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* fillHole(Symbol* stmp, size_t* poffset, size_t offset2, size_t maxoff);

Generate elem to zero fill contents of Symbol stmp from *poffset..offset2. May store anywhere from 0..maxoff, as this function tries to use aligned int stores whereever possible. Update *poffset to end of initialized hole; *poffset will be >= offset2.

elem* appendDtors(IRState* irs, elem* er, size_t starti, size_t endi);

Add destructors

elem* toElemDtor(Expression e, IRState* irs);

Evaluate Expression, then call destructors on any temporaries in it.

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* filelinefunction(IRState* irs, Loc* loc);

Return an elem that is the file, line, and function suitable for insertion into the parameter list.

elem* buildArrayBoundsError(IRState* irs, ref const Loc loc);

Construct elem to run when an array bounds check fails.

Returns:

elem generated

void toTraceGC(IRState* irs, elem* e, 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
eloc	to get file/line from
