Hi all,
I've just managed to get the full DMD front-end to work in
WebAssembly (with skoppe's druntime fork).
Cool stuff. I recently picked up my wasm forks again and
updated to wasi 12, ldc 1.25.0 and the accompanying
druntime/phobos versions and got all tests to pass (those that
I didn't version out). I am currently in the process of
updating to latest ldc and latest druntime/phobos. Phobos has a
bunch of merge conflicts, but it should be doable if I find a
few hours.
Then there is the process of upstreaming a 5000+ line patch and
I probably need some help there. I reckon the WASI bindings are
pretty standalone so those should be easy to add, but there is
a sprawl of additions across almost all files due to not
supporting threads, fibers and catching exceptions.
Very cool! This all would not be possible with your wasm forks --
they are the saving grace here.
Regarding upstreaming the patch... that will be rather
challenging, but I would not mind contributing. I definitely
think the WASI bindings (if not all of the files in
`core.sys.wasi.*`) should be upstreamed first, as they're the
simplest to implement, and then the various druntime patches
should follow.
GC also needs some investigation (or malloc), as I keep get
spurious OOM errors. Could be because dmd is one hell of a memory
hog, but who knows.
