Compiler implementation of the D programming language.

Source: e2ir.d

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.
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.
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.
elem generated
void toTraceGC(IRState* irs, elem* e, Loc* loc);
Replace call to GC allocator with call to tracing GC allocator.
IRState* irs to get function from
elem* e elem to modify
eloc 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.
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
generated call
