资 源 简 介
This project aims at porting GCC to support the NEC SX vector CPU (SX6 - SX9). Targets of the project are:
* Document the SX assembler instructions, scalar CPU registers and existing calling conventions by using information from existing and openly available reference guides. This step is a prerequisite for such an open source effort.
* Write Machine description, expander definitions and insn patterns for SX CPU.
* Get GCC to produce assembler code for the SX, focus on scalar instructions.
This project doesn"t aim to produce a competitive vectorizing compiler for the SX, the knowhow for that is far too special and the effort too high. Instead it aims at a compiler producing correct scalar code, as basis for further open-source projects for the SX architecture.
