From 3eff92b5c9c66570ffc5ce4b0337ca902ec595c9 Mon Sep 17 00:00:00 2001 From: Sakura286 Date: Tue, 26 Jul 2022 02:18:23 +0000 Subject: [PATCH] Add riscv64 support 1. Configure gbuild 2. Add UNO Bridge for riscv64 Till now base function works well on riscv64. Test on Debian, Gentoo and openEuler. Credits: - Heiher and Stephan Bergmann The riscv64 bridge implementation refers to mips64 and AArch64 bridges. - Bo Yu configures gbuild for riscv64. - WANG Xuerui provides lots of guiding tips.
