Common definitions
Compiler implementation of the D programming language.
Authors:
struct Srcpos;
Position in source file
pure nothrow @safe void set(const(char)* filename, uint linnum, int charnum);
Set fields of Srcpos
Parameters:
const(char)* filename file name
uint linnum line number
int charnum character number
struct Pstate;
Current 'state' of the compiler. Used to gather together most global variables. This struct is saved/restored during function body parsing.
struct Cstate;
Global variables.
alias ClassDeclaration_ = void*;
Basic blocks: Basic blocks are a linked list of all the basic blocks in a function. startblock heads the list.
alias BC = int;
Basic block control flow operators.
struct BlockRange;
Range for blocks.
alias func_flags_t = uint;
Functions
struct meminit_t;
Item in list for member initializer.
struct baseclass_t;
Base classes are a list of these.
alias mptr_flags_t = char;
For virtual tables.
struct TMF;
Information gathered about externally defined template member functions, member data, and member classes.
struct TME;
Information gathered about primary member template explicit specialization.
struct TMNE;
Information gathered about nested explicit specializations.
struct TMNF;
Information gathered about nested class friends.
struct template_t;
Special information for class templates.
alias enum_flags_t = uint;
Special information for enums.
alias struct_flags_t = uint;
Special information for structs.
nothrow @nogc @trusted inout(Symbol)* list_symbol(inout list_t lst);
Symbol Table
alias pflags_t = uint;
Function parameters: Pident identifier of parameter Ptype type of argument Pelem default value for argument Psym symbol corresponding to Pident when using the parameter list as a symbol table For template-parameter-list: Pident identifier of parameter Ptype if NULL, this is a type-parameter else the type for a parameter-declaration value argument Pelem default value for value argument Pdeftype default value for type-parameter Pptpl template-parameter-list for template-template-parameter Psym default value for template-template-parameter For template-arg-list: (actual arguments) Pident NULL Ptype type-name Pelem expression (either Ptype or Pelem is NULL) Psym SCtemplate for template-template-argument
nothrow @nogc @trusted EHmethod ehmethod(Symbol* f);
Parameters:
Symbol* f function symbol
Returns:
exception method for f
alias FL = ubyte;
Element types. These should be combined with storage classes.
struct EEcontext;
Srcfiles
This is to support compiling expressions within the context of a function.
struct dt_t;
Data definitions DTibytes 1..7 bytes DTabytes offset of bytes of data a { a data bytes } DTnbytes bytes of data a { a data bytes } a = offset DTazeros # of 0 bytes a DTsymsize same as DTazeros, but the type of the symbol gives the size DTcommon # of 0 bytes (in a common block) a DTxoff offset from symbol w a w = symbol number (pointer for CPP) a = offset DTcoff offset into code segment
