"""This script takes the file produced by DMD's test mode and checks its
|
|
correctness.
|
|
|
|
It produces the following output files: $TMP/test-{fixed,filtered,diff}.dmd.
|
|
|
|
It runs the appropriate fix* script to get nice stack traces. It also
|
|
filters out platform-specific details from the test output file.
|
|
|
|
Note: you must run this from the same directory that you invoked DMD's test
|
|
mode, otherwise the fix* script will not work properly, because some of the
|
|
paths in the test output are relative.
