Hi Kiman,

Please find out attached files. It looks like the base-7.0.2.2 caused the same result.
- Base-3.16.2 perl epicsCalcTest.t result.
- Base-7.0.2.2 compile result
- Base-7.0.2.2 perl epicsCalcTest.t result.
Thanks. I think you would probably be fine using either Base version. The test failures you're seeing involve some unusual combinations of mostly bit-wise operators in the CALC _expression_ evaluation engine. The rest of the tests imply the IOC code should run
normally, except for some kinds of expressions in CALC records.

For reference, here are just the failing tests from Kiman's epicsCalcTest runs, both 3.16.2 and 7.0.2.2 gave him the same results. For once this might not be a simple _expression_ optimizer issue since the "expected" results look to be correct — they get generated
by compiling the _expression_ as C++ code, while the actual result comes from executing the byte-code shown below the values.
Anybody got any ideas, or access to an ARM aarch64 box?
