SLP fails to recognize valid address expression during SWPointer creation for memory operands with 32 bit jvm, this prevents gathering adjacent memory operations.
Debug trace with -XX:+TraceSuperWord -XX:+TraceNewVectors -XX:CompileCommand=VectorizeDebug,,3 shows following errors .
SWPointer::memory_alignment: SWPointer p invalid, return bottom_align
SWPointer::memory_alignment: SWPointer p invalid, return bottom_align
SWPointer::memory_alignment: SWPointer p invalid, return bottom_align
SWPointer::memory_alignment: SWPointer p invalid, return bottom_align
SWPointer::memory_alignment: SWPointer p invalid, return bottom_align
Problem also exist in JDK17 LTS. As an interim solution to prevent this showing up as a GHA test failure, we can enable the test only for x86_64 and aarch64 targets. Difference in address expression b/w X86 32 and 64 bit jvm will be root caused in follow issue JDK-8303885.
