Please review. We know it is stage4, I think it is ok for a new prot. The kernel side upstream waiting for a approval by gcc side, if it is blocked by stage4, a approval for GCC13 will be appreciation. 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) We have compiled more than 300 CLFS packages with this compiler. The CLFS are currently used on Cfarm machines gcc400 and gcc401. 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. v3 -> v4 1. Change some code style. 2. Bug fix. 3. Delete some builtin macros. v4 -> v5 1. delete wrong insn zero_extendsidi2_internal. 2. Adjust some build options. 3. Change some .c files to .cc. v5 -> v6 1. Fix compilation issues. The generated files *.opt and *.h are generated to $(objdir). v6 -> v7 1. Bug fix. 2. Change some code style. v7 -> v8 1. Add new addressing type ADDRESS_REG_REG support. 2. Modify documentation. 3. Eliminate compile-time warnings. v8 -> v9 1. Undefine the hook TARGET_TRULY_NOOP_TRUNCATION under the architecture. 2. Delete some unsed hooks. 3. Change some code style. 4. Modify documentation. v9 -> v10 1. Modify code style. *** BLURB HERE *** chenglulu (12): LoongArch Port: Regenerate configure LoongArch Port: gcc build LoongArch Port: Regenerate gcc/configure.
