nothrow @nogc void `dt_free`(dt_t* `dt`);
  Free a data definition struct.
nothrow @nogc void `dt_term`();
  Free free list.
nothrow @nogc void `dtpatchoffset`(dt_t* `dt`, uint `offset`);
nothrow @nogc void `init_common`(Symbol* `s`);
  Make a common block for s.
nothrow @nogc uint `dt_size`(const(dt_t)* `dtstart`);
  Compute size of a dt
nothrow @nogc bool `dtallzeros`(const(dt_t)* `dt`);
  Return true if dt is all zeros.
nothrow @nogc bool `dtpointers`(const(dt_t)* `dtstart`);
  Return true if dt contains pointers (requires relocations).
nothrow @nogc void `dt2common`(dt_t** `pdt`);
  Turn DT_azeros into DTcommon
struct `DtBuilder`;
  nothrow @nogc dt_t* `finish`();
    Finish and return completed data structure.
  nothrow @nogc void `nbytes`(uint `size`, const(char)* `ptr`);
    Append data represented by ptr[0..size]
  nothrow @nogc void `abytes`(tym_t `ty`, uint `offset`, uint `size`, const(char)* `ptr`, uint `nzeros`);
    Write a reference to the data ptr[0..size+nzeros]
  nothrow @nogc void `dword`(int `value`);
    Write 4 bytes of value.
  nothrow @nogc void `size`(ulong `value`);
    Write a size_t value.
  nothrow @nogc void `nzeros`(uint `size`);
    Write a bunch of zeros
  nothrow @nogc void `xoff`(Symbol* `s`, uint `offset`, tym_t `ty`);
    Write a reference to s+offset
  nothrow @nogc void `xoff`(Symbol* `s`, uint `offset`);
    Create reference to s+offset
  nothrow @nogc dt_t* `xoffpatch`(Symbol* `s`, uint `offset`, tym_t `ty`);
    Like xoff(), but returns handle with which to patch 'offset' value.
  nothrow @nogc Symbol* `dtoff`(dt_t* `dt`, uint `offset`);
    Create a reference to another dt.
    Returns:
    the internal symbol used for the other dt
  nothrow @nogc void `coff`(uint `offset`);
    Write reference to offset in code segment.
  nothrow @nogc void `cat`(dt_t* `dt`);
    Append dt to data.
  nothrow @nogc void `cat`(ref DtBuilder `dtb`);
    Append dtb to data.
  nothrow @nogc void `repeat`(dt_t* `dt`, size_t `count`);
    Repeat a list of dt_t's count times.
  nothrow @nogc uint `length`();
    Return size of data.
  nothrow @nogc bool `isZeroLength`();
    Return true if size of data is 0.
nothrow @nogc dt_t* `dt_get_nzeros`(uint `n`);
  Temporary hack to initialize a dt_t* for C.
