Hi,
following simple code works well with dmd but LDC won't let me access member variables of a struct that way. How does is work? Is there nice method compatible with both LDC and DMD?

thanks in advance

module app.d;

import std.stdio;

struct test {
        uint a = 42;
        uint b = 7;

        uint getA() {
                uint temp;
                asm {
                        mov RBX, this;
                        mov EAX, a[RBX];
                        mov temp, EAX;
                }
                return temp;
        }
}

public static void main() {
        writeln("asm 'this' test");
        test t;
        writeln("test.getA(): ", t.getA());
        assert(t.getA() == t.a, "getA() failed");
}

Hi!

That's really a deviation from dmd. Please file an issue for it: https://github.com/ldc-developers/ldc/issues

Please not that DMD-style inline assembler is not the best solution for ldc. If you need maximum performance than you should think about creating a solution with ldc style inline assembler.

Kai
