struct Target;

static uint alignsize(Type type);

Return memory alignment size of type.

static uint fieldalign(Type type);

Return field alignment size of type.

static uint critsecsize();

Return size of OS critical section.

NOTE: can't use the sizeof() calls directly since cross compiling is supported and would end up using the host sizes rather than the target sizes.

static Type va_listType();

Returns a Type for the va_list type of the target.

NOTE: For Posix/x86_64 this returns the type which will really be used for passing an argument of type va_list.

static int isVectorTypeSupported(int sz, Type type);

Checks whether the target supports a vector type with total size sz (in bytes) and element type type.

Returns:

0 if the type is supported, or else: 1 if vector types are not supported on the target at all, 2 if the element type isn't, or 3 if the given size isn't.

static bool isVectorOpSupported(Type type, TOK op, Type t2 = null);

Checks whether the target supports operation op for vectors of type type. For binary ops t2 is the type of the 2nd operand.

Returns:

true if the operation is supported or type is not a vector

static Expression paintAsType(Expression e, Type type);

Encode the given expression, which is assumed to be an rvalue literal as another type for use in CTFE. This corresponds roughly to the idiom *(Type *)&e.

static void loadModule(Module m);

For the given module, perform any post parsing analysis. Certain compiler backends (ie: GDC) have special placeholder modules whose source are empty, but code gets injected immediately after loading.

static void prefixName(OutBuffer* buf, LINK linkage);

For the given symbol written to the OutBuffer, apply any target-specific prefixes based on the given linkage.

static const(char)* cppTypeMangle(Type t);

For a vendor-specific type, return a string containing the C++ mangling. In all other cases, return null.

static LINK systemLinkage();

Return the default system linkage for the target.
