[Question] About GC heap area and linear memory

[lum1n0us]

I got some confusion after reading the overview and MVP, which are:

• Is "GC heap area" still a part of the linear memory? Or it is a separate area outside the sandbox.
• When creating a "GC heap object", should I consider it like:
  • new() something or malloc() something in the linear memory, (like calling malloc() in wasm applications)
  • or just ask runtime to give me an object and don't care where it comes from(I mean even if it is from system/embedded/runtime managed heap, not wasm application managed(by wasi-libc likes) heap)

The GC heap is encapsulated in the engine's runtime and completely separate from any linear memory. The runtime manages it, so indeed you don't need to care.
