I suggest to leave testUnsafeAccess()
intact and adjust testMatched
/testMismatched
to take into account whether Compiler.isGraalEnabled() == true
or not.
… implementation details
Ok, good suggestion - done. |

The
UnsafeGetStableArrayElement
test fails on GraalVM because it asserts implementation specific behavior of C1 and C2. In particular, it asserts that the JIT will not constant fold an unsafe read of a stable array element if the type of the read does not match the type of the array element. For example:The Graal compiler will constant fold these reads where as C1 and C2 will not.
This PR modifies the test to take into account the JIT being used when deciding what to assert.
