The Green Hills Optimizing Compilers for 680x0/683xx/CPU32 all utilize a common code generator with architecture-specific optimizations. Each supported processor model has its own particular pipeline and instruction set characteristics. These are accommodated in the code generator to produce code best suited for the target processor. The following 680x0/683xx/CPU32-specific features are supported:

• Processor - One option for each supported 680x0/683xx/CPU32 model. This setting determines the instructions permitted, as well as the pipeline optimization strategy used.
• Use built-in fp functions- Uses built-in floating point instructions rather than calling transcendental library functions.
• Insert extra Fpnops - Appends one FPNOP instruction after every 68881 instruction, ensuring that interrupts are taken at the correct position.
• Return fp in d0/d1 - Returns floating point numbers from functions in the registers d0 and d1 instead of fp0.
• Pop stack args often - Forces an adjustment of the stack when 50 bytes have accumulated.
• Portable assembly code - For assembly output, use constant directives rather than actual 68K instructions.
• Large switch statements - Allows large switch statements by forcing the compiler to use a 32-bit offset.
• Position Independent Code (PIC) and Data (PID) - Allows executable files and data to be placed anywhere in memory and still run correctly.
