The scripts that generate the litmus tests in the "auto" directory of the https://github.com/paulmckrcu/litmus archive place the "Result:" tag into a single-line ocaml comment, which judgelitmus.sh currently does not recognize. This commit therefore makes judgelitmus.sh recognize both the multiline comment format that it currently does and the automatically generated single-line format. Signed-off-by: Paul E.

# Given a .litmus test and the corresponding litmus output file, check
|
|
# the .litmus.out file against the "Result:" comment to judge whether the
|
|
# test ran correctly. If the --hw argument is omitted, check against the
|
|
# LKMM output, which is assumed to be in file.litmus.out. If either a
|
|
# "DATARACE" marker in the "Result:" comment or a "Flag data-race" marker
|
|
# in the LKMM output is present, the other must also be as well, at least
|
|
# for litmus tests having a "Result:" comment. In this case, a failure of
|
|
# the Always/Sometimes/Never portion of the "Result:" prediction will be
|
|
# noted, but forgiven.
|
|
#
|
|
# If the --hw argument is provided, this is assumed to be a hardware
|
|
# test, and the output is assumed to be in file.litmus.HW.out, where
|
|
# "HW" is the --hw argument. In addition, non-Sometimes verification
|
|
# results will be noted, but forgiven. Furthermore, if there is no
|
|
# "Result:" comment but there is an LKMM .litmus.out file, the observation
|
|
# in that file will be used to judge the assembly-language verification.
