McKenney <paulmck@xxxxxxxxxx> CommitterDate: Mon, 04 Jan 2021 14:40:49 -08:00 tools/memory-model: Remove redundant initialization in litmus tests This is a revert of commit 1947bfcf81a9 ("tools/memory-model: Add types to litmus tests") with conflict resolutions. klitmus7 [1] is aware of default types of "int" and "int*". It accepts litmus tests for herd7 without extra type info unless non-"int" variables are referenced by an "exists", "locations", or "filter" directive. [1]: Tested with klitmus7 versions 7.49 or later. Suggested-by: Paul E. McKenney <paulmck@xxxxxxxxxx> Signed-off-by: Akira Yokosawa <akiyks@xxxxxxxxx> Signed-off-by: Paul E.
