With the initial support added, clang can compile simple .c
to executable file for loongarch64. For example:
$ cat main.c
int main() {
return 0;
}
$ clang --target=loongarch64-linux-gnu --gcc-toolchain=xxx --sysroot=xxx main.c
Currently gcc toolchain and sysroot can be found here:
https://github.com/loongson/build-tools/releases/download/2022.05.29/loongarch64-clfs-5.0-cross-tools-gcc-glibc.tar.xz
Reference: https://github.com/loongson/LoongArch-Documentation
The last commit hash (main branch) is:
99016636af64d02dee05e39974d4c1e55875c45b
Note loongarch32 is not fully tested because there is no reference
gcc toolchain yet.
