just fyi but `int 3;` works just as well in 32 bit as 64
Yeah, that's why I noted that there's also D_InlineAsm_X86 but I
just didn't bother adding it.

With LDC, you have:
```D
import ldc.intrinsics: llvm_debugtrap;
```
Combining that with previous answers, you can make something
like this:
```D
void debugbreak() nothrow @nogc @trusted {
version(D_InlineAsm_X86_64) {
asm nothrow @nogc {
int 3;
}
} else version(LDC) {
import ldc.intrinsics: llvm_debugtrap;
llvm_debugtrap();
} else {
assert(0); // No `breakPoint` for this compiler configuration
}
}
```
Shouldn't it be this instead, unless D_InlineAsm_X86_64 isn't
available for ldc?
There's also D_InlineAsm_X86 btw.
```D
void debugbreak() nothrow @nogc @trusted {
version(LDC) {
import ldc.intrinsics: llvm_debugtrap;
llvm_debugtrap();
} else version(D_InlineAsm_X86_64) {
asm nothrow @nogc {
int 3;
}
} else {
assert(0); // No `breakPoint` for this compiler configuration
}
}
```

yeah that's how i do it in dmd too

I tried using raise(SIGINT) from core.stdc.signal, but that just closes the debugger (I thought that was the same, seems like I was wrong). SIGINT is not an interrupt, it's a POSIX signal.

Why not just:
asm { int 3; }
?
Just tested in gdb, it worked.

Microsofts C++ compiler provides the __debugbreak function, which on x86 emits interrupt 3, which will cause the debugger to halt. What is the equivalent in D?
