 My clang is canadian compiled from Linux. Its default target is x86_64-windows-gnu. Set it to x86_64-windows-msvc to ensure every clang works. My Canadian clang compiler is here. https://github.com/trcrsired/windows-hosted-llvm-clang

看样这个功能可以考虑加到fast_io中

https://github.com/cppfastio/fast_io/blob/master/include/fast_io_hosted/platforms/linux/loongarch64.h 还有能帮我看下这个系统调用的实现对么？我是从loongarch克隆的libc查的。传参的寄存器和riscv64一样的

还有类似arm memory tagging extension有考虑扩展一下么？内存标记是目前最有效的保护内存安全问题的解决方案。

1. you do not need to write a custom device for std::string in fast_io. Just use ibuffer_view https://github.com/cppfastio/fast_io/blob/8ba73cb3d1dfcbed79214e0a11f5d863fc16664f/tests/0002.printscan/scan.cc 2. ```cpp fast_io::to("214124214") ``` is another way to work, except it does...

``` clang++ -o construct_fstream_from_syscall construct_fstream_from_syscall.cc -Ofast -std=c++2b -s -fuse-ld=lld -I../../include -flto=thin --target=loongarch64-linux-gnu --sysroot =$HOME/toolchains/x86_64-w64-mingw32/loongarch64-linux-gnu In file included from construct_fstream_from_syscall.cc:1: In file included from ../../include/fast_io_legacy.h:25: In file included from ../../include/fast_io.h:9: In...

It looks like it is the LLVM's issue. There is nothing i can do about it right now. Probably the situation will get fixed soon.

``` error: unable to create target: 'No available targets are compatible with triple "loongarch64-unknown-linux-gnu"' 1 error generated. ```

can you show me the target of compiler?
