Bibo Mao f83434f3dc target/loongarch: Add loongarch vector property unconditionally Currently LSX/LASX vector property is decided by the default value. Instead vector property should be added unconditionally, and it is irrelative with its default value. If vector is disabled by default, vector also can be enabled from command line.

README

- Introduction

LoongArch is the general processor architecture of Loongson.

The following versions of the LoongArch core are supported
core: 3A5000
https://github.com/loongson/LoongArch-Documentation/releases/download/2021.08.17/LoongArch-Vol1-v1.00-EN.pdf

We can get the latest loongarch documents at https://github.com/loongson/LoongArch-Documentation/tags.

- System emulation

You can reference docs/system/loongarch/loongson3.rst to get the information about system emulation of LoongArch.

- Linux-user emulation

We already support Linux user emulation. We can use LoongArch cross-tools to build LoongArch executables on X86 machines,
and We can also use qemu-loongarch64 to run LoongArch executables.

1. Config cross-tools env.

see System emulation.

2. Test tests/tcg/multiarch.

./configure --static --prefix=/usr --disable-werror --target-list="loongarch64-linux-user" --enable-debug

cd build

make && make check-tcg

3. Run LoongArch system basic command with loongarch-clfs-system.

- Config clfs env.

wget https://github.com/loongson/build-tools/releases/download/2022.05.29/loongarch64-clfs-system-5.0.tar.bz2

tar -vxf loongarch64-clfs-system-5.0.tar.bz2 -C /opt/clfs

cp /opt/clfs/lib64/ld-linux-loongarch-lp64d.so.1 /lib64

export LD_LIBRARY_PATH="/opt/clfs/lib64"

- Run LoongArch system basic command.

./qemu-loongarch64 /opt/clfs/usr/bin/bash
./qemu-loongarch64 /opt/clfs/usr/bin/ls
./qemu-loongarch64 /opt/clfs/usr/bin/pwd

- Note.
