This PR is in reference to porting LLDB on AIX. Link to discussions on llvm discourse and github: 1. https://discourse.llvm.org/t/port-lldb-to-ibm-aix/80640 2. https://github.com/llvm/llvm-project/issues/101657 The complete changes for porting are present in this draft PR: https://github.com/llvm/llvm-project/pull/102601 **Description:** Adding ParseSymtab logic after creating sections. It is able to handle both 32 and 64 bit symbols, without the need to add template logic. This is an incremental PR on top of my previous couple of XCOFF support commits.
