# This is a toolchain file designed to allow *developers*
# to locally run the RISC-V Vector extensions correctness tests.
#
# We assume the developer machine has two auxiliary programs:
# 1. Spike --- ISA-level simulator
# 2. Proxy kernel --- thin layer that allows to run simple
# C programs on top of Spike.
#
# Usage:
# $ cmake -DCMAKE_TOOLCHAIN_FILE=toolchain-rvv-spike.cmake
