The Green Hills Optimizing Compilers for i960 all utilize a common code generator with architecture-specific optimizations. Each supported i960 model has its own particular optimization and instruction set characteristics. These are accommodated in the code generator to produce code best suited for the target processor. The following i960-specific features are supported:
 

 

	Processor - One option for each supported i960 model. This set-ting determines the code generation strategy, as well as the pipeline optimization techniques used.
	Big Endian- Generates code with Big-Endian byte order. The most significant byte or an integer appears at the lowest address (the default is little endian).
	Position Independent Code (PIC) and Data (PID) - Allows executable code and data to be placed anywhere in memory and still run correctly.
	Far Function Calls - Loads address of a function into the link register and branches through it. This handles code that exceeds the limits of the i960 call instruction.
	Small Data Area - Allocates a small area of memory to hold data objects and reference objects in that area using a base pointer register. This improves program size and speed because addressing an object via the small data area base register uses smaller instructions and simpler addressing modes.
	Small Data Area Threshold - Specifies a size in bytes to determine which data objects appear in the Small Data Area.
