https://issues.dlang.org/show_bug.cgi?id=14872 --- Comment #1 from Daniel <wyrlon@gmx.net> --- I tested that it works with ldc2 and saw some interesting things when disassembling at asm.dlang.org dmd -m32 lea %cs:0x28,%eax mov %eax,-0x8(%ebp) lea %cs:0x30,%eax mov %eax,-0x4(%ebp) dmd -m64 cs mov %rax,%rax mov %rax,-0x10(%rbp) cs mov %rax,%rax mov %rax,-0x8(%rbp) ldc2 -m64 leaq .L_Dmain_lbl1, %rax movq %rax, -72(%rbp) leaq .L_Dmain_lbl2, %rax movq %rax, -80(%rbp) -- |

I think that has something to do with Intel x64 being position-independent, meaning that "lea RAX, lbl1" is not going to do what you want. It looks like in case of DMD, it's generating nonsense code (mov eax, eax), but it could still use the offset relative to some base. In any case, it certainly won't be the actual in-address memory of the code at that label (so that you can "jmp" to it). So, your example is a bit nonsensical, but DMD should still not be emitting garbage code, and either generate an error or use some other kind of offset (so that it's at least possible to use the offset in calculations to produce something useful). -- |
