From 4d243ec7fd6f07cd16982bc31bb7ef9d4253b8a9 Mon Sep 17 00:00:00 2001
From: Sakura286 <[email protected]>
Date: Tue, 26 Jul 2022 02:18:23 +0000
Subject: [PATCH] Add riscv64 support
1. Configure gbuild to compile on riscv64
2. Add UNO Bridge for riscv64
Now the welcome page could be established and files could be saved
with Writer on riscv64. Test on Debian sid.
Credits:
- Heiher <[email protected]> and Stephan Bergmann <[email protected]>
contributes the code of UNO bridge for MIPS64 and AArch64,
which I refer to.
- Bo Yu <[email protected]> configures gbuild for riscv64.
- Xuerui Wang <[email protected]> gives lots of guiding tips.
- wjh-la <[email protected]> contributes the code of UNO-
bridge for Loongarch64, which inspired me.
