Hi, all:
This is the v10 version of LoongArch Port based on d1ca63a1b7d5986913b14567a4950b055a5a3f07.
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.
