Bug 14044 – dmd generates spurious functions in object file created from empty module

Looking at http://asm.dlang.org, with DMD 2.065 the object file contains no functions. But with 2.066.1 there are a few spurious functions generated: _D6object7__arrayZ push %rbp mov %rsp,%rbp sub $0x10,%rsp mov %edi,-0x8(%rbp) mov -0x8(%rbp),%edx mov %rdx,-0x10(%rbp) mov 0x0(%rip),%rdx # 19 <_D6object7__arrayZ+0x19> mov 0x0(%rip),%rdi # 20 <_D6object7__arrayZ+0x20> mov %rdx,%rsi mov -0x10(%rbp),%rdx callq 2c <_D6object7__arrayZ+0x2c> nopl 0x0(%rax) void object.__assert(int) push %rbp mov %rsp,%rbp sub $0x10,%rsp mov %edi,-0x8(%rbp) mov -0x8(%rbp),%edx mov %rdx,-0x10(%rbp) mov 0x0(%rip),%rdx # 19 <void object.__assert(int)+0x19> mov 0x0(%rip),%rdi # 20 <void object.__assert(int)+0x20> mov %rdx,%rsi mov -0x10(%rbp),%rdx callq 2c <void object.__assert(int)+0x2c> nopl 0x0(%rax) void object.__unittest_fail(int) push %rbp mov %rsp,%rbp sub $0x10,%rsp mov %edi,-0x8(%rbp) mov -0x8(%rbp),%edx mov %rdx,-0x10(%rbp) mov 0x0(%rip),%rdx # 19 <void object.__unittest_fail(int)+0x19> mov 0x0(%rip),%rdi # 20 <void object.__unittest_fail(int)+0x20> mov %rdx,%rsi mov -0x10(%rbp),%rdx callq 2c <void object.__unittest_fail(int)+0x2c> leaveq retq ...
