             Summary: Remove LlvmCodeGen::CastPtrToLlvmPtr
                 Key: IMPALA-10196
                 URL: https://issues.apache.org/jira/browse/IMPALA-10196
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Daniel Becker
            Assignee: Daniel Becker


LlvmCodeGen::CastPtrToLlvmPtr embeds a pointer that points to data in the current process's memory into codegen'd IR code. Our long term goal is to share the codegen'd IR among processes working on the same fragment, which is not possible if the IR contains pointers pointing to data of a specific process. A step in making the IR independent of the process generating it is removing LlvmCodeGen::CastPtrToLlvmPtr.
