The LoongArch architecture (LoongArch) is an Instruction Set Architecture (ISA) that has a Reduced Instruction Set Computer (RISC) style. The documents are on https://loongson.github.io/LoongArch-Documentation/README-EN.html The ELF ABI Documents are on: https://loongson.github.io/LoongArch-Documentation/LoongArch-ELF-ABI-EN.html The binutils has been merged into trunk: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=560b3fe208255ae909b4b1c88ba9c28b09043307 The ABI -mabi=name is still under discussion and may change in the next version, the rest can be reviewed. chenglulu (7): LoongArch Port: gcc LoongArch Port: Regenerate gcc/configure.
