1. Get QEMU-riscv64: pacman -S qemu-arch-extra
2. Compile riscv-gnu-toolchain

   1.  git clone https://github.com/riscv-collab/riscv-gnu-toolchain && cd riscv-gnu-toolchain

   2. Install dependencies:

      sudo pacman -Syyu autoconf automake curl python3 libmpc mpfr gmp gawk base-devel bison flex texinfo gperf libtool patchutils bc zlib expat

   3.  ./configure --prefix=/opt/riscv

   4.  make && make linux

   5. add export PATH="/opt/riscv/bin/:$PATH" to the file .zshrc or .bashrc

To be sure your dev-env is ready try to compile hello_world.c and run it through qemu-riscv64:

riscv64-unknown-elf-gcc -static -Wall --pedantic hello_world.c
qemu-riscv64 a.out

For more details see: https://saveriomiroddi.github.io/Quick-riscv-cross-compilation-and-emulation/

To set an handful of useful aliases run:

source configure_env

Now you can run build filename.s, run exec.out and debug exec.out.
