so you'll get
Error: function `runnable.NG` label
`_D8runnable__T2ngVii1ZQiFNaNbNiNfZi` is undefined
Error: function `runnable.NG` label
`_D8runnable__T7ngVii2ZQnFNaNbNiNfZi` is undefined
So to keep things simples the idea is to provide a valid
function identifier in the asm. I've used compiler explorer
to get the __valid__ mangled version
(https://godbolt.org/z/WYMqMhnWG). No luck.
Is that even possible ?
The static foreach does not seem to generate the symbols in a
classic way tho...
assume CS:.text._D8runnable__T2ngVii1ZQiFNaNbNiNfZi
but on the other hand the error message is not a linker one
nah its the asm block not having access to templates
That is not the problem. Here we accept that inline assemby is
"lazily handled", so you cannot mix pure (in the sense of high
level) D language with asm. The problem is really that the
function identifier should be ignored until the linking phase.
Remember that we have generated the right name using "compiler
explorer".
.mangleof is correct and should give the same result as godbolt;
if you want to use a managle you would have to extern c it,
otherwise it isnt a symbol
```d
// The OK part
int ok(int i:1)(){return 1;}
int ok(int i:2)(){return 2;}
enum mangle=ok!1.mangleof;
pragma(msg,mangle);
mixin("extern(C) int "~mangle~"();"); // <======
void OK()
{
ulong r;
asm
{
xor R8, R8;
call _D9onlineapp__T2okHVii1ZQjFNaNbNiNfZi;
add R8, RAX;
mov r, R8;
}
assert(r == 1);
}
int main()
{
OK();
return 0;
}
```
