#!/bin/sh
# Use `./bin/check-compiler-flag FLAG` to check the behaviour of the given compiler flag.
# This is useful if `crystal build` is affected when using `-DFLAG` option.
#
# This script will
# * run the compiler_spec using the flag
# * build the compiler to have the flag available (in case the flag is introduced in this version)
# * run the std_spec and primitives_spec with and without the flag
# * check the compiler_spec built with and without the flag (eg: the specs build with the flag can generate a compiler without the flag)
# * build a 2nd generation of the compiler using the flag
# * repeat the checks for the spec suites with and without the flag
