Hello!This patch add support for recognizing LoongArch as a valid cpu in config.sub and config.guess.
I added test cases, and they all passed. $ make check cd testsuite && bash config-guess.sh && rm uname cd testsuite && bash config-sub.sh PASS: config.sub checks (821 tests) PASS: config.sub idempotency checks (764 tests) PASS: config.sub canonicalise each config.guess testcase (129 tests) PASS: config.guess checks (129 tests)We're porting downstream software, but almost every software needs to be modified, so hopefully this patch will be accepted here so that future automake versions can be used directly.
If I need to change / add anything, please let me know, thank you. --- From 3366787d4995a9ba288372ffb211782fb20ee37c Mon Sep 17 00:00:00 2001 From: Xiaotian Wu <wuxiaot...@loongson.cn> Date: Thu, 3 Dec 2020 14:18:08 +0800 Subject: [PATCH] Recgnize loongarch32, loongarch64 and loongarchx32* config.guess (loongarch32:Linux:*:*, loongarch64:Linux:*:*, loongarchx32:Linux:*:*): New.
