`dmd.target.Target/target` - multiple declarations

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.

Methods

Name	Description
`_init`	Initialize the Target
`alignsize`	Requested target memory alignment size of the given type.
`critsecsize`	Size of the target OS critical section.
`deinitialize`	Deinitializes the global state of the compiler.
`fieldalign`	Requested target field alignment size of the given type.
`getTargetInfo`	Get targetInfo by key
`isReturnOnStack`	Determine return style of function - whether in registers or through a hidden pointer to the caller's stack.
`isVectorOpSupported`	Checks whether the target supports the given operation for vectors.
