[drlvm][jitrino][opt] cafl should be reworked.

                 Key: HARMONY-5028
                 URL: https://issues.apache.org/jira/browse/HARMONY-5028
             Project: Harmony
          Issue Type: Improvement
          Components: DRLVM
         Environment: win/lin-ia32
            Reporter: Dmitry B. Yershov
            Priority: Minor
         Attachments: cafl.zip

    Current implementation of optimization "cafl" is rather limited. For example, it doesn't
analyze memory operands which doesn't have "base" sub operand or which has "index" sub operand.
I've implemented new version of "cafl". It tries to analyze each sub operand of memory operand.
You can find diff with implemented feature in attachment.

This feature was tested on the following configurations:
    Windows_ia32_msvc_debug - build test, EHWA eclipse3.2
    Windows_ia32_msvc_release - build test, EHWA eclipse3.2
    Linux_a32_gcc_debug - build test
    Linux_a32_gcc_release - build test
    win_em64t_msvc_debug - build test

By the way, I've run "Hello World" application and counted changed memory operands:
Current "cafl" - 3744 changed memory operands
New "cafl" - 5174 changed memory operands
