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 Note: We split -mabi= into -mabi=lp64d/f/s, the new options not support by upstream binutils yet, this GCC port requires the following patch applied to binutils to build. https://github.com/loongson/binutils-gdb/commit/aacb0bf860f02aa5a7dcb76dd0e392bf871c7586 (will be submitted to upstream after gcc side comfirmed) changelog: v1 -> v2 1. Split patch set. 2. Change some code style. 3. Add -mabi=lp64d/f/s options. 4. Change GLIBC_DYNAMIC_LINKER_LP64 name. v2 -> v3 1. Change some code style. 2. Bug fix. We will donate LoongArch machine to Cfarm for testing. *** BLURB HERE *** chenglulu (12): LoongArch Port: gcc build LoongArch Port: Regenerate gcc/configure.
