tools/memory-model: Split runlitmus.sh out of checklitmus.sh This commit prepares for adding --hw capability to github litmus-test scripts by splitting runlitmus.sh (which simply runs the verification) out of checklitmus.sh (which also judges the results).

tools/memory-model: Make runlitmus.sh generate .litmus.out for --hw In the absence of "Result:" comments, the runlitmus.sh script relies on litmus.out files from prior LKMM runs. This can be a bit user-hostile, so this commit makes runlitmus.sh generate any needed .litmus.out files that don't already exist. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

tools/memory-model: Move from .AArch64.litmus.out to .litmus.AArch.out When the github scripts see ".litmus.out", they assume that there must be a corresponding C-language ".litmus" file. Won't they be disappointed when they instead see nothing, or, worse yet, the corresponding assembly-language litmus test? This commit therefore swaps the hardware tag with the "litmus" to avoid this sort of disappointment. This commit also adjusts the .gitignore file so as to avoid adding these new ".out" files to git.

tools/memory-model: Add -v flag to jingle7 runs Adding the -v flag to jingle7 invocations gives much useful information on why jingle7 didn't like a given litmus test.

tools/memory-model: Use "-unroll 0" to keep --hw runs finite Litmus tests involving atomic operations produce LL/SC loops on a number of architectures, and unrolling these loops can result in excessive verification times or even stack overflows. This commit therefore uses the "-unroll 0" herd7 argument to avoid unrolling, on the grounds that additional passes through an LL/SC loop should not change the verification. Note however, that certain bugs in the mapping of the LL/SC loop to machine instructions may go undetected. On the other hand, herd7 might not be the best vehicle for finding such bugs in any case. (You do stress-test your architecture-specific code, don't you?) Suggested-by: Luc Maranget <luc.maranget@inria.fr> Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
