The https://github.com/paulmckrcu/litmus repository contains a large number of C-language litmus tests that include "Result:" comments predicting the verification result. This commit adds a number of scripts that run tests on these litmus tests: checkghlitmus.sh: Runs all litmus tests in the https://github.com/paulmckrcu/litmus archive that are C-language and that have "Result:" comment lines documenting expected results, comparing the actual results to those expected. Clones the repository if it has not already been cloned into the "tools/memory-model/litmus" directory. initlitmushist.sh Run all litmus tests having no more than the specified number of processes given a specified timeout, recording the results in .litmus.out files. Clones the repository if it has not already been cloned into the "tools/memory-model/litmus" directory. newlitmushist.sh For all new or updated litmus tests having no more than the specified number of processes given a specified timeout, run and record the results in .litmus.out files. checklitmushist.sh Run all litmus tests having .litmus.out files from previous initlitmushist.sh or newlitmushist.sh runs, comparing the herd output to that of the original runs. The above scripts will run litmus tests concurrently, by default with one job per available CPU. Giving any of these scripts the --help argument will cause them to print usage information. This commit also adds a number of helper scripts that are not intended to be invoked from the command line: cmplitmushist.sh: Compare the output of two different runs of the same litmus test. judgelitmus.sh: Compare the output of a litmus test to its "Result:" comment line. parseargs.sh: Parse command-line arguments. runlitmushist.sh: Run the litmus tests whose pathnames are provided one per line on standard input. While in the area, this commit also makes the existing checklitmus.sh and checkalllitmus.sh scripts use parseargs.sh in order to provide a bit of uniformity. In addition, per-litmus-test status output is directed to stdout, while end-of-test summary information is directed to stderr. Finally, the error flag standardizes on "!!!" to assist those familiar with rcutorture output. The defaults for the parseargs.sh arguments may be overridden by using environment variables: LKMM_DESTDIR for --destdir, LKMM_HERD_OPTIONS for --herdoptions, LKMM_JOBS for --jobs, LKMM_PROCS for --procs, and LKMM_TIMEOUT for --timeout.

LKMM SCRIPTS
|
|
============
|
|
|
|
|
|
These scripts are run from the tools/memory-model directory.
|
|
|
|
checkalllitmus.sh
|
|
|
|
Run all litmus tests in the litmus-tests directory, checking
|
|
the results against the expected results recorded in the
|
|
"Result:" comment lines.
|
|
|
|
checkghlitmus.sh
|
|
|
|
Run all litmus tests in the https://github.com/paulmckrcu/litmus
|
|
archive that are C-language and that have "Result:" comment lines
|
|
documenting expected results, comparing the actual results to
|
|
those expected.
|
|
|
|
checklitmushist.sh
|
|
|
|
Run all litmus tests having .litmus.out files from previous
|
|
initlitmushist.sh or newlitmushist.sh runs, comparing the
|
|
herd output to that of the original runs.
|
|
|
|
checklitmus.sh
|
|
|
|
Check a single litmus test against its "Result:" expected result.
|
|
|
|
cmplitmushist.sh
|
|
|
|
Compare output from two different runs of the same litmus tests,
|
|
with the absolute pathnames of the tests to run provided one
|
|
name per line on standard input. Not normally run manually,
|
|
provided instead for use by other scripts.
|
|
|
|
initlitmushist.sh
|
|
|
|
Run all litmus tests having no more than the specified number
|
|
of processes given a specified timeout, recording the results
|
|
in .litmus.out files.
|
|
|
|
judgelitmus.sh
|
|
|
|
Given a .litmus file and its .litmus.out herd output, check the
|
|
.litmus.out file against the .litmus file's "Result:" comment to
|
|
judge whether the test ran correctly. Not normally run manually,
|
|
provided instead for use by other scripts.
|
|
|
|
newlitmushist.sh
|
|
|
|
For all new or updated litmus tests having no more than the
|
|
specified number of processes given a specified timeout, run
|
|
and record the results in .litmus.out files.
|
|
|
|
parseargs.sh
|
|
|
|
Parse command-line arguments. Not normally run manually,
|
|
provided instead for use by other scripts.
|
|
|
|
runlitmushist.sh
|
|
|
|
Run the litmus tests whose absolute pathnames are provided one
|
|
name per line on standard input. Not normally run manually,
|
|
provided instead for use by other scripts.
