6.32.6 M32R/D Variable Attributes

One attribute is currently defined for the M32R/D.

model (model-name)

Use this attribute on the M32R/D to set the addressability of an object. The identifier model-name is one of small, medium, or large, representing each of the code models.

Small model objects live in the lower 16MB of memory (so that their addresses can be loaded with the ld24 instruction).

Medium and large model objects may live anywhere in the 32-bit address space (the compiler generates seth/add3 instructions to load their addresses).
