Target

Describes a back-end target. At present it is incomplete, but in the future it should grow to contain most or all target machine and target O/S specific information.

In many cases, calls to sizeof() can't be used directly for getting data type sizes since cross compiling is supported and would end up using the host sizes rather than the target sizes.

Members

Functions

_init void _init(Param params): Initialize the Target
alignsize uint alignsize(Type type): Requested target memory alignment size of the given type.
critsecsize uint critsecsize(): Size of the target OS critical section.
deinitialize void deinitialize(): Deinitializes the global state of the compiler.
fieldalign uint fieldalign(Type type): Requested target field alignment size of the given type.
getTargetInfo Expression getTargetInfo(const(char)* name, Loc loc): Get targetInfo by key
isReturnOnStack bool isReturnOnStack(TypeFunction tf, bool needsThis): Determine return style of function - whether in registers or through a hidden pointer to the caller's stack.
isVectorOpSupported bool isVectorOpSupported(Type type, ubyte op, Type t2): Checks whether the target supports the given operation for vectors.
isVectorTypeSupported int isVectorTypeSupported(int sz, Type type): Checks whether the target supports a vector type.
isXmmSupported bool isXmmSupported()
parameterSize ulong parameterSize(Loc loc, Type t): Determine the size a value of type t will be when it is passed on the function parameter stack.
systemLinkage LINK systemLinkage(): Default system linkage for the target.
toArgTypes TypeTuple toArgTypes(Type t): Describes how an argument type is passed to a function on target.
va_listType Type va_listType(): Type for the va_list type for the target. NOTE: For Posix/x86_64 this returns the type which will really be used for passing an argument of type va_list.
