elem* `addressElem`(elem* `e`, Type `t`, bool `alwaysCopy` = false);
  Take address of an elem.
elem* `array_toPtr`(Type `t`, elem* `e`);
  Convert array to a pointer to the data.
elem* `array_toDarray`(Type `t`, elem* `e`);
  Convert array to a dynamic array.
elem* `sarray_toDarray`(Loc `loc`, Type `tfrom`, Type `tto`, elem* `e`);
elem* `getTypeInfo`(Type `t`, IRState* `irs`);
StructDeclaration `needsPostblit`(Type `t`);
  Determine if `t` is a struct that has postblit.
StructDeclaration `needsDtor`(Type `t`);
  Determine if `t` is a struct that has destructor.
void `clearStringTab`();
  Reset stringTab[] between object files being emitted, because the symbols are local.
elem* `toElemDtor`(Expression `e`, IRState* `irs`);
  Convert Expression to elem, then append destructors for any temporaries created in elem.
  Parameters:

  Expression `e` | Expression to convert
  irstate | context

  Returns:
  generated elem tree
Symbol* `toStringSymbol`(const(char)* `str`, size_t `len`, size_t `sz`);
  Write read-only string to object file, create a local symbol for it. Makes a copy of `str`'s contents, does not keep a reference to it.
  Parameters:

  const(char)* `str` | string
  size_t `len` | number of code units in string
  size_t `sz` | number of bytes per code unit
  comdat | emit string in its own comdat (default is read-only segment). Comdats are useful when linker does not coalesce redundant strings.

  Returns:
  Symbol
Symbol* `toStringSymbol`(StringExp `se`);
  Turn StringExp into Symbol.
elem* `buildArrayBoundsError`(IRState* `irs`, ref const Loc `loc`);
  Construct elem to run when an array bounds check fails.
  Parameters:

  IRState* `irs` | to get function from
  Loc `loc` | to get file/line from

  Returns:
  elem generated
void `toTraceGC`(IRState* `irs`, elem* `e`, ref const Loc `loc`);
  Replace call to GC allocator with call to tracing GC allocator.
  Parameters:

  IRState* `irs` | to get function from
  elem* `e` | elem to modify in place
  Loc `loc` | to get file/line from

elem* `callCAssert`(IRState* `irs`, Loc `loc`, Expression `exp`, Expression `emsg`, const(char)* `str`);
  Generate call to C's assert failure function. One of `exp`, `emsg`, or `str` must not be `null`.
  Parameters:

  IRState* `irs` | context
  Loc `loc` | location to use for assert message
  Expression `exp` | if not `null` expression to test (not evaluated, but converted to a string)
  Expression `emsg` | if not `null` then informative message to be computed at run time
  const(char)* `str` | if not `null` then informative message string

  Returns:
  generated call
