1 ============ 2 LKMM SCRIPTS 3 ============ 4 5 6 These scripts are run from the tools/memory-model directory. 7 8 checkalllitmus.sh 9 10 Run all litmus tests in the litmus-tests directory, checking 11 the results against the expected results recorded in the 12 "Result:" comment lines. 13 14 checkghlitmus.sh 15 16 Run all litmus tests in the https://github.com/paulmckrcu/litmus 17 archive that are C-language and that have "Result:" comment lines 18 documenting expected results, comparing the actual results to 19 those expected. 20 21 checklitmushist.sh 22 23 Run all litmus tests having .litmus.out files from previous 24 initlitmushist.sh or newlitmushist.sh runs, comparing the 25 herd7 output to that of the original runs. 26 27 checklitmus.sh 28 29 Check a single litmus test against its "Result:" expected result. 30 Not intended to for manual use. 31 32 checktheselitmus.sh 33 34 Check the specified list of litmus tests against their "Result:" 35 expected results. This takes optional parseargs.sh arguments, 36 followed by "--" followed by pathnames starting from the current 37 directory. 38 39 cmplitmushist.sh 40 41 Compare output from two different runs of the same litmus tests, 42 with the absolute pathnames of the tests to run provided one 43 name per line on standard input. Not normally run manually, 44 provided instead for use by other scripts. 45 46 initlitmushist.sh 47 48 Run all litmus tests having no more than the specified number 49 of processes given a specified timeout, recording the results 50 in .litmus.out files. 51 52 judgelitmus.sh 53 54 Given a .litmus file and its herd7 output, check the output file 55 against the .litmus file's "Result:" comment to judge whether 56 the test ran correctly. Not normally run manually, provided 57 instead for use by other scripts. 58 59 newlitmushist.sh 60 61 For all new or updated litmus tests having no more than the 62 specified number of processes given a specified timeout, run 63 and record the results in .litmus.out files. 64 65 parseargs.sh 66 67 Parse command-line arguments. Not normally run manually, 68 provided instead for use by other scripts. 69 70 runlitmushist.sh 71 72 Run the litmus tests whose absolute pathnames are provided one 73 name per line on standard input. Not normally run manually, 74 provided instead for use by other scripts. 75 76 README 77 78 This file 79 80 Testing a change to LKMM might go as follows: 81 82 # Populate expected results without that change, and 83 # runs for about an hour on an 8-CPU x86 system: 84 scripts/initlitmushist.sh --timeout 10m --procs 10 85 # Incorporate the change: 86 git am -s -3 /path/to/patch # Or whatever it takes. 87 88 # Test the new version of LKMM as follows... 89 90 # Runs in seconds, good smoke test: 91 scripts/checkalllitmus.sh 92 93 # Compares results to those produced by initlitmushist.sh, 94 # and runs for about an hour on an 8-CPU x86 system: 95 scripts/checklitmushist.sh --timeout 10m --procs 10 96 97 # Checks results against Result tags, runs in minutes: 98 scripts/checkghlitmus.sh --timeout 10m --procs 10 99 100 The checkghlitmus.sh should not report errors in cases where the 101 checklitmushist.sh script did not also report a change. However, 102 this check is nevertheless valuable because it can find errors in the 103 original version of LKMM. Note however, that given the above procedure, 104 an error in the original LKMM version that is fixed by the patch will 105 be reported both as a mismatch by checklitmushist.sh and as an error 106 by checkghlitmus.sh. One exception to this rule of thumb is when the 107 test fails completely on the original version of LKMM and passes on the 108 new version. In this case, checklitmushist.sh will report a mismatch 109 and checkghlitmus.sh will report success. This happens when the change 110 to LKMM introduces a new primitive for which litmus tests already existed.
