Lexra Optimizing Compilers

The Green Hills™ Optimizing Compilers for Lexra all utilize a common code generator with architecture-specific optimizations. Each supported Lexra model has its own particular pipeline and instruction set characteristics. Lexra-specific supported features include:

Processor - One option for each supported Lexra model. This setting determines the instructions permitted, as well as the pipeline optimization strategy used.

Position Independent Code (PIC) and Data (PID)- Allows code and data to be created which can be placed anywhere in memory and still run correctly.

PIC Compatible Code - Generate code in a mode such that it can be linked compatibly with PIC and PIC modules and libraries.

64-bit Integers - Supports 64-bit data types, constants, and expressions for Lexra processors that have 64-bit registers.

Far Function Calls - Handles code that exceeds the limits of the Lexra call instruction.

Inline Prologue - Generate inlined code or call a routine when saving and restoring registers.

Small Data Area - Like most RISC processors, Lexra requires two 32-bit instructions to access data stored at an arbitrary 32-bit address. The Green Hills compilers collect frequently accessed variables into a block of up to 64K of memory. This enables single instruction access to data within this block, saving code size and improving performance.
