-Subject: [PATCH] Adding volatile modifier to tmp variable in memory test
-
-Issue explanation:
-
-./sysbench/sysbench --test=memory --num-threads=16 \
- --memory-block-size=268435456 \
- --memory-total-size=137438953472 \
- --memory-oper=read \
- --memory-access-mode=seq \
- --memory-scope=local run
-
-Without this commit the time to run the above command is 0.0004 seconds.
-With this commit the time is greater than 3 seconds. Essentially,
-without the volatile modifier, the compiler optimizes read access so
-that no real access happens.
-
-Upstream-Status: Backport [part of v1.0.0 https://github.com/akopytov/sysbench/commit/8753cb93be4c0b81a20b704ced91e7a422da52b1]
