platform_test

#! /bin/sh

# This script determines which platforms that this Valgrind installation
# supports.
# We return:
# - 0 if the machine matches the asked-for platform
# - 1 if it didn't match, but did match the name of another platform
# - 2 otherwise

# Nb: When updating this file for a new platform, add the name to
# 'all_platforms'.
