hello @zarlo, should not we focus on x64 since NativeAOT barely supports x32? I think we should focus on x64 and ARM

Are we sure we need the X# builder API surface? While it would be nice, I think it'd be a lot more code to maintain, especially given the fact that x86-64 has a lot of ISA extensions itself. If we're limiting inline assembly to the minimum, wouldn't X# be extremely underutilized in this scenario?

I believe that we could get by if we only did what is currently known as LiteralAssemblerCode in IL2CPU. That is, when defining an inline assembly method, we would do the following:

[InlineAssembly]
public static void ReadCr3() {
  InlineAssembly.Literal("""
    mov rax, cr3
    ret
  """);
}

...or, alternatively:

[InlineAssembly(
  """
    mov rax, cr3
    ret
  """
)]
public static extern void ReadCr3();

The latter would be easier to manipulate from compile-time IL weavers. That is, we would only need to read custom attribute data, rather than interpret known IL patterns.

I think we may discuss with coredevs regarding XSharp @zarlo
before completely removing it
to identify our objectives and needs

@valentinbreiz ill keep working on the build tasks i am not (build asm and link the objects in to one) as we will need it either way

[zarlo]

im going to wait for #43 so this can be easily tested
