dmd.semantic3
Performs the semantic3 stage of semantic analysis, which finalizes function bodies and late semantic checks for templates, mixins, aggregates, and special members.
void
semantic3(Dsymbol
dsym, Scope*
sc);
Does semantic analysis on function bodies.
FuncDeclaration
search_toString(StructDeclaration
sd);
Search sd for a member function of the form:extern (D) string toString();
Parameters:StructDeclarationsd | struct declaration to search |
Returns:FuncDeclaration oftoString() if found,null if not
void
semanticTypeInfoMembers(StructDeclaration
sd);
Ensures special members of a struct are fully analysed before the backend emits TypeInfo.
Handles late semantic analysis for members likeopEquals,opCmp,toString,toHash, postblit, and destructor.
bool
checkClosure(FuncDeclaration
fd);
Determine whether the given function will need to allocate a closure_ and verify that such an allocation is allowed under the current compilation settings.
Whenever an error is emitted, every nested function that actually closes over a variable is listed in a supplemental diagnostic, together with the location of the captured variable’s declaration. (This extra walk is skipped when the compiler is gagged.)
