Add these scripts, which can be used to check whether the output
of a new compiler in Java and C# grades is bit-identical to the output
of a known-good old compiler. This is particularly useful on machines
that can't check the correctness of the output in these grades
because they don't have Java or C# compilers installed.

# This script is intended to be used to check whether a new version
|
|
# of the Mercury compiler generates bit-identical output to an old version
|
|
# when generating Java and C# code. We need this ability to avoid introducing
|
|
# regressions on machines that don't have Java and/or C# compilers installed,
|
|
# but it can be useful even on machines that do have them installed.
|
|
#
|
|
# The job of this script is to set up the basis for comparison using
|
|
# the output from an old, known good compiler; the companion script
|
|
# make_java_csharp_diff will then compare this to the output of the new,
|
|
# compiler being tested. The two scripts are separate because during
|
|
# a typical development effort, the second part typically needs to be done
|
|
# significantly more times than the first :-(
|
|
#
|
|
# The user should set the environment variable named BASE_MMC to contain
|
|
# the invocation of the known-good compiler (typically either "mmc" or
|
|
# an instance of tools/lmc) and the environment variable named TEST_MMC
|
|
# to contain the invocation of the compiler under test (typically
|
|
# an instance of tools/lmc). The latter is used by make_java_csharp_diff.
|
|
#
|
|
# This script creates a directory named arena.base that contains
|
|
# all the Mercury source files and interface files from all of the
|
|
# Mercury modules in main Mercury directories of the workspace,
|
|
# and then it puts the known good outputs for the Java and C# grades
|
|
# in arena.base.java and arena.base.csharp respectively.
|
|
# The companion script make_java_csharp_diff then puts the output
|
|
# of the compiler under test in those grades in arena.java and arena.csharp
|
|
# respectively, and compares them to their respective bases.
