Sorry I didn't phrase my question accurately. Presumably to
use above with the mnemonics I would need additional mixin
templates where the aggregate type and member etc would need
to be parameters?
You can use just string parameters instead of enums, then you
can pass arbitrary arguments to the instructions. The compiler
will tell you if something is wrong with the syntax of the
generated assembly.
Okay thank you. Sigh. It would be so much simpler to be able to
just define mnemonics for registers.
Anyway, another question:
Does the compiler generate appropriate unwind information on
Win64? Prsumably if a function is marked 'naked' then it
doesn't?
Thanks and Regards

yeah about stack frame..., also don't forget to mark the asm
block "pure nothrow" if possible...
It's not documented but the syntax is like that:
```
void foo()
{
asm pure nothrow
{
naked;
ret;
}
}
```
