation, as
well as a stub for an interpreter (and executions APIs).
The 'wasm' utility is further expanded to instantiate, and attempt
executing the first non-imported function in the module.
Note that as the execution is a stub, the expected result is a zero.
Regardless, this will allow future commits to implement the JS
WebAssembly API. :^)
