   1 # Simple-V Spike emulator
   2
   3 example dev script (riscvdev.sh):
   4
   5     export RISCV="$HOME/src/riscv"
   6     export PATH="$PATH:$RISCV/bin"
   7
   8 Needs riscv-tools, first
   9
  10 * git clone https://github.com/riscv/riscv-tools
  11
  12 once compiled check out sv versions of spike and tests:
  13
  14 * git clone https://git.libre-riscv.org/git/riscv-isa-sim.git
  15 * cd risc-v-isa-sim
  16 * git checkout -b sv
  17 * cd ..
  18 * git clone https://git.libre-riscv.org/git/riscv-tests.git
  19 * cd riscv-tests
  20 * git checkout -b sv
  21
  22 make install needed on the simulator for the tests to pick it up
  23
  24 To run the sv unit tests (requires $RISCV to be set correctly i think, or
  25 at least riscv32/64-unknown-elf-gcc to be in the path)
  26
  27 * $ cd riscv-tests
  28 * $ cd isa
  29 * $ make
  30 * $ make run
  31
  32 To override the fact that spike loads libspike\_main.so and other dynamic
  33 libraries from /usr/local/lib (or other location in the path):
  34
  35     $ export LD_LIBRARY_PATH=`pwd`
  36     $ ./spike pk ./a.out
