IA-64 Variable Attributes (Using the GNU Compiler Collection (GCC)) (original) (raw)

6.4.2.6 IA-64 Variable Attributes ¶

The IA-64 back end supports the following variable attribute:

model (model-name) ¶

On IA-64, use this attribute to set the addressability of an object. At present, the only supported identifier for model-name issmall, indicating addressability via “small” (22-bit) addresses (so that their addresses can be loaded with the addlinstruction). Caveat: such addressing is by definition not position independent and hence this attribute must not be used for objects defined by shared libraries.
