Building a wasm library, need to override .object._d_newitemT!T

Hello,

I've been developing a library[1] based on spasm for which I've implemented the druntime and currently it compiles web apps properly with TypeInfo, no GC, and it even uses diet templates.

I'm having a problem implementing the new keyword, so that I can start importing more libraries with minimal change. However, LDC calls .object._d_newitemT!T from the original druntime - which I need for compile-time function execution, but my implementation in module object doesn't override it in the compiler and the original implementation tries import core.stdc.time which errors out in wasm (with good reasons). Is there a compiler flag than I can use to override module templates?

Thanks in advance.

_d_newitemT!T is fairly new, what compiler version are you using?

Nevermind, I managed to get it working but I had to compile without including druntime and phobos and move everything into the library. I'm using ldc 1.36.0-beta1
