Variable target

Target target ;

Struct 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.

struct Target ;

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.

isPOSIX[get] bool


_init (params) Initialize the Target
alignsize (type) Requested target memory alignment size of the given type.
deinitialize () Deinitializes the global state of the compiler.
fieldalign (type) Requested target field alignment size of the given type.
getTargetInfo (name, loc) Get targetInfo by key
isCalleeDestroyingArgs (tf)
isReturnOnStack (tf, needsThis) Determine return style of function - whether in registers or through a hidden pointer to the caller's stack.
isVectorOpSupported (type, op, t2) Checks whether the target supports the given operation for vectors.
isVectorTypeSupported (sz, type) Checks whether the target supports a vector type.
isXmmSupported ()
libraryObjectMonitors (fd, fbody) Returns true if the implementation for object monitors is always defined in the D runtime library (rt/monitor_.d).
objectFormat () Determine the object format to be used
preferPassByRef (t) Decides whether an in parameter of the specified POD type is to be passed by reference or by value. To be used with -preview=in only!
setCPU () Determine the instruction set to be used
stackAlign ()
supportsLinkerDirective () Returns true if the target supports pragma(linkerDirective).
systemLinkage () Default system linkage for the target.
toArgTypes (t) Describes how an argument type is passed to a function on target.
va_listType (loc, sc) Type for the va_list type for the target; e.g., required for _argptr declarations.
